    • Great professional blade sharpener
I own a small property maintenance business. I upgraded from a handheld angle grinder to this machine. It sharpens great. Very powerful and the grinding disc seems to be holding up great half a season in. It's ideally made for straight high lift blades. I mainly use Oregon mulching blades. The curve of the blade takes a little more effort to get a sharp edge but way sharper and even than an angle grinder. Makes changing out blades super easy and it seems like it will extend my blade life as it is easier to get a sharper edge without taking too much material off. ... show more

I looked at many different options of Blade Sharpeners. This one wasn’t the cheapest or most expensive. However it has to be the easiest to use. I used to use a bench grinder and could never achieve the edge or sharpness I wanted. My local Power Equipment store charges $6 to $9 a blade to sharpen. After using this, in no time at all, I had the right angle and super sharpness I desired on 20 of my blades. The grinder will pay for itself in no time. Anybody could use this and achieve results like a pro. I purchased the grit collector separately. Get the collector to avoid the mess. The grinder arrived quickly and I could not be happier with the results. ... show more

    • BEST INVESTMENT I have ever made for my lawn care business! Well worth the cost!
I immediately tried this and it sharpened with ease and the perfect angle. I had been using a hand held blade sharpener and could never get the right angle. Years of doing this, I just needed something better were everyone could do this no problem! All my blades are at a perfect 30 degree angle and mowing has been so much better, cutting the grass with ease a no chopping! If you get this, make sure you get the dust collector. It costs extra but well worth the price!!! It makes cleanup so much better. Definitely recommend this to everyone who needs to sharpen alot of blades!!! A learning curve on curved blades but can be done! ... show more

    • It’s worth the money
I’ve ran a landscaping company for ten years. I’ve sharpened blades with bench and angle grinders. I considered myself good. This machine showed me how bad I was. Everyone is. It makes sharpening blades to a perfect angle almost brainless. Anyone can use this with little training. Getting used to bringing the blade through takes no time at all. I’d recommend watching their video on how they say to draw blade by grinding wheel. I sharpen blades every single week. It has cut my time down by half. Would buy again. ... show more
