As a knifemaker, I prefer micarta. I can get it in just about any size/thickness. I can get different weaves for different looks (paper, linen, canvas). My shop only stinks for one day from the dust.
...as a knife user, I prefer G10 and carbon fiber. I hate working it, but love the finished products! You can't go wrong with the toughness of it. Virtually no temp issues, moisture retention or chemical incompatabilities.
Nice knife Joel!
Here's a black G10 handled one I did last year. I like the subtle pattern in G10.
