Our standard wood handle materials include maple and box elder burl, farmed cocobolo, and birch composites (in cocobolo or grey/black colour). Other wood materials can be sourced for custom orders. We also use various semi-precious stones, antler and bone, including fossilized bone. We only use ecologically sustainably sourced handle materials. Our handle materials are stabilized (resin injected under vacuum pressure) by our wood stabilizing specialist, to minimize shrinkage, warping, cracking or discoloration over time.
