Mitsubishi

Technically this is not Uni but it is Mitsubishi. Does anyone know the model/era of this one? It is not a vintage pentel but it has a classic look to it and is a double-knock.

*Thread Reply:* I asked around a bit and it appears that it is a M5-53

That one I don’t know. We need Ray in here.

This is true. I'll invite him again. I figured that @2nd_astronaut might also be someone who would have a clue on this one.

*Thread Reply:* I think I have the model, but I have no clue about number or so. Even worse, I don't know the relation Uni <-> Mitsubishi (thought Uni was a tradename of certain Mitsubishi stationary) ...

*Thread Reply:* Pretty sure this piece is from the pre-Uni era

*Thread Reply:* Mitsubishi → Uni ↓ BOXY

*Thread Reply:* Also Brain and Exceed!

*Thread Reply:* Good points! I think the Exceed lineup was basically a price grab; they used a lot of open source parts (like Schmidt mechanisms) and kind of lost some of their Mitsubishi flair

*Thread Reply:* Pilot did a little bit of this with their Elite lineup

I spoke with Ray yesterday. He’ll be joining.

One of the best pencils in this package is a Mitsubishi. It is hard to tell from the picture but the printing is metallic blue and shifts in the light. I don't have any clue about the model number.

That's gorgeous.

I have a few Mitsubishis. My favorite is the Pecker.

*Thread Reply:* I'm not going to talk about that. There is nothing safe to say in response.

You can't have a side knock collection without a Pecker

There are more Mitsubishis coming. Some of the best ones have a real mid-century vibe.

I like the Boxys. I have some somewhere.

The Boxys are nice. There are some interesting designs where many things were tried and variations on those things were also tried. It is impressive that there were so many that featured fully or partially metal bodies. The internals: they were okay but lacking the innovation/variation of the bodies.

Here's one of my Boxy pencils. (Yeah I'm breaking the mechanical pencil rule)

*Thread Reply:* This points out something with Mitsubishi/Uni/Boxy: really similar models are branded with each. Brain might be the same but I have not seen as many of those.

Not sure if anyone is interested or not, but there is a nice Mitsubishi Pecker on Mercari, https://jp.mercari.com/item/m87046355778

yea at least one Pecker is a requirement for a Quicker Clicker collection. I don't plan on purchasing anymore.....until I find a yellow one 🙂

These Mitsubishi Yoko2’s are in my next shipment

image.png

nice. Where did you find them?

Mercari

killer

Supposedly unused

$8 before Buyee taxes

yeah. they are usually super cheap. Not a typical collector's item. Except for that weird side knock dude in Austin

I figured for that price, couldn’t hurt and I do like other examples of the side knock

It pains me to call this sub-forum Uni instead of Mitsubishi

*Thread Reply:* Cuz we named our Constantinople channel Istanbul

*Thread Reply:* lol

since Mitsubishi came first

hmm, seems you have a point

It's really interesting to look at Mitsubishi/Uni offerings to see which pieces were used during which time frames

and with which branding

Lots of crossover between Uni and BOXY

some similar crossover between Mitsubishi and BOXY (and Mitsubishi and Uni, too, which you would expect)

My drawer is sort of organized along those lines

bottom 3 sets (horizontally oriented) = MX-552, MX-1052 + Automatic Pencil 3 & 5 (which are re-branded Lions), and then double knocks

vertical row 1 (above the horizontal row) = Mitsubishi

vertical row 2 = BOXY

vertical row 3 = Uni

Each row contains some pencils that maybe don't belong there, but I grouped them according to tip style, cap style, clip style, etc

The Uni era is absolutely dominated by a very particular tip style

conical tip, 2-4mm lead sleeve, 2 spiral grooves, 1 deep cut groove to improve grip

And you can see Mitsubishi's evolution into this tip style if you look at vertical row 1 in my pic (https://pearsonified.com/images/pencils/mitsubishi-low.jpg)

Original URL: https://pearsonified.com/images/pencils/mitsubishi-low.jpg

I only have a few Uni’s

Check out the first 20 or so pencils on the left—they have a double graduated conical tip section that would later evolve into the Uni tip

I was surprised to discover the MX-552 and MX-1052 tip styles were pretty significant departures for Mitsubishi

and if I'm not mistaken, the first entry into that style was the Uni mehcanical pencil (3 specimens in vertical row 3, top leftmost corner)

What do you do to keep track of all the details?

They're all in my head right now

I'll have all this on my website and a Google Sheet by the end of the year

holy smokes, check out this beauty: https://ameblo.jp/staedler-rotring/image-11668403458-12738329196.html

color window instead of lead hardness window? 🤯

I was wondering if that was the same pencil!

Here is my Pecker. She's very photogenic.

I don't plan on collecting all of the variations but I will snag a yellow one if I come across one.

