I am finally around to testing different blades on my face after getting used to enough technique that I can shave every portion of my face to BBS and my neck and chin to a DFS.
Lately I have really been enjoying the red Personna blades, finding them both sharp and smooth and quite compatible with my technique. Today I decided that I would unwrap one of these that I have in my DE blade tray
I lathered up with Proraso cream after a hot shower, popped a Derby into my Merkur 34c and went to town. I shaved the usual WTG, XTG, then a final XTG or ATG for my face.
I also shaved my neck WTG then XTG, usually I don't venture any further than this or I get irritation.
My verdict? the blade doesn't seem to be any difference in sharpness to the Personnas, however DAMN! it felt so smooth almost as if it wasn't touching my face. This was a double edged sword (no pun intended) as it made me feel that I could get away with an ATG or XTG 3rd pass on my neck to make it closer to a BBS finish.
... I was wrong, decent amount of burn and 2 weepers after applying some balm, but its all gone now, fantastic shave I just received though from them, I Think I will be buying a bulk load of these to include in rotation with a bulk load of Personna Red's !
