Review: Nice Jig for sharpening mower blades - Came fully assembled (who even does that anymore?) 4 different stems included to fit the Handle threads of most any 4-4.5" angle grinder. I mounted mine on a couple pcs of scrap wood, so I can use this while temporarily attached in a vise. Who wants to tie up bench real estate for a sharpening jig, that only gets used once every 2 or 3 months. Works fine, to keep a consistent angle grind, a little sloppy in the articulated joints, but acceptable. Works freely without any resistance... You can tighten the joint bolts, and lessen the (minor) side to side slop, but then it fights you with a little with resistance during use. I assumed 30 degrees would be the normal angle to set. but my blades were closer to 35. You can't really set it to "just any" degree angle. There are notches within the adjustments. Meaning you can't set it to 32 or 37 degrees (easily). Only just the notched 5 degree increments. just match what you already have on your blades, and keep a wet sponge nearby, to you can keep the blade from getting too HOT. Warm is ok, but getting the blade really hot will take the temper out of the metal, and then the blades wouldn't be as hardened, and lose their edge PDQ. Minimal (less) grinding is way better for you, the blades & your Flap disc too. (I use a 40 Grit) This thing is kind of pricey for what it is, and I wouldn't have bought it if I only had ONE mower, but I have many mowers, and most of them have many blades. A nice jig unit, and I won't miss the dropping off, and remembering to go pay & pick up the blades anymore. I keep my blades sharp, so I can mow faster, with out the re-runs for missed patches, and try not to intentionally run over too many blade edge wrecking objects. Pick up the rocks and sticks, or you will be running the same ones over again next week.
Review: Sharpens a huge variety of blades & works with many different grinders. Tighten angle set. - Not the easiest thing to use but reasonable install and setup. One caution: REALLY tighten the grinder angle set screw, hand tight won't do it. Had to use pliers on thumbscrew to keep it from lossening up and changing angle. Otherwise, works pretty good and should work with a variety of 4-1/2" and 7" grinders. Also recommended, check your grinding angle against a new blade. I thought my blades were 35° and I was having to grind ALOT to get them sharp. Turns out they we ground to 40°. Went much faster after that change. Always check blade balance after sharpening (wall mounted balancer recommended due to increased accuracy and sensitivity). Recommended.

### ⭐⭐⭐⭐ The fastest way to sharpen a mower blade but you have to play with the angle settings
*by A***D on April 22, 2025*

So I've been sharpening my mower blades for years using bench grinders and a nail for balance. I recently heard about these new flapper wheel grinding disc style sharpeners, so I thought maybe I should move into this century, with technology. First I will say it's easy to assembly, functions as it's intended to and with its different anchor shafts, should fit most grinders on the market. I know it fit my new Metabo, that I bought for this task. You don't need a special grinder, just one that hold the flapper / sandpaper grinding discs. I wouldn't use standard grinding discs, as they might shatter and/ or cut too fast. This is about making multiple passes and losing as little metal as possible. In fact it's a lot easier to balance afterwards, versus with the grinder. So why 4 stars? The angle indentation markers it comes with don't seem to make sense. I set them for what the manufacturer of my blades tells me they are and this things angle adjustment seems to be nearly suggestions. I end up setting it and then making a fast pass, to see if it needs to be adjusted. Once set, it fairly straight forward. The arm holds the grinder at that angle and all you do is lift and glide it onto the blade and push straight through and lift at the end- repeat. Like I said, super easy to get balanced. Id say it cut down my sharpening times by half, from using a bench grinder. But here is the second caveat, it doesn't seem to be sharp enough. I recently cut my grass with these newly sharpened high-lift blades and found too many single strands for my liking. Even with my blades nearing the end of last season, previously being sharpened by a bench grinder, they still left my grass flush with maybe one or two stragglers. This years first cut wasn't as good. Maybe I need to practice more and see if it's me, but you can only make so many passes and fear heating the blade and making it brittle. Not good for a yard with a lot of hidden rocks. I'd say if you catch this on sale, already have a grinder and sandpaper flapper disc, then give it a shot. It's a 100% better than those things you attach to your drill and hope it doesn't blow apart with you sitting under a close deck.
