So it’s not a Gem. Well I’d be goood either way. PTFE blade is a favorite of mine and in the AC format I like the Proline so AC works and the only small negative I can see is for example using a ATT SE2 it doesn’t have the maneuverability of let’s say a DE, Gem razor like the Sabre or an injector. Of course that’s just my opinion and experiences with all the different formats. BUT and that a big but Andy seems to have created something very special with the P 17-4 so I’m thinking he’ll nail the AC razor to. Again thanks for the info!
