well, it's obviously not AS corrosion resistent, but I doubt anyone will have any rust problems. even if you use them for three or four days straight. idk though.
I think doublecut finishes are smoother like satin finishes,(so it will cut and slice better) but more protective than a satin finsish.(even though not as corrosion resistent) even the uncoated 5160 and 1095 I have doesn't get rust and a bead blast can't be THAT much more prone to rust. I don't normally have rust problems with knives anyway though so I guess I can't really say for sure, but I don't think I will have any problems. I hope I can get it though. <img src="/ubbthreads/images/graemlins/frown.gif" alt="" />
