I picked up a couple of Viking Sword blades through the great blade exchange. I must say I really liked them. The blade I tried was very sharp and provided a reasonably smooth shave on the first pass. After 3 passes (WTG,XTG,ATG) the result was BBS. As a frame of reference, compared to the blade I used before it (Gillette Goal) the Viking was very sharp. After using the Viking I put in a 7 'o clock super platinum. I think they are very close in performance. The Viking might be a tad bit sharper.
The blade lasted the whole week which is my norm for good quality blades. I can't speak to price as it only cost me the price of a stamp to try it.
The bottom line....I am looking forward to using the one remaining Viking blade I have and will be shopping around to try and find them here in the states.
