I take a chest hair (dry, no soap) and pull it tight. Then set your blade on the hair. When I do this it does not cut the hair.
Okay, stop right there. Others will correct me if I'm wrong, but this sounds like a dull razor. Dull dull dull dull dull. If my current shaving razor gets anywhere near a chest, arm, leg, head, or beard hair, the hair pops in half. The thicker the hair, the easier it is to pop. If you have to saw anything to get it to break, the razor is dull. I have shaved with a razor like this (see my earlier post, "can't get sharp enough" in the newbie forum) for 6 months and couldn't get the hang of it. Then I got a professionally sharpened one, and all is well.
