I've used Timors' in a Merkur Futur set at 2...they were smooth and sharp, better than a merkur and WAY,WAY better than Derby blades...The Timors' give me a close, smooth, irritation free shave every time.
I would put them as sharp as a Gillette sharpedge Yellow, but smoother for the first pass....only down side was I can only get 2 1/2 shaves from them.... So we can call that two shaves per blade, as I dislike changing blades halfway through.
My shaves are three pass affairs and I ditch all blades after three shaves anyway... Regardless of what they are.
