About Yellowheart
Vivid canary-yellow that holds color well; hard and dense with fine texture.
Yellowheart strikes a good balance between workability and durability. It shapes and drills easily with standard woodworking tools, takes a smooth finish without tear-out, and feels comfortable in the hand — not too heavy, not too light for full-tang knives.
Stabilization & Treatment
At 1,790 lbf Janka, Yellowheart is dense enough that stabilization isn't strictly required. The wood handles moisture and daily wear well on its own. Stabilized versions are sometimes available and add an extra margin of protection, but raw Yellowheart scales have a strong track record on working knives.
At ExoticScales, we stabilize using Cactus Juice resin — the same process used by professional scale makers. Each piece is cured under vacuum and heat, producing a hard, sealed blank that machines cleanly and takes a beautiful finish.
Available at ExoticScales
Yellowheart scales are available in 5" × 2" × ¼" and 5" × 1.5" × ¼", fitting the vast majority of full-tang knife blanks. We carry matched pairs and — where the grain allows — bookmatched pairs. Highly figured and one-of-a-kind pieces sell quickly.