Image from iOS

Can't believe you just show your Pecker to a room of strangers

This particular model is GREAT, and I had no idea a yellow one existed

I've only seen red, black, and black + silver

And one of the Pecker models has a metal grip section

I just noticed yours is squarish. Unlike this one: https://jp.mercari.com/item/m87046355778

How long did they make those?

The one you linked is a Pecker Deluxe; I know of at least 3 models: Pecker, Pecker Deluxe, and Pecker GX.

There are probably others, but I can't be sure because I've never seen a Mitsubishi catalog for MPs!

Ah

That's hard to believe

Here are the 3 I know about

It's WILD that so few catalogs are available online. I mean, seriously—you can pick out damn near any industry you like, and you can find catalogs all the way back to antiquity.

But MPs? Nothing.

I purchased the top style recently

It's in this box I'm opening now

Nice

Can confirm the top style Pecker pictured above is fantastic

(that's what she said?)

Someone needs to scoop this up:

Rare one… I actually have the ballpoint and at one time I just thought it was the companion to the M-1052 pencils. And then one day I saw the proper MP with conical tip. Fully expect this to hit 5-6000

I got one for 3500 because the seller used a bad thumbnail image

you couldn't tell what it was unless you clicked through

Considering the high rarity, I was surprised this auction closed at such a low price (especially given recent activity, which has been as high as I've ever seen):

Welp, I knew this double knock came in black + silver and copper + silver (very rare!), but I didn't know it also came in silver + silver!

mitsubishi-double-knock-silver-silver.jpeg

These are some of the very best double knocks ever produced. 10 of the black + silver version were recently sold on YAJ in an expensive lot, but I rarely see the other two.

A copper + silver version came up on YAJ in summer 2021 but was ended abruptly; it later appeared on Mercari but was ended abruptly there, too!

I've never seen the silver + silver version for sale 😳

*Thread Reply:* Never knew the model number but I chose the copper version over the black/silver when bidding on it several years ago…

Uni "Switch" Alpha Gel Kuru Toga Un-Enveloping

*Thread Reply:* Good vid! Seems ‘military green’ has become a popular scheme not just for Pentel Smash, Calme etc.

That green/black KT Switch is the first one of this line that I actually want to own. Well… maybe the yellow/black as well :-)

I worried that this new Kuru Toga Drive means I'm going to have to buy it. Don't really want to, but feel like maybe its a "must have" for any collection.

How does Drive differ from basic, Advance, or Switch?

*Thread Reply:* I've no idea... other than it seems to be the fancy version, the orenznero of kuru toga :)

*Thread Reply:* I think it has an auto advance system as well as lead rotation.... that actually makes me feel less pressured to buy it 🙂

*Thread Reply:* I saw an Instagram post for the Dive today (of course)—echoing @Kiwi-d, it's Kuru Toga + auto advance + lead advance tuning

*Thread Reply:* Who is widely credited with the first auto advance pencil? I'd think it's between Pilot and Staedtler, but I haven't looked into it (as I don't particularly care for automatic mechanisms)

*Thread Reply:* Kuru Toga + auto advance + lead advance tuning

That sounds like an Ohto pencil.

Another solution waiting for an actual problem.

Wondering if the cap will post… and, I do find auto feed models like a vanity project. In extended writing sessions, I find the act of clicking for lead an important part of relaxing my grip and avoiding cramps.

*Thread Reply:* Yes, clicking away is important

Already seeing Kuru Toga DIVE specimens on Mercari 😂

They're selling for over ¥15,000, too!

I will take the 1777 yen version, thank you

*Thread Reply:* The bigger question is what are you doing with a Mitsubishi in your presence?

*Thread Reply:* I have a few Mitsubishis. This one feels like an odd-ball which puts it squarely in the middle of my non-Pentel collecting interests.

The first two posts on this channel are pictures of some of mine.

*Thread Reply:* Yes, that's an M5-55! It was available in black, wine red, and hunter green, and the clips are this bronze-y accent color. Very cool pencils!

*Thread Reply:* This actually brings up another oddity with Mitsubishi model numbers I'll be exploring this year:

Based on the pricing tags on many of my pencils, it LOOKS like Mitsubishi may have simply re-used model numbers over the years.

I had suspected this for a while, but recently, I received a Mitsubishi W-knock with a pricing tag I'd seen before: M5-57.

The problem?

Mitsubishi's executive models from that era came with similar—or sometimes identical—model numbers.

The attached image is of an M5-56, but Mitsubishi released 3 variants of this pencil with different model numbers depending on the joint between grip and barrel:

• Ring joint = MX-55 • No joint = MX-56 • Stepped joint = MX-57 If everything above is true, then my W-knock contains what must be considered a pricing-only sticker—giving no indication of the model—OR a "fake," as someone may have removed the price tag from an actual M5-57 at some point and placed it on the W-knock.

