This listing is for one graver with a specific shape and size. Please note that you are selecting the shape and size, and this is not a multiple-set listing. m(__)m The main image shows examples of different shapes and sizes, including hair-line and single-bevel gravers. I, myself, have developed and individually crafted these gravers, inheriting three generations of history from the carving artisans of Kofu, the city of gemstones. I combine mass production techniques with the hand-polishing skills of a craftsman, and I finish the cutting edge with unique techniques that cannot be imitated. The SUS304 handle is 5 x 3 x 75mm. The cemented carbide tip is 25mm long, with a 5mm brazing allowance, making the total length approximately 95mm (with individual variations). It's a bit thick, but it's a flat rectangular bar, so the corners are appropriately shaped. When carving, you bend the graver based on the shape of the cutting edge, and you carve while feeling the horizontal with your fingertips on the handle, so it's better if it's not round. The polishing of the curved cutting edge involves changing the angle, so it becomes slightly rounded. The high-speed polishing of the cemented carbide's boat-shaped bottom (only the rounded part is hand-polished) is a multi-faceted cut like a fine mirror ball, just like a diamond, so the final finish is done with diamond paste. Slightly blunting the corners with the paste also improves the curve. Especially with blades that are simply polished with a straight diamond grinding wheel, like mass-produced items, they will catch and can cause damage. If you try to carve without breaking the blade, you can only carve shallowly. It is said that you are considered a master when you can successfully sharpen a graver like this, so it also serves as a sharpening example. Please refrain from purchasing if you intend to use it as a disposable tool. m(__)m When re-sharpening, you can also adjust the width and angle of the cutting edge. Furthermore, the sides and bottom are also finished with a single-sided mirror finish. Especially with single-bevel gravers, you carve mainly with the corners of the sides, so side polishing is a great advantage. However, the surface that you look at is difficult to see, so it is not mirror-finished. In addition to curves and straights, there are various angles and shapes of the cutting edge. Refer to the illustrations; if nothing is specified, it will be the standard shape. The images are reused from multiple sources. ※For engraving only! Requires skill in carving. There is a video on YouTube of me actually carving a arabesque pattern. https://youtu.be/jMO47Hfh1ko Here's the difference between straight and curved carving with a single-bevel graver: https://youtu.be/7Z9wDasbCcU Cases are included for sizes 0.7mm and larger. http://bijodam.com/ Kobo BijoDam Graduate of the Japan Jewelry Craft Carving and Engraving Department, CGL DC, Yutaka Ota
