The Irving Barber razors are just excellent. They shine with the AC blades and do a fine job with the injectors too. I did not care for using DE blades in it. They don't quite seem to snug up just right. They are hefty and well built. They feel as close to an actual straight in use as any shavette I have tried. The head geometry is good; tight and thin. It allows a shallower angle than a Feather SS. All the parts are interchangeable, and sold separately on the website. The owner is fantastic to deal with, and has helped me out with above and beyond customer service. The only downside I can see to them! Is I believe they are coated Zamak. I could see moving parts wearing coating down if it were a razor used daily over a period of years. It hasn't stopped me from buying two of them though. Considering they are priced at right about the same as an SS, and in my opinion a way better shaver, I totally recommend them.
