Hey Been a while since I've posted. Just have a couple questions. I have a few blades that need some sharpening. Assembly so I can seem to get a super clean razor edge on where I can push cut paper other blades I just can't seem to get that kind of cutting edge on them. For instance my tops knives CAT & Baja 3.0. tomorrow night work on them They just will not cut cleanly through paper. Is this user error or is it edge geometry? I know these blades are designed for everyday utilitarian style work. I have a blunt force blade that is about 8 in long very heavy but cuts paper with ease and will shave my arm no problem. Any tips or info would be greatly appreciated.
