Thank you!
This is very interesting information,
I never thought in this direction.
Push-cut, is this when cutting pressure forward and down, without sawing motion?

I have the whole left hand in a lot of cuts. When I cut something, it does not succumb, I add pressure and then bang!
Resistance falls briskly and knife slams into the hand.

It does not matter, there was a knife with or without a guard. The thing is that I often forget about safe working techniques when nothing is on the blade path at an imaginary failure.
