Review on Carbide 4 Piece Engraving Woodworking Chamfer by Kevin Carr

Bits just aren't very sharp even though they're new. They tend to just crush my masking material instead of cutting it. But to make matters worse, the tips of the two largest bits aren't even blunt. So the last ⅛ inch or so is just... not the edge. I've spent quite a bit of time on some sharpening tools to improve them, but in the end it's just useless.
