Fell an oak and was sectioning it up when I cut into a steel wire inside the round. The prior property owners had a hammock or something. Dulled out and chipped my brand new chain. Grabbed one of these bits and put it in my Dremel cleaned up and resharpened the chain quick and easier then with a file. Plus, when back to the oak the cuts was nice and straight all the way through. Read more

UPDATE! Yea these are junk, not worth the $. After just 2 uses on a 24" chain the stone begins to make an hourglass like shape which then gives your top plate a curve. I didn't notice it until I used a hand file on it again. A good brand hand file is just the best to get a sharper than new edge. * I bought these in three different sizes but this is probably the most used size. I own a small tree trimming & firewood business and have different pitched chains. I would say this is just as good as a hand file but a lot faster. The stone will wear down in diameter fast so I use them more for quick field touch-ups. Once you get in contact with the Gullet & Top Plate (at the right angle) just move it back and forth along the whole stone for only a few seconds with light pressure (Assuming your tooth isn't all beat up). I sharpen my chains after every 2 trees bucked. Not every tooth is going to be the same height or have the same damage to correct. Your Raker will determine how it will cut, not the tooth in front of it. You're welcome. 😎 Read more