Vintage-nos-Mitsubishi-05mm-m5-50-Mechanical-Pencil.jpg

*Thread Reply:* We do know this:

MX-55

M = sharp, kinda like Pilot's H designation X = lead size (3, 4, 5, 7, 9)

First digit = Price? Or variant? Second digit = Price? Or variant?

*Thread Reply:* If we look at a longer model number like the M4-1052, we gain more insight:

First digit indicates price; second digit indicates something about the variant.

M4-552

M4-1052 = ¥1000 M4-552 = ¥500

In this case, I can only assume the 52 signals a drafting pencil

*Thread Reply:* I suspect the sticker on my W-knock is rogue

*Thread Reply:* Also looks like the M designation is for Mitsubishi; on Uni model numbers, M is replaced by UNI

*Thread Reply:* (Unsure why they wouldn't have simply used a U here instead)

*Thread Reply:* Likewise, BOXY model numbers are prefixed with BX

I'm glad I now have no interest in Kuru Toga Dive. 🙂

I'm going to wait for the hype to die down. There's a specialty stationery store called THINK in Singapore that has brought in plenty of premium lines… S30, Orenznero, Kerry 50th, etc. No doubt KT Dive will be here once production ramps up.

Where is the Dive even being sold right now?

My favorite thing about the Kuru Toga mechanism is turning it off

lololol Dive prices are already down in the ~¥8000 range

Apparently limited to 5,000 pieces worldwide.

I may be a curmudgeon, but I have a LOT more confidence in simple pencils than I do these overwrought, "hi mecha" pieces

*Thread Reply:* Now that is 🔥

Not an MP, but a data point regarding BOXY. The basic BOXY 100 ballpoint came out in 1975…

https://twitter.com/odanii0414/status/835658795917295616?s=21&t=4QMbWlCJg0gmIUD78p2VsQ|https://twitter.com/odanii0414/status/835658795917295616?s=21&t=4QMbWlCJg0gmIUD78p2VsQ

*Thread Reply:* Surprised the BOXY branding goes back that far!

Another BOXY data point from a Tweet: According to the kanji, this model is the BOXY PENCIL M5-100 BX.

So by extension, the 150 yen model with the metal tip and clip would be the M5-150 BX.

*Thread Reply:* @sideKnocks (atxalais), this is a knock pencil 😁

*Thread Reply:* Kelvin, have you noticed that Mitsubishi re-used the same model numbers on different pencils? It's maddening.

*Thread Reply:* Heh heh. Yesssss. Their system of using price point for the part after Mx-… probably ran out of logical space in no time.

*Thread Reply:* So bad. There are a few M5-50s, M5-55s, M5-56s, and M5-57s 😔

Is this a M3-50? I am trying to find the model number.

0422221727~2.jpg

*Thread Reply:* Technically, this was released—at least for a little while—with pricing stickers that said MX-50

*Thread Reply:* But Mitsubishi also produced other pencils with the exact same model number—namely, the M5-50, one of their earliest drafting pencils (there's a Faber-Castell pencil that is identical to this one, but in green)

*Thread Reply:* As far as your pencil is concerned, Mitsubishi also produced the MX-56 (no ring joint between grip and barrel) and the MX-57, which featured a grooved ring joint.

The MX-50 was available in at least 3 axis sizes (short, medium, full); the MX-56 came in short and full (unsure about medium); and the MX-57 came in short and medium (unsure about full).

And then if you really want to get annoyed, you have to endure the fact Mitsubishi produced the M5-55—a hybrid drafting pencil—and gave it a model number that interrupts the natural sequence of its executive lineup.

Curious about the M5-55? See red and green specimens in positions 3 and 4 of the first vertically-oriented row above the horizontal rows:

*Thread Reply:* So moral of the story is this:

I would not go on some hardcore journey trying to find Mitsubishi model numbers. They used the same model numbers over and over again, rendering them completely useless.

For example, they also released a W-knock series with the model number M5-57, which directly conflicts with their ring-jointed executives from above.

*Thread Reply:* So obviously, if you were to attempt to use model numbers to refer to these pencils, you would be introducing serious confusion.

Much better—and CLEARER—to say "W-knock" than something autistically cryptic like "M5-57"

*Thread Reply:* Thanks for the information and advice. There is nothing wrong with being autistic.

Mitsubishi must have had a way to uniquely designate pencils internally. Maybe these did not make it out to the customer level so we may never a have a clean way to assign one designation to a pencil. The quest for model numbers and understanding how they relate to the pencils is part of the hobby for me.

