Generally easy to work with hand and machine tools. It planes well, though figured grain can cause tearout. Gluing and finishing are excellent.
Finish Recommendations
Wiping oils (like Tung or Danish oil) to enhance depth; lacquer or polyurethane for protection. Shellac is also excellent for bringing out the dark tones.
Notable Features
Distinctive mild, nut-like scent when working; contains juglone, which can be an irritant to some users; moderate natural luster.
