I used some 1-72 screws in the Micarta handles on my AL Mar Falcon Ultralight to most a clip. The three screws hold the clip very securely. I've bent the clip several times and the screws didn't budge. I used a bottoming tap.
I use a Ontario Field knife that I modified. I thinned the blade a little, added some belly to it and remade the handle. It is 1095 steel. Works well for a GP knife that I've also use on frozen meat and veggies, batoned it through frozen chubs of ground meat with out any problem.
I've had a Grizzly for along time. I think I took a file to the drive wheel to give it a little crown to make it track better. I'd try disduster's electrical tape wrap to see if an increased crown helps.

If you have screws of a known pitch, you can use them like a pitch gauge. Be careful, there are some metric sizes that are very close to SAE sizes. Example: 1-72 and M2 x 0.4
4-48 and M3 x 0.5
A lot of computers and electronics use metric screws which may be another source.
My wife got one of those Pampered Chef ones that don't leave a sharp edge. They work OK. I still keep a P-51 in the drawer for that occasional stubborn can.

When I worked in San Francisco, there was a building materials recycling place. They would recycle and resell used building materials. I got some birdseye maple flooring pieces for cheap, also some walnut, sugar maple and ipe for cheap.
