Looks to me like there is hone wear on the razor on the far left, and maybe on the yellow/orange handled razor on the bottom right.

You have to ask yourself if you buy the lot are each of the razors worth 1/4 the total? If not, are the good ones worth enough to pay for the bad ones?

It just my personal preference, but based on what I see in the picture, I would probably pass. I try to spend no more than $30 bucks on a razor, unless it is in fantastic shape. But, that's just me. Your method may vary.
