Rare, discontinued vintage Cold Steel USA large Trail Guide pocketknife see/read For Sale

This is a rare, discontinued vintage Cold Steel large Trail Guide lock back pocketknife. It has a Carbon V (proprietary steel similar to 1095 with added vanadium) blade a bit under 4" long (including the ricasso) heat treated to a hardness in the vicinity of 50 to 55 HRC. It has a black polymer handle with a steel pocket clip. It has been lightly cleaned but not polished and lightly oiled with Japanese camellia oil made for knife and tool maintenance. It has light wear including some light oxidization, but no remaining active rust as far as I can tell. It is mechanically sound and tight. Any further maintenance is left up to the buyer.