*Thread Reply:* And I'm letting you know that LOTS of collectors share this sentiment. And they have been grossly disappointed with Mitsubishi, which—like I said—did not apply a consistent model numbering scheme. Their numbers literally only refer to lead sizes, intended country of distribution, and price point. If you think through this arrangement, you are absolutely going to run into problems with duplicates

*Thread Reply:* Pentel has always done the best job with model numbers. Pilot is perhaps a DISTANT second, as they used different model numbers within Japan and internationally (and the Japanese model numbers are cryptic beyond belief, to the point of being almost useless)

*Thread Reply:* "OH yeah, that's an HQ-200R-R!" ~ nobody

*Thread Reply:* No, fam—that's a red Pilot Quatro, ¥2000 version

*Thread Reply:* "Oh, I LOVE that HH-100R-B-05!" ~ nobody

*Thread Reply:* No, fam, THAT is an "H-1005" or "Vanishing Point"

*Thread Reply:* It's like anything else. Over time, the simplest reference will always win out.

*Thread Reply:* Stainless steel Boxy with olive green bits.

*Thread Reply:* Another case where your desired distinction will come in some form other than model numbers:

That Uni Flicker is simply the ¥1000 variant with plastic grip section.

Uni also produced an all-aluminum ¥700 variant (no plastic grip) that has much more understated styling.

*Thread Reply:* The same goes for your BOXY—that's a rare steel hybrid with color accent. It was also available with orange and black accents; unsure if any other colors were offered

*Thread Reply:* When BOXY model numbers are mentioned in catalogs, they almost always take the form:

[known model number] + BX

So something like:

M5-1010BX

*Thread Reply:* Even this is not consistent. On the boxed set I posted about earlier the model number is shown as M5-100BOXY. For my purposes a model number is okay even if it is not completely unique. Color and other features can be used to distinguish them.

*Thread Reply:* For manufacturers with shitty model numbering schemes (read: Mitsubishi), you're going to get a lot of weird looks if you lead with the model number instead of the colloquial name or obvious identifying feature(s)

*Thread Reply:* M5-1052? ok, everybody knows that one, and as far as I know, Mitsubishi hasn't doubled up on that reference. Same goes for the MX-552 and MX-351.

But those are distinctly drafting pencils.

The second you step outside of drafting pencils, Mitsubishi's model numbering system goes all to hell.

*Thread Reply:* uni 5-1060 Flicker

*Thread Reply:* Very nice! Uni5-1060. I wonder what that makes the ¥700 variant—maybe Uni5-760?

*Thread Reply:* I have all those Flickers except the green one. I also have the BOXY variants with their cool silkscreen color scheme

*Thread Reply:* Uni 5-760 is correct. Good guess.

*Thread Reply:* I wonder what the 6 means in this context. Area of release? (Japan vs. international)

*Thread Reply:* 60 could be the development code for the Flicker mechanism?

*Thread Reply:* I'm kinda leaning toward that

*Thread Reply:* MX-351 and MX-552; with 5 in the second digit, perhaps that refers to drafting pencils

*Thread Reply:* same goes for MX-1052

*Thread Reply:* But then you have the M5-55, M5-56, and M5-57, and you're like 🤷‍♀️:skintone5:

Here's a black M5-55 (other colors are burgundy-ish and hunter green)

The price is fine, I've seen it more than double.

The design is almost identical to the 3- or 5- pencil set COLOR SHARP…

*Thread Reply:* I think it is identical. There are also black 0.3 and 0.5 versions that were sold as normal graphite pencils

Going… going…

コレクションからの放出になります。ペン類などのコレクションが相当たまりましたので少しずつ出品していきたいと思います。こちらは三菱鉛筆のダブルノッ クシャープペンシルになります。当時の小中学生にはシャープペンシルはちょっと高価な文具でしたがダブルノックというと一番テンションが上がるものではな かったでしょうか？カチカチやりすぎてすぐに壊したりして…こちらは文具店に長期展示品だったものです。当時定価700円芯は0.5㎜です。ダブルノック 機構、芯出しは確認しております。赤軸になりますが、赤は比較的女子向けのためかやや

*Thread Reply:* Ouch! How often do you all end up with pencils so worn from auctions?

*Thread Reply:* BKF won’t be helping that poor thing.

*Thread Reply:* True. I will sometimes buy a pencil which is a total dog if it is rare, cheap, and I don't have one. It takes some real thought if any of these is not true (evaluated left to right).

This color is fresh!

*Thread Reply:* I don't have a blue one. 🤔

*Thread Reply:* You know how many Kerry's I can buy for $100? 😂

Finally pulled the trigger and got this beauty.

*Thread Reply:* Looks like a best-of-breed specimen. Well done!

*Thread Reply:* This is really nice. There are a few of these on yahoo auctions right now.

Somehow, this kind of thing still happens. Only way to get it is through a proxy buyer in Japan who can get Japan-only items, tho.
