Dismanteling an inexpensive Frost tactical liner lock

It's raining. My wife went to a womens church luncheon. .. So I decided to take apart an inexpensive Frost tactical liner lock. I thought this would be a good way to practice on replacing handle scales without risking a good knife.
All the torx and Philips screws on the plastic handles were easy to remove, but how do I get the blade swivel apart? The knife has an adjusting wrench for tightening the the swivel, but I've loosened it quite a bit and the two sides stay together. Will I need to pop off one side and sacrifice the swivel mechanism?

Never mind. I finally got it off. The pivot pin was all one plastic piece. With a small pair of needlenose pliers on one side and the knife's wrench on the other it finally snapped. Now I can order a new metal pivot.

Should I use the old plastic washers or get brass ones?

Sorry for the posting that shows my lack of experience.

i am not familiar with that knife but if you can get brass or bronze washers in the correct size, i would replace the plastic. can you post pics of the disassembled knife?

Johhnie is correct. I would replace the teflon with bronze phosphorous and there are many good pivot pin assemblies. There are many good websites and catalogs that will carry these parts and you will end up with a smoother opening and closing knife. You do need access to a pair of calipers to get the right parts.

My answer is generic for all knives of that type, I'm not familiar with Frost liner lock.

GOOD LUCK!

Thanks for the helpful suggestions. The Frost Cutlery Tactical Fighter (#15-867B/B) is an inexpensive knife made in China. I got it as a door-prize a few years ago. I'll post a photo of the parts. It looks like I'll need new liners because the originals were set inside the original plastic scales. I think I'll make liners out of some plastic that will match the dymondwood scales I plan to use. This is learning project, and the parts I buy will probably be worth more than the original knife. Sorry about the photos. I haven't figured out how to take good closeups yet.

i would use the original steel liners if i could. they are in good shape.

Given that the original liners are smaller than the original scales and the liner-lock piece, how would you do the edges on the new scales? Thanks for the feedback.

make your new scales the same size as the originals and go from there. or get some sheet brass or steel and make new larger liners.
