Mesquite Board M-1010
2.8"x 1.4"x 5.8"
This unique Mesquite board has a swirl of grain colors and textures. I'd say it's about 70% heartwood with 20% sapwood and 10% bark, where the bark itself has been removed. This leaves some nifty looking frass-filled holes that cross-cut the grain (front photo).
I see no cracks, checks or other structural flaws.
