Workability
Generally easy to work with both hand and machine tools, though the pronounced difference in density between earlywood and latewood can sometimes cause splintering or uneven planing.

Accepts stains, varnishes, and paints well, though pre-conditioning may be required for even stain absorption on softer earlywood.
Notable Features
Known for having a high strength-to-weight ratio, distinct resin canals, and a characteristic resinous scent when freshly cut.
