do you mean its gone dull, or you just bought it and its dull?

Machetes never come sharp, mostly dont even come with an edge bevel.

its the intent that the buyer will file it to what they need.. wafer thin for grass, thick for woods and bamboos..

like any knife.. yes, it should be sharp, but because they are thin and light they will cut ok when they are dulled, but they still need a bevel

most indigenous peoples will just use the bastard file, and thats it. you can actually get it very sharp just with a file.. so stop at any grit really.. but if you are doing wood chopping polish it.. grasses, toothy

cKc,
It was sitting and went dull. I sharpened it with 2nd cut file a few years ago.

I tend to run mine as large knives and micro-bevel with the norton fine india. Same with my fiskars billhook. I'm typically cutting shrubs and wood.

Tactical Knives Magazine Steven Dick has a wilderness survival school here in the Pacific Northwest, my neck of the woods, and he favored machetes. I always wanted to know what kind he used, and how he sharpened them. Here we have a lot of evergreens, ferns and blackberry's. I sharpened mine with the Smith's C #325 Yellow Diamond Oval sharpening rod, and then used the Super Stick Ceramic. I got the edge to shave, but it needs a slight draw to do so, not sure why. The edge is pretty thick.

the general reality of how you sharpen a machete is, you do what you need on the day for the work you are doing. its very common to carry the file with you, and regrind thick or thin, polish or toothy to what you need and what environment.

a toothy thin edge, almost like a burr will cut grass for a long time, but wont hold up on bamboo and wood. you just need to adjust for the environment.

best way really is to get out there and experiement on long grasses, light brush and wood and see the difference.

for grass you'd go for a very thin primary angle, wood you need to reduce the natural binding of the thin steel.


his channel circa 10 yrs ago is a good machete channel for modifications, use tweaks etc.

Yes, that is almost exactly what it looks like around here.

I sharpened this again, to see if I could improved the edge. I used my new Diafold Black XC #220/ Blue C # 325 and the Norton IC6 SiC/AlO (M Crystolon and F India), and then stropped. This edge is a lot better, it feels sharp, and will pushcut notebook paper. The issue is that the grind is so think, and it is a fairly severe convex at the edge bevel grind.

sounds like you need to buy a file, and grind it down to shape.. small stones on a machete are not going to get it where it needs to be easily

cKc,
I have a file, I had the same issue with the file that I have with the stones. The edge bevel is extremely asymmetrical, like 80/20 or 70/30, and also a serious convex. I need to just set it in the vise an file it down some to flatten it out, I have to go above 30° DPS to even hit the apex. It is 0.035"-0.040" BTE, and 0.055" a 1/16" up the blade from the edge. It really needs to be reground on a power machine, it is too much for my hands to deal with such a heavy blade.

a file should be able to cut that with less effort than you might put into sharpening a knife on a stone..

if tis not, then i suspect your file is dull. maybe a double cut file?

have you got a picture. im not sure which machet we are talking about. do ontario only make one?

I am going to get a new file on Monday, I think mine is dull.

I have this time stamped at 18 mins, take a look at the file cutting that axe :

Just think about trying to do with a stone what he does with that file.

another advantage to softer steels..

Jason either get a double cut file, or ensure you never go against the teeth of a single cut, which can dull the quickly

I can see light reflecting on both sides of the file, and it doesn't bite into steel like it used to.

Ok, I got a new file, a 12" Double Cut, 2nd Cut file. Cuts way faster than my other file, I can actually see it removing metal.

Jason,

Usually I use HCl or H2SO4 to reconditioning files, but is much safer to you, if you wanna try, use lemon juice. Put your file in a plastic recipient, use a toothpick under one extremity of the file and another in the other extremity for both faces been in contact with the citric acid and cover the file with lemon juice. After 24hrs the job is probably done.

Alternatively you could use warm vinegar.

As your file seems in relatively good condition I recommend you to test this with another file in worse condition and evaluate the result.

cabraljr,
Thank you for the tip. I will give it a try, I have seen it recommended before but I wasn't sure if it worked.

how does that work? is it etching the worn teeth to make them finer?

Yes. I think it etches off the deformation at the edge of the teeth, and leaves a cutting tooth. Not as good as a new file, but better than an old one.

Yes! Not quite the Jason file case that show no signs of rust, but acid cleans the rust and "sharp" the file. Rust has more volume than the amount of steel that originated it and tends to round the cutting surface of the file. I think that is how works.

I'm not the only one using a file card, right?

No, they are necessary to remove material clogged in the file. Must be used before the "cleaning" with acid. Some degreasing is necessary too.
Re: Sharpening an Ontario machete with DMT Diafolds

That reminds me, I need to pick up a proper card file. I have wire brushes, but I like using the right tool for the right job.


One thing I am having a huge problem with is my hands, both of them (the one holding the machete and the one holding the file) get weak and stark hurting when I am sharpening. I need to clamp these beasts to a table and go from there. I am still really not happy with the edges. They will cut, for sure, but they are not sharp how I like. Plus they are awfully convexed, and not in a good way. I am glad I got that new file, however, it is a beast. I might try some filed, super coarse edges to play with. I just like the idea of filed edges, ever since rec.knives a long time ago when they were talking about them. I sometimes wonder what happened to those guys, same on KnifeForums and BladeForums. About half a dozen to a dozen guys that did a lot of good work, I learned a lot. Unfortunately, I would only lurk, so I didn't get full benefit, and I would also take a time off knives for a while, then get back into them with a vengeance.

I talked to Mike Swaim awhile back, he learned enough to make intelligent choices, then got into other hobbies. Alvin Johnston passed away some years back as did a number of other guys, that was ~30 years ago and a lot of those guys were older at that time.

Cliff,
It is funny how you really don't know someone's age on the internet. I guess the default is to assume everyone is in your peer group. I was in my early 20's back then.

Ok, I finally got my 18" Ontario Machete sharp. I bought a new file, a combo file, 10" with an integral handle, coarse double cut on one side, finer single cut on the other. I was having several issues that were preventing me from getting a sharp edge on this machete. What I did to fix it was use a Sharpie marker to see where I was grinding. I was grinding way up on the shoulder, and the edge is very convexed, so I was getting tired before I hit the apex. I also uses a vise, which helped at first, and then I figured out a way to hold the machete and not get fatigued using it. The machete now slices phone book paper, and that is the very coarse file finish.

I got the BDUA10 File:
