I haven't carried this knife is a few yrs. Matter of fact I just found it last week in an old coffee can in my sons room. I was letting him use it for stage craft work which is what he does. Kind of forgot about it really until last week. This is the large model and the small model I purchased shortly after the initial purpose was with it too.
Needless to say these things were beat. Dull as butter and tons of blade play. Nothing else to do last week so I reconditioned the large one. Truth be told I couldn't get that mammy jammer sharp to save my life. Didn't use the Lansky diamond set I have just cause it is so difficult for the clamp to get a bite on the blade. Well I am pretty decent at free hand sharpening and could only get the blade so so. I mean it would shave hair and all but just didn't seem like the way I had it when I gave it to my son. Frustrating to say the least.
First thing I did was disassemble the knife and cleaned the snot out of it. Lint and dirt along with little tiny pieces of wire from coax I think or speaker wire. Got that taken care of in nothing flat and then proceeded to the sharpening. Talk about an excercise in frustration. So I broke down and took it to a local commercial sharpener. Picked it up last fri. and was pretty surprised on what appears a bit more off the edge than I thought. Still though it accomplished what I wanted to do and that is get it sharp.
It now has a pretty high polish on the edge and would easily shave hair. But still from I remember it was just not what I remember it to be. I cut up some newspaper tubing, etc. and opened a few boxes and worked on my old carhart jacket that I use to train with sometimes and to test edges. Pierced fine but just didn't have that pizzazz I like for the edge to bite. I am no martialist when it comes to knife training either just do stuff that is simple and repeatable without alot of complicated handling maneuvers. Well just happened to pick up a small soft white stone from Wally world over the summer when I was in Mont. Took the KFF at a very high angle to the stone maybe I would guess +30degs on each side for a couple of passes and voila. I was hesitant to do this as I figured I would ruin the highly polished edge on it. Well I didn't and it now has bite up the ying yang and no discernable burr to it. Course it didn't have a burr that I could see or feel to begin with.
The only other thing I need to accomplish is to keep the pivot from loosening up like it does. You can just flick it open with your wrist but it has 0 blade play in any direction and it passes the spine whack test big time with flying colors. I have put teflon tape on the threads for the pivot screw and that doesn't seem to help. It just loosens up. I have also used bowstring wax after taking the teflon tape off. Will try loctite next. Just wanted to let everyone know that for the 40 bucks this thing cost 3 yrs or so ago and the beating my son put it through the darn thing has held up very well. I might have a machinst friend put some nicely chamfered holes in the frame and slabs to make it lighter in the pocket though. Keep'em sharp
