Whats the deal with these razors, are they better than western straights, easier/harder to use, sharper, are they still made today, or only vintage, and why do they seem to cost more than western straights, sorry for all the questions, but they seem to pop up on the bst and in the forums, and i dont know a thing about them, they look scarey and have no sclaes, so look a bit basic to my eyes?
