That Marblewood is NICE! Great works on here, thanks for showing us your addiction / hobby. Have you tried Brazilian Walnut (IPE)? I have a bunch of it around, and have been toying with the notion of doing the kimber's grips. How well do the ironwoods / extremely hard woods hold up to checking (for grip)? I have heard mixed things, most significantly: the wood is so hard that small portions of checking will occasionally chip off. Ever experienced that problem?
