This is a listing for one graver with a specific title shape and size. The 105° and 75° hair-line gravers do not have images, but the image is close to 90°. Please refer to the illustrations. Image 2 of the bottom shows a single-cut and a 60° hair-line graver, image 3 of the whole shows a 60° hair-line graver, image 4 of the hand-held grip installation shows a single-cut, and image 5 of the engraver machine installation shows a 60° hair-line graver and a single-cut being used. Please be aware that 60° and 75° hair-line gravers are prone to chipping when used with a machine. Despite repeated requests, development took a long time. Because the cutting edge of the cemented carbide is extremely sharp, the cutting edge will easily chip if it is simply sharpened on a flat grinding machine, even with Japanese-style carving gravers. Western-style carving uses a prying motion and has a sharp cutting edge, so it is no match for it. However, this was resolved by slightly curving the lower blade during sharpening. Therefore, we utilized the Japanese-style carving sharpening technique and repeatedly practiced sharpening and test carving to commercialize the product. Furthermore, it is buffed with diamond paste (single-cut also has a mirror finish on the sides). The carving angle may be slightly higher than that of general Western-style carving gravers. The advantage of the curved lower blade is that the force applied to the cutting edge is distributed across the curve, making it less likely to chip and easier to bend. Also, the carving marks are clean because they are carved like a spatula. It is made from approximately 2.4mm round stock, and the length is 50mm before sharpening, which may be slightly shorter after sharpening. The size of the cutting edge has a strong taper value and also has different opposing angles, so it cannot be measured accurately, and the tolerance is ±0.1mm. M is around 1mm, and L is around 1.5mm, and there are also intermediate sizes. Except for the 60-degree hair-line graver, the diagonal line is about 1.5 times at 90° in the opposing dimensions. The trapezoid is the dimension of the lower blade tip. It can be attached to a chuck-type grip like a pin vise or a GRS set screw handle, but the handle's mounting compatibility is not guaranteed. In the case of this wooden grip, inserting 1 cm will make the total length about 11-12 cm. All photos are image reuse photos, so please understand that there may be some differences. Grips and scales are for installation reference only and are not included. (The cap is included) Initial defects will be handled, but chipping and damage after use cannot be exchanged. The width and angle of the cutting edge can also be adjusted during re-sharpening. http://bijodam.com/ Kobo BijoDam Yutaka Ota
