I bought my first new Buck 110 this last spring. Idaho stamped. Blister packed. I recently had occasion to use the sheath which came with the new knife as my old one had the belt strap break. (It was over 20 years and 200,000 miles and had as much abuse as the knives it carried.) When I took out the knife to use it a few hours later I noticed a black gummy residue on the side of the handle. When I looked to see where it originated I diiscovered within the new sheath, a 'patch' of black material goo-ed over the inside of the metallic snap. Due to the tightness of the sheath the patch was pushed down allowing the goop to transfer to the knife. I don't get all freaky about scratches and marks from the snap, but someone must have, so now I have goo instead. :grumpy:
