I'm interested in trying out straight razor shaving - and eventually if it's possible to get them sharp, for even one shave, it'd be an experience. I didnt want to spend a lot of money on a razor that I wasnt sure I'd want to keep... plus the fact that i'd also want a brush and soap... and strop (I found the kit rather attractive). I dont expect much from it - and I dont expect to pick it up and shave with it for a while... but I would like to try and hone it and see if I can get a edge on it that would even be marginal... or better. I know this isnt the best type of situation for a 'first shave' but I'm willing to give it a shot... if I like the feel of the method I think I'd invest in some real steel... anyway, on to the real questions.

What exactly are their issues? If it's the holding of an edge... how sharp can they get? sharp enough for my intended purpose? what makes their metal poor - is it to soft or too hard or is it full of impurities? I havent really heard any real explination as to why their blades are so horrible.
