First of all I want to brag about the obscenly sharp edge I worked up on a 4/8 Engleswerks hollow. It was so sharp that it cut individual hairs from my arm with almost no linear motion and HHT at all points of edge. It cut like a cat using its claws! Just laying the blade on for starting an easy side-of- the- neck stroke, resulted in a nick! I must have had a minute tremor in my touch that did it. Never has this happened before. From there on it was a super light and well calculated shave! Perfect shave or BBS for sure. NOW for the unusual part: I had to finish the SHAVE WHILE HOLDING A TELEPHONE and carrying on a sensible conversation with an in-law. That my friends, took concentration! (Don't try this at home kids-I was lucky). All went well save that tiny nick at start. This is all a lot of fun. Learn and love this activity.
