I`m the new owner of Velitrius' old Mini Tac. It isn`t chisel ground. I just brought it to work today and cut up some cardboard with it. It really is a nice little cutter. It performed better than I expected. I think the thin stock really helps it glide through cardboard with little effort. I`m thinking of taking James M`s suggestion and use it in the kitchen for a while. Maybe I have a new paring knife.
