I got the 757 in the '90s, just as you see it. The 75 came ~15 years later, as an unfinished steel blank in a box of misc junk. Then 5 years ago I stumbled on about 30 pounds of fine-grained Micarta as slabs ~3/8" thick at an estate sale. A few months later, at a gun & knife show, met a local fellow who displayed his own work in one-off fixed blade sharps, simply an' lovingly crafted. Fell to chatting with him, mentioned the Micarta, an' my Western 75 blank. The upshot was a trade; he got the Micarta for the completion of the blank, straight-up, an used the Micarta I traded him for the scales. Took him about 3 months, as we agreed it was a spare time, no hurry project. The blank was already tempered to about 60 Rockwell, if I recall correctly. but there was no edge, an' aside from the hollow grind both sides, was only roughly finished otherwise. He suggested adding the red fillers, which I really appreciate. Note that the 757 is not hollow ground, though the pattern is very similar otherwise to the 75. His thought on where the blank came from was that when Western quit production, many of their patterns were bulk sold in the blank condition, an' mine was just one of those. My question has been why two nearly identical knives, save for the bevel grind? Or was the even the only difference? I haven't done any research about these; perhaps a few of you Western fans can fill me in. Thanks for lookin'!
