Low Budget Liner Lock

I’ve wanted to try my hand at making a liner-locking folder, but I’ve been putting it off due to the special material and tools that are needed. After reading The Tactical Folding Knife and a couple of tutorials, I decided to see what I could make with what I had sitting around. I was quite pleased with the results.

The knife is 3 1/4 inches closed, and it has a 2 1/4 inch 01 tool steel blade. I used .032 inch brass for the liners and maroon linen micarta for the scales. I had no idea how the brass liners would work, but it proved to have plenty of spring to lock the blade opened and to hold it closed. I made the spacers for the back of the knife out of 1/8” brass tube, and all pins are 3/32” brass rods. The brass rods fit perfectly inside of the brass tube so it worked out well. I also used the brass tube to make a busing for the blade and to make the thumb-bob which contains a 3/32” nickel silver rod. I made two stainless steel washers out of a double edge razor blade. (Double edge razor blades measure .0045” thick.)

All of the parts of the knife were peened together except for the nickel silver, which was soldered in the brass tube to make the thumb-bob. The thumb-bob was carefully peened to the blade. Because of the parts being peened, there is no adjusting of the knife now that it’s together.

This knife is not what I would consider a “high performance tactical knife”. I like to carry a small lightweight pocketknife with me everywhere I go, and this little knife fits the bill.

I hope this will be an encouragement to others who want to make a liner-lock but have been putting it off because of the material and tools involved.

That's a great knife, Chris, it's amazing what can be done with simple materials and tools.
 
This is a sweet little knife,I got to see it in person.THe pictures don't do it justice..
Great work Chris.

Very Nice! Looks like a handy little pocket knife that anyone would be proud to carry. And with the O1 I bet it slices like crazy.

You know, you're actually not far at all from what you are calling high tech and performance. Taps are not expensive or particularly hard to use and using screws allows you to take the knife apart. Pivot pins with screws are only $1.50 each, SS spacers from MSC are under a dollar each and torx screws will run you about $14 per hundred from Halpern Titanium. You can use SS for the liners instead of ti and that is readily available from the supply houses.

Can't wait to see more! :)
 
Chris, that's excellent, I always enjoy seeing your knives and am just counting the days until I get up the gumption to make myself one. Nice job!

Chris,
I think I said before I always like seeing your work, this is no execption. Very stylish and well executed.
One question: How is the brass working out as a material for the stop pin?
Great job,
Greg
 
Thanks all for the nice comments.

Ripper, the brass stop pin has worked out great so far. I've not done anything that applied strong direct pressure to the back of the knife, but I can open a letter like nobodies business.

That's a great knife Chris. I tried one a couple of months ago and as usual I wanted sturdy. I used hardened 5160 for the liners. Built a modified bolt lock. Milled races for ball bearings for the blade to ride on used a coil spring in the rear. It weighed about two pounds and looked almost square.:D
Pat yourself on the back for doing it right the first time. I may try another one now that I've seen yours.
