Perhaps their most famous invention is the rollerball pen, and they designed the first one way back in 1964. They were the first company whose pens had a tungsten carbide ball and manufactured a transparent refill where the amount of ink remaining is clearly visible. You can find out more in our guide, The Top Ten Drafting and Mechanical Pencils. The OHTO Super Promecha mechanical pencil is considered one of the best drafting pencils in the world. About OHTO & Interesting FactsĮstablished in 1919, OHTO is a Japanese writing equipment manufacturer that is renowned for its innovative designs. If you like the OHTO Minimo mini mechanical pencil, OHTO makes a matching Minimo ballpoint pen with a needlepoint tip. They supply a convenient credit-card-sized holder to store it in diaries, journals, notebooks, etc. We can now insert the new lead into its barrel via the hole that the cap was covering.īecause of its tiny size, it could be easy to lose this pencil, but OHTO has even thought of that. Hold the barrel and its cap, gently pull the lid away from the tube to refill the pencil. If you inspect the push button, you see a small cap covering the end of a metal tube. Pressing the pushbutton will advance its lead. The pencil has a fixed 1.4 mm lead sleeve. OHTO Minimo Specificationsĭespite its small size, it is reasonably easy to write with, although I wouldn’t want to do it for long periods. It is only 1.5 mm thinner, but it makes the Pilot Birdie and the Zebra TS3 look quite chunky in comparison. I instantly noticed that the barrel diameter was far smaller compared to the other two pencils. It is the world’s smallest mechanical pencil. If one can find refills, they will have a pencil they can take anywhere for a very long time, even if it’s not their main utensil.The OHTO Minimo Mechanical Pencil is simply an engineering marvel. It isn’t perfect, but it’s a tough little thing that gets the job done, and for an inexpensive price, considering the materials and drafting-friendly capability. It’s a great pencil, really, and it lives up to the expectations of its ballpoint relative. One would just have to worry about the pipe getting bent or tearing something. And its rugged steel exterior make it great for taking anywhere. The pipe and the lack of a shock absorber do make this pencil much more like a drafting pencil than the standard mechanical pencils, and it would work in that scenario in a pinch (or perhaps a bit longer). It is a bit hard, and brittle at times unlike many pens there is no shock absorber, so keep the lead as short as possible. ![]() The lead feeds well, and writes as smooth as one would expect a standard HB to. Removing the eraser reveals the lead feed, which thankfully does come with more than one lead in the standard version. The push cap operates smoothly, and can be removed to reveal an eraser that does its job, though it has no replacements in the package. Unscrewing this will reveal the lead and make it breakable but otherwise not change the operation. ![]() The real difference between the two bodies is that after the section the pencil has a black plastic taper with a metal pipe for the lead. The grip section is plastic with a bit of “knurling” that provides some grip and is unintrusive. The barrel is also a nice, plain stainless steel with the pencil’s information printed on it. ![]() The body of the pencil is the same as the pen, starting with a sturdy stainless steel click button, and going to a black plastic clip “holder” for a stainless steel clip that does its job if one doesn’t get turned upside down and shaken. Is it as good as its counterpart? Let’s see. But Zebra has several other writing utensils in their “301” line, one being the still-very-popular M-301 Mechanical pencil. I’ve used one for a long time, and they have a good record for staying together. The Zebra F-301 is one of my favorite and most hardy ballpoint pens. ![]()
