Because it is expensive, it is used exclusively for super tensile strength steel plate. Certainly as the product name, I think sharpness is wonderful. On the other hand, it is extremely brittle, the cutting edge cracks at the first use, and the end is also frequent. It will be totally meaningless and sad if spot cutters with 6000 yen each do not work just by scraping several times.
I think that this is the best if you are using BIGTOOL's spot polishing machine. Sharpness is very good. The dissatisfaction is easy to temper with continuous use, and the shape of the cutting edge is special and the edge of the cutting edge is easy to break, improving sharpness. It is very easy to use because sharpness is good, but sometimes it is necessary to pay attention to usage somewhat.
