Here it is. Blade life you actually have to press to get them to cut. This has 100% nothing to do with this blade. In fact, if you push even the tiniest bit, the drill bit will get stuck and either gouge your piece of wood or injure your wrists from the force. I'm not saying it's a bad blade at all because it cuts through wood like butter, but you have to be very, very careful. Maybe I'm not used to a blade this sharp, but the recoil when hooking almost made me stop using it. The bottom line is, be very careful and very careful with this and it will fly through the tree. The beginning is the hardest part.
