1988 VINTAGE BUCK 188 / PHROBIS III M9 Knife and Sheath

I have a  Rare Vintage Buck #188/ Phrobis III M9 knife and sheath ( no box or papers). The knife is in good condition.I bought this knife some time ago but never did use it. I am the second owner of this knife. One can see in the photo with the red circle that the knife was probably used to cut wire (my guess). Other than that nothing else is wrong. The blade is 7",  Overall length is 12.25". Price is $800 shipped. $750 picked up in Vaughan.
