Gadget: Cutter Knives by OLFA or NT Cutter

Notes: When I moved to U.S., I was surprised to see my colleagues shaping cane with razor blades which looked very precarious. I grew up using hand-held knives what we call “sharp knife” or “cutter knife” in Japan. They are handheld knives with disposable blades with breakable sections (13). I found similar products here but blades weren’t as nearly as sharp. So, I used to have them sent from Japan or seek them out at Japanese bookstores in New York City. Thanks to internet, now I can order them with my heart’s content. One advantage of this kind of knife is that it’s far easier and safer to hold in the hand. Also, because the blades are narrower than safety razors, you can make a smaller radius that helps trace the “ears” (the top part) of the shaper tip far more accurately. I use the old blade for rough shaping, break off two sections, then finish it off with fresh sections of the blade. Shaping cane still requires a skill and concentration, but this type of knife should make your life easier.

There are two brands that are very similar: NT Cutter and OLFA. I believe NT Cutter is older but OLFA is more readily available here. Curiously, both companies are based in Osaka but I couldn’t determine their relationship. You can find OLFA knives and blades at OLFA site (olfablades.com) or from a variety of office supply stores. NT cutter products are also sold by many venders. Make sure to order the standard size knives not the heavy-duty ones.
