SDMS Chainsaw Sharpener, Portable Chain Saw Blade Teeth Sharpener Work Sharp Fast-Sharpening Stone Grinder Tools Suitable for 14/16/18/20 Inch One/Two Holes Chain Saw Bar

Looks cheaply made but does a good job, sharpens in seconds, pretty amazing

This product did not work, the plastic was shredded by the chainsaw in seconds, the closure pin to keep housing closed wouldn't stay latched. Sharpener stone was off centered. I'm not waiting it doesn't work just that it did not work for the saw we have. But I'm not overly worried as it was rather cheap to begin with so I'm only really it $10ish dollar bucks, I wish I still had them but it read worth a shot to see if it helped or not.

It grinds on the top, or outside of the cutting blades. Makes a little difference, but ultimately wrecks the blades. I don't see how anyone can say it works. I got my money back, so I gave them 3 stars

This cool little sharpener is easy to use. It's especially good for the occasional chainsaw user who might not be so good at using a file-type sharpener. It's plastic so don't treat it roughly. Also it's not designed for bars without a hole.

This is a nice thick plastic case with a stiff, but easy to use, locking mechanism. The blade easily latches onto the case, and the grinding stone is easy to push down with the lever for the right tension. With how often I use my chainsaw, and the fact that it comes with spare grindstone, this sharpener is easily going to last years to come

Not sure about this product. It was supposed to be the lazy man's way to sharpen the chain. It kinda did but then it kinda didn't. The chain was dull again after just a couple of cuts or did it even work. Back to the old fashioned file.....

The grinding stone that was sent does not even fit the device. It would just be loose in there. Second after seeing how it might sharpen the blade I decided not to use. It would file down the blade stops that keep the teeth from biting too much at one time. Third it looks like it would file the top of the teeth and make the chain wear out very quickly.

I have one for my saw, love it ,works great , chain comes out sharp, I bought this for my dads chain saw. Once he figured out how use it, he likes it, he s 85 been sharpening saws a long time and he likes how nice this product works on his stihl chainsaw.

It broke the very first use. I did nothing wrong and tried to use as instructed. Broke immediately

Great product

It was a quick easy way to sharpen my chainsaw blade but it does only sharpen the one set of teeth but it worked for me it was a little hard to get used to and I did run it into the plastic the first couple times I tried using it so be careful but I would buy it again

The stabilizer pin is to large, won't work on all chainsaws

Une vrai arnaque. sa détruit ma chaine je le déconseille fortement
