I bought one last weekend at Lowes.. Works ‘OK’ but not great.. I ended up taking the attachment (head thingie) off and just eye-balled it — much easier. I agree that using the head they provide (aluminum carbide?) whether it be on an angle grinder or whatever else is best since it wears faster than the harder abrasive stones.. Anyway, my Honda commercial blade is now sharp (hadn’t been sharpened ever and was very dull) but will likely need regular sharpening to ensure it does its job..

I have one of these. The 4.5in grinder works much better on my snapper ninja blades.

I had one of those $7.00 drill guides with the plastic guide and that was cr**, lasted about 5 mins. I had good luck with the Dremel with my beat up Yard Man blade, really saved time and did a fairly good job. Invested in a Toro at the end of the season last year (so my kids could mow the lawn - $600 mower so I can pay my kid to mow the lawn, something wrong there). Haven’t tried the Dremel yet, sounds like it won’t work, based on others experience. My coworker just bought a $300 mower blade sharpener, so maybe I’ll give him a couple bucks and have him do it a couple times this year.

It not worth it. You can use your dremel without this attachment to sharpen your blade. I have one and like most of your reader said, it won’t sharpen around curves, it sticks and if the blade is thick forget it.

Angle grinder and an 80 grit flap wheel. 5 minutes to make a thrashed blade good as new. I sharpen my blades once a year, and they get really beat up.

Guess I’ll be the skunk at the church social. I bought one of these two years ago and it works fine for me. My property is very sandy so I sharpen of three blades every week. I’m still using the original stone that came with the guide. My mulching blades have two curves on each side and the guide goes around them ok with a little patience. I’ve also used files, bench and angle grinders to sharpen blades and I find this works better and/or faster than the others.

Bought one of these and wish I hadn’t - it’s worthless. Put a big grove in the stone in about 20 seconds because the guide was no where near the original angle of my mower blade. Instead I ended up using the sanding barrels and found they work very well for sharpening. Just do it freehand and it will be fine.

I just sharpened my Lawnmower blades yesterday. Used an angle grinder.

Angle grinders, bench grinders and handheld or bench mount belt sanders all work a 1000x better than this.

Don’t get me wrong, I love all three of my Dremel tools - but they are for small and precise work NOT large, rough work.

I wish this was a hot or not, because I’d give it a big……

NOT!

Chipped by stones? Where the heck are you mowing your grass?

I can’t think of a slower, more pointless way of sharpening a mower blade than using a Dremel. The blades are not made of hardened steel and after a few cuttings are well worn, if not chipped all to hell by stones, and the only way you’re going to grind it down to a new edge in a reasonable amount of time is with either a benchtop or angle grinder.

I got this with a bit kit. On my version there is only the lower angled support. I’d imagine that the other support only makes this thing worse.

Mine came with an attachment kit. The guide is not wide enough for my mower blade and sticks when you get to the curved parts. I just use my angle grinder and I’m done in seconds.

Agree with Pepster — using a dremel for sharpening is just fine, but the attachment is worthless. My Toro blade has a twist to it that prevents the attachment from working along the entire length. I just eyeball it.

An angle grinder works too.

I agree with Jim German in theory. If you take off the blade and sharpen it every month or so a file is fast and easy, but if you let it go all year without touching up the blade with a file, it’s too much work.

I usually subscribe to touching up the blade every month, but I just sharpened my mower blade after not sharpening it for a season and it would have taken too long to get an edge — in the best spots it was a flat section 1/16″ wide.

Angle grinder, end of discussion.

Geez, I like power tools as much as the next guy, but a couple minutes with a file is really all thats needed to sharpen a lawnmower blade, its not like you’re doing brain surgery with it.

If you don’t have a dremel…

Another option: I bought a cheap 4.5″ angle grinder from harbor freight: Item number 95578, the blue one for $10 on sale and a grinding wheel for $2. Once the blade is secured in a vise, I used the grinder to take the big nicks out of the blade’s edge. Just a light touch is needed, otherwise you can remove too metal if you get carried away! I use a bastard mill file to fine tune the edge. I also hear its good to check balance of the blade after its ground (on a nail in a garage wall should work).

Not worth it. Grab the basic grinding tool (pictured with the guide) and just eyeball it. Most blades won’t fit into the narrow gap in the guide.

I’ve tried using mine twice and had to pitch it both times because the blade would not fit.
