Looks like one of the German made Marble's when Jim Parker some how
used the Marble's trademark and stamp for a year or 2...back app. 1992 or so.
Benchmade also made a trailmaker for him back then
I have seen knives bout identical to yours but on the off side of the
blade it had Hubertus etched on it where it was made in Solingen, Germany
A Parker era Marble's knife is for sure my guess
