i prefer a wood handle on my knives. i understand (and agree) with the concerns of shrinkage, etc. but, the look and feel of a nice wood handle outweigh those concerns for me.
i like the dense woods, for obvious reasons: ironwood, cocobolo and rosewood. i also am really starting to dig Osage. i know it has a lower relative density than what i just listed, but i really like the look. i don't expect any of these woods to crack under normal use. there will be some shrinkage, but i can touch them up.
with all of that said, i also do like the canvas micarta. and, i also like the burlap "mycarta" that i make (not to toot my own horn).
oh hey John. did you ever use those burlap slabs i gave you a while ago? i'm curious how they have held up.
