SporGain [Updated Lawn Mower Blade Sharpener 15°-45° Adjustable Frame

Assembly was quick and easy. Mounting hardware, including jig hardware, of high quality. Took the guesswork and stability issue out of sharpening thus complete sharpening was a mere ten-seconds per side. Worked well with my mulching blades too. Easily adjustable, and seems to be stable enough to offer a long useful life. For my use 30-degree sharpening was perfect and really made a difference in my first use of the sharpened blades. Perfect addition to the DIY garage.

WOW!!! THIS THING IS GREAT!!!-----------Blades are super sharp, balanced and cutting grass "Like who'd a thought it" Great pricing too!!! THANKS!!!

This works great to get a nice sharp edge on my mower blades.First, I have two sets of blades (6 total blades). I keep them at different angles for the different style of blade (high lift vs gator/mulch). This jig allows an incredibly easy adjustment of angle so for this it’s awesome.Adjustments are super easy all around. I feel safe during use, no worries that the blade is going to come loose or misalignments that I’ll ruin a blade.My one complaint is that the joint in the arm for the grinder, is a teeny bit loose allowing for a little play. I manually remedy this by applying slight pressure in one direction, to maintain consistency in each pass with the grinder. This is minor but it IS the reason I can’t give this five stars. Overall, I would absolutely purchase this again, given the price of other “name brand” jigs. This still allows me to get a fresh, consistent edge on my blades.

This sharpening guide made it much easier to maintain a consistent angle while sharpening my mower blades. It's well built, adjusts easily, and works smoothly with an angle grinder. The ball-bearing handle makes it easy to control, and my blades came out sharp and even. Great tool for anyone who maintains their own lawn equipment.

I was pleasantly surprised how well this jig works. Have to be honest, I had my doubts. I had to update my grinder since the handle came out of the frame a slight angle but the new grinder works perfect on this. I sharpened 6 blades which did not take very long and they now have the perfect angle they should, very sharp too. They look like they were professionally sharpened. I was amazed how bad my angle was using a bench grinder all these years, guess that's why they dulled so quickly! Just need to pay attention to your forward movements so you don't veer off to either side, keeping your angle true. Very please with this product and would recommend.

I have been sharpening my blades with a bench top grinder for years. Then I switched to my handheld grinder with a sanding paddle.This has now upped my lawn care game. Being able to sharpen the blades at a consistent angle is extremely helpful. The tool arrived and there was minimal assembly. As you can see in the video and pics, I mounted mine to a scrap piece of lumber and then placed that in a vice so I could do this outside. I just don’t have a good space or a workbench indoors to mount this (yet). I purchased the brass fittings at the same time in case there was unnecessary wobbling, but I must be lucky because I didn’t experience any play. The mounting bolt fit my Dewalt grinder fine and it slid into the sleeve on the tool with no play. There are pictured instructions included, but if you’re reading this and have any skills it all, you won’t have any problems. My blades fit snug and I attached the grinder. The blades I sharpened were in real rough shape. I’ve hit tree roots and there were chips in the blade. I set the tool at 30 degrees and began sharpening. I had to spend a couple minutes on each side of each blade…but I got them all nice and sharp, ready to shear some turf. If you’re considering this tool you already know how important sharp blades are. Because this keeps the grinder at a consistent angle it’s a no brainer. There are tools that are several hundred dollars you could purchase that sharpen blades but I feel you save money with this and likely do just as good. If you do get a model that has that wobbly play others mention, just spend the extra money to get the fittings and Loctite. You’ll still be way ahead on savings. Additionally I like how this tool doesn’t take up a lot of space with its small footprint. Because mine is on scrap lumber I can store it away and then get it out when needed.

Love this blade holder. Makes sharpening mower blades so much easier and faster. Allows me to sharpen the blades with a uniform and sharp edge. I would recommend this product to others. Well built and easy to use.

Well pleased with purchase. I have used it to sharpen six mower blades and was not disappointed. Some reviewers noted the angle adjustment is off. If you want a thirty degree grind angle you may need to set the angle different from thirty degrees due to relief twist in the blade. My blades have a fifteen degree twist so I have to set the angle to forty five degrees to get a thirty degree grind. The sharpener could be a little less loose; however, for the price it is acceptable and does a great job.

Très pratique, fais le taf.

Great device but came with with a loose swivel arm and faulty bearing which I believe was the cause. I will be seeing if I'm able replace the bearing myself with a better quality one at my local bearing store.Seems the bearing was crushed because they use a small split washer that sits up against the guts.Would be better using a normal washer that fits against the whole outside of the bearing so it doesn't get crushed.

This is a lot better than my other one. It is lighter and a better design. And the price is fantastic. Would highly recommend this to family and friends for sure.

I always sharpened mower blades myself as they can be reused for years... but the angle was never right: 30°. That pissed me off so many times. I had no idea how to train my hand to do a real 30° full-length blade angle... So I bought this "guide". IT'S AWESOME... It's not perfect; there is a bit of play in the angle grinder guide, but it's minimal... Blade still gets out really great.

Sturdy construction, high quality parts. Delivery was fast.
