Silvan asks:

Don't know if it's the same species you've got around the house--Buxus
sempervirens. AKA Turkey boxwood, Abysinian Boxwood, Circassian boxwood.
Grows in Europe, North America, and western Asia. Tree grows to a height of
20-30 feet, max. Anything over 8" diameter is nearly impossible to find.

It is supposed to go up to 40 feet in the right spot, but good luck finding
it! Buxus sempervirens is not native to the America's

Chisel handles for heavy use (mortise chisels) around here were either
boxwood or hornbeam (Carpinus betulus). The latter is still used. I am sure
Blue beech (Carpinus caroliniana) and hop hornbeam (Ostrya virginiana) would
do well also. For a bench chisel there is no end of suitable woods.

I'd keep away from ash for something that will be handled often.
