This item is discounted due to the following reasons and the fact that it is approximately 2mm shorter than the 90mm length shown in the second photo, now measuring 88mm in total length. The individual variations in the cemented carbide tip, brazing, and handle are within a tolerance of -1.5mm to +2mm overall. The shortening is mainly in the handle portion of the red chisel. The photo shows a standard cemented carbide engraving chisel (0.6mm curved engraving) adapted to the handle of a red chisel No. 2 for single-sided cutting. This looks like a red chisel at first glance, but it's actually a playful creation using a red chisel handle with a cemented carbide chisel, which I occasionally make. The handle is made of SUS for easy gripping, but the red chisel No. 2, due to its traditional chisel shape and material, feels easier to carve with than SUS or all-cemented carbide chisels. I think the small step in the brazing also has an effect. There's a gap between the red chisel and the cemented carbide, which might be good for people who find it difficult to switch to cemented carbide. The standard products have the red chisel handle, with the tip and the end slightly shaved, and come in two types with blade sizes around 1mm (No. 2 is 75mm). The cemented carbide tip is 20mm, 5mm shorter than the cemented carbide chisels with SUS handles at our workshop, and the brazing is about 5mm, making the total length about 90mm, which is 5mm shorter for No. 2. The original paint peels off during the manufacturing process due to the heat of brazing and shaping, so it rusts. Therefore, a rust converter (which changes red rust into a benign rust to stop corrosion) is partially applied. You can remove it with sandpaper, but the paint isn't very clean, so I can cover it with heat-shrink tubing if you wish. I have a video of me test-carving a single curve (I carved one and sold it). https://youtu.be/wf7VyuZ9mH0 At first, I felt the bite was strong, and it went deeper than expected, so the carving speed is a little slow. My own chisels have a strong buffing on the blade, so I think that's the difference. Also, the target is narrow, so I often miss at first (with my usual SUS chisels, I don't seem to be hitting the center). The handle is a chisel, so it's a bit more expensive, but since red chisels that have been sharpened are sold for around 2000 yen, it's a great deal including the Nekopos shipping fee. Cases are included for 0.7mm and larger. BijoDam Workshop, Head, Graduate of Japan Jewelry Craft Engraving and Setting Course, CGL DC, Yutaka Ota
