My son gave me this knife, a CRKT M16-04 Z, a few weeks ago. It had two nicks. I just got it back from Papaw. He put a new edge on it and got it razor sharp. He said it ought to keep its edge well. The new edge gives the blade a slightly different shape.
But it was still dirty on the inside, so it was time to disassemble and clean. I got a star driver set a Lowes for six bucks. Here's the first partially "exploded" view.
I almost missed that little o-ring under the main screw.
Here it is a little further along:
I've got the gunk cleaned out. I used brasso on the metal parts then rubbed on some light oil.
Here's the start of reassembly:
All back together and looking a lot better:
I didn't have any loctite for main screw. It looks like there was some kind of blue bonding material on the threads. I'll be picking some up soon to finish the job.
