these tools are almost unusable. There are tiny allen head set screws that hold the cutters in the handle they striped out the first time I slightly tightened them. That's not all, every thing in this cute little box are just toys. I'm new to leather work but I've been a master carpenter since 1980. I know how to use tools, but these are really of poor quality. If you want to get into leather working spend a little more and buy better quality, otherwise you might be discouraged by the sad results these tools produce.
A waste of my money.
