Not my knife, but belongs to a Deacon from our church. He wanted to see if I could sharpen it for him.
It is a CRKT Desert Cruiser.
I noticed right off that the blade sat off-center in the well, scrubbing hard against the liner. Also it felt a little "off" when opening and closing the blade (I don't say 'walk & talk, since it has no backspring - it is a tactical friction folder).
Once I took it apart I found some sticky coffee or cola inside, which had caused enough friction to slowly back out the main screw.
This knife was a joy to take apart and reassemble. There were no annoying springs or bearings to fight back into place - only a couple of thin plastic washers. After some soap & water, drying & oiling, it worked like brand new.
I sharpened it freehand with a whetstone, and finished with ceramic stones. This knife has some HARD steel! It took quite a while to get an edge on it, but it shaves now!
I am not really into tactical folders, but this is a pretty great knife!
Jesus is life.
Everything else is just a hobby.
