I see a seller on the big auction site has 4 1st gen m390 4.1 blanks for sale and another person on the FB fanpage has an edc4 blank as well. All of them are ground w/out a sharpened edge or factory markings,handles or hardware. These [I am guessing here] were left over pieces not finished for whatever reason from the shop prior to the Idaho move. Anybody know what the story is on these and if there are other types as well? Just curious-
