In order to do smithing work in the future, I bought it because I wanted to determine the hardness of cheap stainless steel blades etc at home that I will put on durability. Because of the narrow width of the Velcro which lids the case, may it be opened to some sort of beat when carrying it? I was a little anxious. Therefore, I put it in the paper box containing the case at the time of purchase, but because it is hard to put because it is thick because of the thickness of the Velcro tape I thought that this is a neck if it dares to use it every day, hardness check body There is no dissatisfaction with itself.

I think that it is the mast checker when judging whether or not the private beta can cut the material that I do not understand the feature. It reduces the risk of chipping or wearing down of the blade, and it is also useful for judging quenching after making your own cutlery. On the contrary, it can also be used to judge whether it can be annealed and shaved. I thought that it was high at the beginning, but that would save useless time and money.
