This is a single item listing for a cost-reduced, trial version of a tungsten carbide scribing chip, instead of all-tungsten carbide scribing chisels or chisels with handles. I've made prototypes in 4 sizes, starting with 0.2mm. Images 1-3 use the 0.2mm chip. For sizes smaller than that, please refer to image 4. As this is a prototype, image 4 shows actual photos of the sizes being sold. Naturally, these are made by machining the highest quality, domestically produced tungsten carbide. The difference in quality between domestic and overseas tungsten carbide is significant. These are, of course, made in Japan. Cheap imports from overseas often have questionable material specifications. For example, tungsten carbide is different from tungsten. To put it simply, tungsten carbide is tungsten alloyed with cobalt. Some products use vague terms like "super-hard metal." Japan has the highest standards for tungsten carbide, and the industry is small. There are few, if any, experts in sharpening tungsten carbide blades in Japan besides myself. Like my scribing chisels and chisels, these are hand-cut and polished with a gentle taper. Blades with a straight-width edge, cut mechanically, will break from the base and become disposable. The shorter the blade tip, the easier it is to break. The gentle taper works on the same principle as a fishing rod, gradually transferring force to the base. In other words, it bends like a fishing rod, making it less likely to break. (I am not saying it will never break.) Like a fishing rod, if it breaks during scribing, it's often just a few millimeters from the tip. Even if it shortens a bit, it can often be reused after re-sharpening. Of course, after-sales service for re-sharpening the blade is also available. This level of sharpening is extremely difficult for users to do themselves. The total length is approximately 25mm. Depending on the size, about half of that length, or about 15mm, has a rectangular tapered shape. For attachment, the round material will be approximately 1.3-4mm in diameter, so you will need a pin vise or similar tool that can secure a 1.3-4mm round material. The blade tip has a mirror finish at the same angle as my scribing chisels and scribing chisels. The tip is marked with a marker to indicate the front and back direction of the blade. The color heat shrink tubing is used for size identification and as a stopper when attaching to a pin vise or as a cover tube. It may move if pressed hard. As this is a prototype, it is undecided whether to relist or add it to the lineup. http://bijodam.com Workshop BijoDam, hosted by Yutaka Ota
