Good confirmation for me that a thin blade is the best. I have an old simple saw with a 4″ blade. I have cut many piece by just holding the stone somewhat loosely and rocking it back and forth. You can feel the tendency to bind. Almost never does. Almost. The stone flew off and the blade bent slightly, but I messed with it and I still use the blade. Question is, for me, what to do with cuts that are, say, more than 1.5 cm. It is hard to have that “safe” feeling when the cut gets too deep. Any suggestions?
