Ringed Gidgee

Gidgee: Acacia cambagei: One of the best woods for knife making, it tends to have a deep honey gold color with an incredibly well-defined, metallic-looking curl. Gidgee is also famed for its mechanically ideal properties, including excellent stability when exposed to moisture and fluctuating temperatures, incredible density that often puts it among the densest woods in the world and ultra-fine grain that allows it to take an excellent polish. Gidgee ranks among koa, rosewood burl and bloodwood burl as woods acceptable for show pieces and high-end working knives. The wood I have available is harvested in the deserts of Western Australia by a small independent saw mill focusing on high-end, sustainable timber.
