hi, i am looking at the cheness "yamakami" and the cheness "tsukikage" the blades are very fine, durability and sharpness is all there. but what about the tsuka itself? as a collector and an all around enthusiast of the Japanese sword, i know enough to unmount the blade,look at the tsuka for cracks,and inspect the mekugi pins before i cut. but seeing how i am not as experienced as some of you folks out there i would like some help. what should i look for on the tsuka of this katana?

thanks
