This first group are 52100 blanks hardened by Peters to 62 Rockwell. #1 and @2 are 42.5mm high at heel, by 240mm long, by 3.55 mm thick. Thickness allows for strong distal taper. $35 Each. 1 & 2 SPF! #3, 4 and 5 are 55.5 high at heel, by ~196mm long by 3.45mm thick. This is thick. I like the thickness to allow for a significant distal taper. $30 each. (#4 SPF!) #6 is 55mm high, by 180mm long, by 4.65mm thick. This is suitable for a Mioroshi Deba which was my plan, or a thick gyuto with significant distal taper. Sold All blades are rough shaped and can be reprofiled a bit as desired. All blades may or may not have a slight low or high spot. I always flatten on my flat platen and then mark center for grinding. Example of my western knife handle style.
