So named for ambrosia fungi, which is found in association with ambrosia beetles. The beetles bore into the trunk of the tree, bringing with them the ambrosia fungi, which subsequently stains and discolors the surrounding wood. The discoloration can be very similar to spalted maple, though with ambrosia maple, the discoloration is centered around the boring paths of the beetles, and their entrance holes can usually be seen.

I was told by a long-standing customer that his 7-year-old knife was, "like new." I asked, "How can that be?" He said, "Because I take care of it!" So, I encourage three things; (1) it is sharpened. You keep it HONED! (2) Blade is friction fit (channeled) in the sheath. Reinsert the blade in same spot you extracted it. (3) A little mild soap and water, rinse, and wipe dry.
