Oh wow cool. I didn't know about the Buck. Hrm, I'd rather have the Buck, it seems. I wasn't aware this was a copy of something. Dern, learned something new. I will have to get the Buck, and this copy may disappear into the for sale eather Charles.
I have some Sheffield PST / original Supertool knockoffs. They are surprisingly good for off brand -- thick tool stock, real phillips head, etc. Honestly the files are better than most files I see on SOG and Chinese Gerber. I personally hate the Buck multitools, I find them very awkward. What a weird design to copy.
