This is a prototype of a cost-reduced, all-carbide line engraving tip, not an all-carbide line engraving chisel or a handled chisel. The photos show the actual product. Naturally, it is made by cutting out the highest quality domestic carbide. The difference in the quality of carbide compared to overseas products is significant. Naturally, it is made in Japan. Cheap imported products from overseas have questionable material specifications. For example, carbide and tungsten are different. To put it simply, carbide is tungsten alloyed with cobalt. Some products have ambiguous descriptions like "super-hard metal." Japan has the highest standards for carbide, and the industry is small. There are few, if any, experts in sharpening carbide cutting tools in Japan besides myself. Like our line engraving chisels and chisels, it is hand-cut and polished with a gentle taper. If the blade has a straight width cut mechanically, it will break from the base and become disposable. If the blade tip is short, it is even more likely to break. A gentle taper works on the same principle as a fishing rod, gradually transmitting 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 line engraving, it is often only a few millimeters from the tip. Although it will be slightly shorter, it can often be reused by re-sharpening. Of course, after-sales service for re-sharpening the blade is also available. This level of sharpening is extremely difficult for users. The total length is approximately 25mm. Depending on the size, the tapered rectangular cross-section is about half that length, or about 15mm. The attachment is a round material with a diameter of approximately 1.3mm, so a pin vise that can secure a 1.3mm round material is required. The blade tip is mirror-finished at the same angle as our line engraving chisels and line engraving chisels. The tip is marked with a marker to identify the front and back directions of the blade due to the tip design. Also, the color shrink tube is for use when attaching to a pin vise, as a stopper for the cover tube, and for size identification. It may move if pressed hard. Currently, it is a prototype, so it is only 0.2mm, and it is blue. Due to being a prototype, it is undecided whether to re-list or add it to the lineup, but I have made four sizes as a trial, so I will add images. http://bijodam.com Hosted by Workshop BijoDam, Yutaka Ota Type...Tools
