Designed Specifically For Mower Blades ░░░ Full Demo In My Video
As someone who has been sharpening mower blades for over 20 years (I used to have a landscaping company called "The Sod Squad"), I swear by this mower blade sharpener. This is because of two reasons: the handle design is very easy to use (no risk of cutting yourself), and the actual design of the sharpener (one carbide side and one guide) is specific to mower blades. The sharpener works very well. Mower blades are not knives, so you don't need to put a bevel on both sides of the blade. You also don't need to get them razor sharp. Instead, a mower blade just has a single bevel, and this is why this sharpener is ideal. It's true that you CAN sharpen your mower blade with a file. But it's way easier and faster to just swipe the blade with this sharpener. ░░░ A FEW NOTES AFTER YEARS OF WORKING ON MOWERS ░░░ 1. If your blade is really old and beat up, you may need to take some of the dings out of it with a file. That will be determined by how many rocks and sprinkler heads that you've hit. 2. While it's tempting to try to sharpen the blade while it's still on the mower, don't. It's way, way easier to take the blade off and sharpen it. Plus, you'll do a better job. 3. If you don't have a bench vise to clamp your blade into when sharpening, just use a couple of 2x4s screwed together to hold the blade in place. 4. If you really want a well-running mower, use a blade balancer like this one: Oregon Lawn Mower Blade Balancer 42-100 . Balancing the blade is not essential for homeowners and few people do this, but it's ideal if you're mowing a lot commercially or just really into having a fine-tuned mower. 5. A razor sharp mower blade is really overkill, because you're just cutting grass. So my advice would be to not obsess about getting a perfectly sharp blade. This sharpener will get it plenty sharp. 6. Regular sharpening, like every season or even twice a season, will keep the blade nice and sharp. If you let it get too dull it'll be hard to sharpen (like after several years). So it's a nice design with the built-in brush and sharpener angle. I strongly recommend it. ................. This product was NOT given to me as part of any promotion. I bought it after doing some comparison shopping and this review is entirely the result of my own opinions and use of the product.

This works, worth buying...
Good field sharpener for your tools...axe or machette. I have used it on a cheapo Harbour Freight hatchet, a Fiskars axe and a bushcraft machette....got a good edge on all the above. It seems durable, keeps your hands safe and is reasonable to carry in your tool box, etc..

Good Blade Sharpener
This is a good product for people who don't have an assortment of tools or a garage to complete routine work. The sharpener works well with little effort and provides an even finish on the blade.

Simple - Easy - Results
I was tempted to buy one of those sharpening stones that uses a drill. But then I saw a YouTube video reviewing this hand-held sharpener and that changed my mind. I ordered this along with a new mower blade thru Amazon. The new blade was painted (?) even on the cutting edges. I used this to remove the paint and put a sharp edge on the new blade in less than 5 minutes. It was very easy to see the sharpening action as it removed the paint from the blade edges. The wire brush is helpful but not super-durable, as I ordered the sharpener first to try and revive my old blade, but after wire-brushing it discovered cracks that made the blade unsafe to continue using. The bristles on the brush got bent pretty easily. Still handy to have it. Especially for the price and ease of use, I'd recommend this all day vs. those drill-mounted grinding stones.

However I recommend two of these products purchased at once
Ok so this did the job on my Oregon blades. Made them very sharp and the lawn cut extremely well. However I recommend two of these products purchased at once. You see the angle of the blade was different then the set angle of the sharpener. Even though this product cut right through with little effort it dulled considerably before the last edge of the second blade and my second blade could not get as sharp as the first. Much of the carbide was wasted grinding the bevel angle. So if I had two the first would change the bevel angle of the blade and the second would blow through and fine tune the edge. From here out though I should have no issues as the grind of my blades are now set. ( I may have to grind chips out once in a while with the wheel) I did order a second set direct from Smiths as it’s considerably cheaper. But these did sharpen very well I am impressed. Minus one star because the sharpener couldn’t make it through one session. Minus one star because I couldn’t just order the replacement carbide piece.

Really bites into dull blades.
Bought a cheap camp axe and ran this down it a few times and now it takes chunks out of trees. It is easy to use and very safe. The size is perfect to pack along. It feels really well built. I can't believe the difference it made on that dull axe. You can feel it grab the first couple of passes then smooth out. That's when I knew it was sharp. The value you are getting with this is wonderful!

Great Manual Lawnmower Blade Shatpener
For a hand held manual sharpener, this thing works great. It sharpens the blade at the correct angle with ease. Yah, you may have to run it along the blade 15-20 times every blade or so but looks like a professional sharpen and very little balancing issues if done evenly. Great tool for sharpening lawn mower blades. Will get another when mine shows signs of not working well. Going on year 2 and it's still doing great!

Great, but didn't work on my mini axes.
I bought this set to sharpen some new throwing axes that were completely undamaged and just not sharp enough to stick to the wood target. Out of the 4 diffrent brands, (which were the Woox Volante One-Handed logo Axe, WATL premium competition thrower, the Wicing 3 pack throwing axes, and a Big 5 mini hatchet by Buckshot) this little yellow pull sharpener only sharpened the WATL axe, and with more time and strength, the Woox axe to where it would stick. Maybe, this pull sharpener is NOT ment for very thin, full tang, mini throwing axes that are 14 Inches and under. As the WATL and the Woox axe have wood handles and are allot bigger and thicker than the other throwing axes.. But anyway, this did the job easily on the WATL/Woox axe when I pulled firmly with the honing oil that Amazon recommended. Instructions were really clear and it was fast and easy. I used the lansky puck on my smaller axes and it worked really well. The fact that I bought all 3 of these things for under 25 was worth it. I know others have stated that the tool won't work on heavily damaged axes, so I expected it to do the job with blades that just didn't come sharp. But Ya, it only sharpened 2 of the bigger ones and a machete. I'm new to all this stuff, so maybe I'm doing something wrong with the smaller axes and just need to adjust, but idk. The WATL blade was my favorite out of the large throwing axes, so I'm glad it atleast sharpened that. But so far, it's worth a try for the price.
