Yep, I have checked out the Osborne and Tandy punches, I already had a few of their round ones, but they don't have oblong ones that length, only oval ones which wouldn't match. I haven't tried those yet, but I realize now they should work great too, at least for rounded buckle tongues.
I just wanted to know if there were any oblong ones, i.e. with a straight line on each side of the length between the two rounded ends, not an oval shape. I searched other leather tool distributors but couldn't find any, which seemed strange to me since oblong seems to be a common shape in commercial belts.Maybe it's a recent way for the brands to distinguish themselves from the competition.
Thanks anyway, Chief!
