Hi guys. This might seem odd and could be just coincidence but I have been looking for cheep tatty razors to do up on eBay for the past few months to feed my RAD and have noticed something a bit odd.

Almost all the razors I have seen with bone scales have very little rust or patina below where the blades go into the scales. I am wondering if anyone else has noticed this or if there is a reason for it. My first thought is that maybe the bone absorbs any moisture that happens to be aground the blade (within reason ofc). Here is an example of what I seem to keep seeing Vintage Cut Throat Razor | eBay

Has anyone got any thoughts on this ?
