This item is discounted due to the following reasons and as the second photo shows, it is approximately 2mm shorter than the 90mm length, with a total length of 88mm. The individual differences 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 part of the red chisel. The photo shows a standard product for a 0.6mm curved engraving with a cemented carbide tip, using the handle of a red chisel No. 2 single-cut chisel. This looks like a red chisel at first glance, but it is actually a cemented carbide chisel made occasionally with a red chisel handle for fun. The handle is made of SUS for easy gripping, but the red chisel No. 2 seems to be easier to carve than SUS or all-cemented carbide due to the shape and material of this traditional chisel. I think the small step in the brazing part also has an effect. There is a gap between the red chisel and the cemented carbide, which seems to be good for people who find it difficult to switch to cemented carbide. The standard products have two types of handles, the red chisel, with the tip and the end of the single-cut chisel slightly shaved, and the blade size is about 1mm (No. 2 is 75mm). The cemented carbide tip is 20mm, 5mm shorter than the cemented carbide chisel with the SUS handle at our shop, and the brazing is about 5mm, and the total length is about 90mm, which is 5mm shorter for No. 2. The original paint will peel off due to the heat of brazing and shaping, so it will rust during the manufacturing process, so a rust converter (which changes red rust into benign rust and stops corrosion) is partially applied. You can remove it with sandpaper, but the paint is not very clean, so if you wish, I will cover it with a heat shrink tube. I have a video of me test-carving only one curve (I carved one and sold it). https://youtu.be/wf7VyuZ9mH0 At first, I felt that the bite was strong, and it became deeper than I expected, so the carving speed is a little slow. I think it's the difference because my own chisel has a strong buffing on the cutting edge. Also, the target is thin, so I often miss at first (I don't seem to be hitting the center with the usual SUS). The handle is a chisel, so it's a little more expensive, but since red chisels are sold for about 2000 yen, including the Nekopos shipping fee, it's a great deal.
