I can't state enough the value of the wiki and the input of the experienced members here are.
I received my brand new Master USA straight razor in the mail today from Ebay, complete with it's 440 stainless china blade. Honestly it can't even cut paper.
The blade is not the only point of failure in that the scales are pretty loose so that the blade flops in and out freely.
Also the heel of the blade comes out just beyond the scales when folded up so that if it were sharp it would be a danger to handle.
The blade is almost straight but not enough to keep it from smacking the scales when folding.
I read in a post that XMAN used butterknifes to practice shaving before his gear arrived, that's about all one coud do with this blade save for try to look menacing I guess.
