Doug,
I have several exotic woods in my "stash" that resemble yours. Maple burl...Spalted maple burl...Hackelberry and Olive wood. Your dimensions are large..."BUT"...(There's that word again)...If you want some handle "shaping" it'll help. Standard specs call for:

1 3/8" x 1 1/2" x 5"
Hope this helps, Capt. Chris
PS: Now...What's the wood?
