Has anyone else gotten a Stay Sharp 344 sharpener for one piece 3 blade heads? Mine came in yesterday, but all I had on hand was a Sonic from 20 years ago, and a cheapo off amazon. The cheapo is bad metal and edge just rolled with the new angle. The sonic would grab nail, but wasn't quite shaving sharp. Has anyone tried one yet with a quality head? I've been debating getting a pack of M3s to mess around with, but MIM still makes me flinch... guess I could order some VPAs, but before doing that I wanted to see if anyone else had luck with it. So far I'm not convinced, but I don't have a good quality head to really check.
