thanks for posting that, never seen them. always just used a file or one with the gauge on top. i like that it also files the raker to the correct height - great!

I have to say that is a pretty inaccurate way to sharpen a chain saw. Your not having all teeth the same lenght, angle, and depth, so some teeth are doing all the work and others not much. It maybe fine for pine but not hard woods. There are 4 angles to properly sharpen a chain saw pretty hard to do freehand. Field touch up is okay, but I would carry 3 spare chains with me, easier to swap out with a fresh chain than sharpening it by hand. I used to cut about 15 cords of fire wood a year, and not having a properly sharpen chain is very fatiguing to use.

While sharpening a chainsaw chain, always secure the perfect chainsaw sharpening angles in the cutter as it's necessary for excellent cutting performance.

There are two ways to sharpen a chain, by "eye" and with a sharpening guide or device.
I have been doin' it by "eye" for over 40 years, so I'm pretty good at it by now. However, the Stihl guide I recently purchased will insure that all the heights and angles are the same. Mine done by eye are "real" close, and for chain saw work that's close enough. You can telll when a chain has gone wonky and needs a sharpening. You can tell even quicker if you see a spark when sawing. That's doesn't always means all the teeth are dull, just a few. It may still work and you can keep going if it's still cutting fairly well. There are times when stopping to sharpen just isn't in the cards. Yard trees are THE most likely to have a long forgotten nail or hook embedded in them, so you have to be more careful with those.

I remembered this great video which tested all the popular chain saw sharpeners:

I agree. I’ve tried a few different ways and can sharpen by hand. This is the go to for me.

BTW Pferd is the company that actually makes these for Stihl. They’ll be in blue instead of the pretty orange though.

can you replace the files on these? i see that they come with files already, just wondering if i can change the file size for different saws/chains. does any one know? thanks

You can replace the files but I don't think you can use it on different size chains. When I bought I had to know the chain size to order so I am assuming it is more than just file dia. But has to do with the heights of the files also.
