Sharpening a trowel

adamdetector · Nov 3, 2017

So yesterday I received my new trowel which was made out of metal. It has two serrated sides. One on the left and one on the right. The trowel is very sturdy but the serrated edges are not sharpened at all. So I was wondering if anyone knows how to sharpen one. Thanks!

I used my angle grinder with the same grinding wheel I sharpen my mower blades with. Quick and easy.

get yourself a round file (one that fits into the grooves) and get at it

You can use either a grinder or a file for sharpening flats, but if using a grinder make sure you go slowly so not to over heat the steel. Doing it too quickly will cause the blade to become brittle.

If using a grinder, use a flap disk and make single quick passes along the blade pausing for a few seconds between each pass.

Used a grinder and file on my Garrett digger.... worked like a charm. Went through roots and grass like butter. If your digger is good steel it should an edge for quite a while.

Go for it............

Hockey arena or shop where they sharpen hockey skates. Takes 1 minute and a few bucks

Most diggers are fairly thick when you get them. I use a small belt sander to sharpen the edges.

By holding the blade you can tell when it starts to getting hot. You can wait a while or dip it in water to cool it before sharpening it some more. Once it is sharp I touch mine up every now and the with one of these.

I like to keep my digger and shovel sharp.

I use a belt grinder with 80 grit to sharpen my mini 18" takes about a minute to get it sharp enough for digging.

Chain saw files work well for this.

No, getting to hot causes it to become SOFT, you are effectively over tempering it. So that it will never hold a sharp edge for long.

Either way, point being it will ruin the edge.

Yup sure will, just wanted to correct the info so people understand why it ruins it.
