SporGain [Updated] Lawn Mower Blade Sharpener 15°-45° Adjustable Frame with Ball Bearing Manufacture Handle for Right & Left Hand Blades, Use with Angle Grinder, Black

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.

Sturdy construction, high quality parts. Delivery was fast.

Très pratique, fais le taf.

I knew there needed to be a better way than freehand with an angle grinder then found the solution on Amazon. Great bit of kit- Well done.

I get that this is one of the many American Sharpener knock-offs and after watching numerous youtube videos of people's horror stories I was nervous. I'm happy to report that this one didn't have any of those issues. This thing is awesome! Everything went together easily, it works phenomenally well and it didn't break the bank! Believe me, I really want to support American manufacturing but it's difficult to rationalize spending $220 vs. $50 when both items are equal in quality and functionality. If the American version was $75 I would have bought it. Sorry, but like everyone else, I'm not made of money.
