Seeking low-tech solution to improving the edge on a machete or sword

Have you done much/any sharpening before? There are loads of YouTube videos on sharpening, have you looked on there yet? Most of all stay away from the angle grinder, please

 

Yeah, stay clear of the grinder... Please... :thumbup:

 

Have you tried using Sandpaper?

 

I'd do some research on YouTube to learn proper sharpening technique. YouTube is an amazing resource.

If you try to sharpen using sandpaper, you could try setting the bevel using 200 grit paper, then progress up through the grits until your satisfied. Something like 200, 400, 600, 800, 1000, etc, would work pretty well. You can find higher grit papers at Auto-Repair shops (I've seen as high as 5000 grit).

I'd also recommend purchasing or making a strop if you don't already have one. A strop makes the sharpening/maintenance process a lot easier.

Good luck.

 

Welcome to the Forums, Btw.

 

I disagree, the angle grinder in the right hands with flap/sanding wheels is the ultimate poor mans workhorse.

Being a poor man I've had to use mine for years and years as I could not afford belt sanders and the finer knife making tools and I can polish your nails with my Bosch!

The only issue you'll run in to when sharpening tools with an angle grinder is the convex edge producing nature it can have and too much pressure causing over heating in the steel. Go light and even. I use mine professionally at a local place to sharpen all the tools they sell (I volunteer my spare time) and have done so with my own personal tools for years. I even create and modify bevels on thicker steel tools.

I don't mess with pocket knives or anything too thin though, not because it's undoable, but because I haven't needed to in a long time as I have enough files, stones etc to do that.













Angle grinder being the only power tool and finished 90% with it until final finishing with fine sand paper after.

All down to the right disk, practice and going steady. Always dip the steel in cold water as regularly as possible and always have one hand ungloved so you can test the steel temperature on full restoration jobs.

I am surprised that no one has mentioned a 12" bastard file. Cheap and great for machetes. In fact, I was sharpening a shovel with a file last night. And you can get things wicked sharp with a file, if you can remove the burr.

 

Here's a video from our own member HeavyHanded. He's using his invention, the Washboard Sharpening Block, but his technique is applicable to sharpening with a file also. Or holding a stone in your hand.

This is basically what I did when ifirst got my machete, then finished it off on stones.

 

A bastard file would work for bevel setting. Depending on how sharp you need it you could probably just leave it there.

 

Salon nail files maybe a low cost option.Not too sure on grits but I have read that some people do use them for touch-ups on swords. Grits range from a few hundred to a couple of thousand.

 

Use binder clips to clip a sheet of sandpaper to a flat surface about the size of a sharpening stone. A 2"x10" piece of 1/4 inch steel plate works well. Mild steel works fine for this, just make sure you fill in any pits with Bondo or similar. You'll want to figure out a way to attach the plate to a base from the underside. You could weld a bracket to the underside. Or you could drill holes and screw it to the edge of a 2x12, then fill the (countersunk, of course) screw holes with Bondo.

For a machete, you only really need 200 and 400 grit sandpaper unless your cutting tasks are super specialized and require a finer edge than 400.

If you want to do a convex edge, a mousepad glued to a pine 4x4 works well to go under the 200 and 400 grit sandpaper instead.

The first method is excellent for sharpening Scandi knives like Moras also.

 

2nd this one !!
A very functional tool that you can use for all kind of sharpening from sandpaper to paper with compounds etc. Definitely something you should look into getting and HeavyHanded will come out with an improved version in July!
