    Um ... you sanded your washers and reduced their thickness by .01mm? That's 0.0003937 inch. What grit sandpaper did you use?

    That was likely either 2000 or 2500 grit automotive sandpaper. I polished the washers on a green-loaded strop after.

    I'm very careful with stock removal as I'm only trying to effect a very small change, CRKs already having been hand fitted to get the action just so. Once the stock is gone, it's gone and too much removed means a trip back to the mothership.

    I’m not a mechanical engineer, so forgive me if I’m not thinking about this correctly. But one of the selling points I always hear regarding CRK are the “tight tolerances.” If that is indeed true, and I believe that it is, wouldn’t that make them more interchangeable with to parts?

    There is still alot of hand fitting in the Sebenzas. Angle of the tang to the angle of the lockbar for example- for every .0005in of material removed from either if the angle stays the same, would result in a movement of the lockbar .006in or so.
    If you ever tour the shop, you will see that there is a surface grinder with a fixture on it for this task.

    Why? For me it's a voice that comes from my walnut brain:

    Me: "This darn Sebenza is stiff. The pivot is great but there just seems to be too much lockbar tension for my delicate thumbs"
    Walnut: "You takum two thumbs and shove that bar out...fixum problem"
    Me: "That's crazy, do you know how much this cost not to mention the skill and expertise that went into it's construction?"
    Walnut: "You bendum bar now"
    Me: "Do you remember the bicycle wheels that ended up in the recycle bin? Some jobs require special tools and measuring equipment...listening for the change in pitch when striking the spokes didn't work out so well for us, remember"
    Walnut: "oh yeah, maybe your right, and what about the Ford without the oil experiment?"
    Me: "Huh? we have a Chevy and put oil in it"
    Walnut: "You bendum bar now!"
    Me: "What about the wah wah pedal with the stacked resistor mod"
    Walnut: "What about it? It sounded glorious"
    Me: "It sounded glorious to us, but no one wanted to buy my wah wah pedal after we tinkered with it. Maybe we shouldn't mess with this knife."
    Walnut: "You stop talking, takum two thumbs, and fixum that knife!"
    Me: "ok, ok you win"

    So, I did it incrementally and carefully. Subjectively, I would say that I brought the tension down from a 4/5 to a 3/5. My delicate thumbs love it. I am able to smoothly sweep the blade out as I like. It still locks up at 50-60% with a good thunk. Blade retention in the handle is way more than any button or axis lock that I have, less than my back locks. Bending the bar took this knife from being just my best knife to my best and favorite knife.

    I probably never will, but if I sell it, I'll be sure to reference it as the walnut Sebenza!

    +3 points for inclusion of a wah wah pedal in a discussion about knives.
