Do you own a file and can you spare 5 to 10 minutes?

I've just used a file before a it works great. Put it in a shop vice. I'm pretty sure that tool has been heat treated so I wouldn't use a grinder.

I use a flap wheel on mine and it works perfect. I take down any high or low spots with a file first. I think a Dremel is a good idea too

A place that services lawn mowers, like a small engine shop, may be able to do it. Like sharpening a mower blade.

Is that a digging tool similar to the Lesche digger?

If so, I would use a good sharp file & only file the scoop side edges.

I take my diggers to a knife sharpener. He is a Vet, that charges me $6.00 per tool to sharpen. I can cut paper with my Lesche, Sidekick, and Diamond Digger! :occasion14:

Got a Harbor Freight close by? $10 or $12 will get you a nice selection of diamond sharpeners so you can sharpen most anything you own. Not to mention that investment will last you years, And you can carry the stick sharpeners with you in the field.

WARNING! Stay away from the pink ones you chuck up in a drill!!!!!! They have a bad habit of blowing up!!!!

I sharpen my diggers with the same gear I do my axes. 10" single-cut mill ******* file.

But in these politically correct times you can't say "*******" even though it is a recognized item available in file catalogs, as well as a condition of birth.

When I sharpen my shovel, I carefully use a belt sander. I would attach your shovel to a work bench with a vise or clamp(s) so it is stable to work on. Keep the sander moving or the metal heat up. It only needs a few passes with the sander.

No. The ones to use are the flat ones like a regular sharpening stone. The they have a little one looks like a pen. Has a groove for fish hooks etc. a flat side and a round side. Great to hang on a key chain. The one I really like is the block in a holder. Four grits, you just flip the block. The single ones you can just leave in your goodie bag to touch up rock dings in the field. If you loose it it's only a couple bucks to replace.They're usually over by the scissors & magnifiers type stuff. So for $10 or $15 bucks at the most you can sharpen everything you own. $21 if you get a chainsaw chain sharpener. :icon_thumleft:

A simple 12" flat pɹɐʇsɐq file will sharpen almost any digger. If digger has teeth use a triangular shape.

With what I was suggesting buying from HF, you should be able to sharpen 99% of the things you own for under $20.

Since were talking sharpening without dinging your pocket book. My grandfather showed me a cool system back in the 50s. Get yourself a piece of glass about 24" square. Wet a piece of sandpaper & the glass with honing oil. In those days it was the little can of lubricating oil from Pep Boys. Work your edge through the grits by just wetting & changing sandpaper. I've got some 3200 grit from a hobby shop that'll put a beyond razor edge on a knife that shines like a mirror. If you're really cheap, save your sand paper by placing waxed paper between the sheets. I've got a slab of granite counter top I use now. Went to a shop that does granite & asked if they had any drops. They let me pick what I wanted & even squared it up for me. My cost? Two Pepsis and a cigarette.

Hope this helps you get going without much work & cash.
