Sounds like a waste of a nice knife, amazing how some people mistreat (or downright abuse like here) their tools...sharpen on cement? You have got to be kidding me.
I wouldn't say "a waste".. It apparently did it's job for a long period of time.
Abused, yeah, I can go with that..
I have a 10/99 Microtech kestrel, I saved from the first owner. Had to sharpen out, live wire ark's, from him cutting wire..
But used it daily for 7 years, in construction. But I can spydie flick it open, by the thumb stud, now..
The action was cared for, but the blade was used like the OP's dad..
Sharpen on concrete... What's wrong with that?
I've put shaving edge's on with concrete, rocks, the sides of cinder blocks, rusty metal handrails, the backs of shovels, etc.. Whatever gets the tool, back to sharp and doing its job.
After I got my SM, I gave it some edge love..
Closer Spyder, to that kind of use, is my OG Manix in Foliage Green
If you can sharpen, it doesn't matter what you use..
Hell, even with the Sharpmaker, I only use the diamond rods and strop..
I think many of us lose sight of the fact these are tools. If it's sharp enough and gets the job done for years at a time, what's the problem?
We're afficianados here, so we buy knives for a lot more than just work, but disdaining those that don't is just silly. I'm guessing that knife has done more honest work than the majority of our collections combined. Personally, I think that's something to admire.
Highly agreed and well put.
