It is sharp when you buy it, but it seems that sharpness falls sooner .... I thought that it would be possible for the stainless steel to be scraped because the object to be processed was SK 5, but I thought that it would be easy to understand if there were hardness standards to be processed.
We mainly use it for processing of platinum. Since it can be cut very smoothly, delicate modeling can now be done easily. The cheap goods less than half price used on caprice are moon and turtle. Also, the feel of grip is unexpected, very easy to hold.
