Hello, I am both new to the forum and fairly new to leatherworking. I just got back from a trip to a local Tandy Leather Factory with some leather scraps and some tools. Right now I am trying to cut a hole about the size of a quarter in leather that is thicker than my belt. But its really thick, and the utility knife I am using just wont cut a neat enough hole. I was thinking of getting one of those drill bit attachments, the kind that lets you cut a round hole in wood, or something similar. But I would appreciate any advice, Thank you.
