this little fella is great, a little pricey compaired to hand filing but makes up for it with the time it saves, this mount on bar chain sharpener files almost any chain you can throw at it, except for ripping chains because it cant go any smaller of an angle than 20 degrees, we have been doing a lot of huge jobs lately with nasty metal in it and thank god we had this on hand, with the time its saved us i swear we would still be on those jobs. my complaint about it, on the 404 chains weve noticed that we only get a couple of good cuts til it craps out on us, the manufactorer says its not the angle but the terrible stuff we are working in, probably all thost really fun nails buried in the wood, anyways, hope this helped

you can find em on baileys website and yes it hooks right up to a car battery, it outlast regular electric stone 100-1 easily and about the pic size, my mac doesnt come with any type of photoshop so i just find what i can on the internet that is a respectable size,
 
Been using one for a year now. Hand filing is the bomb for touch up between tanks of gas but the sharp boy is the only way to go after hitting metal, stones or digging in the dirt.

We'll sharp boy our 36" stump saw before we cut a big bole down. Quick set up but not as consistent side to side as proper bench grinding.

Still, we find our chains lasting longer and using fewer files.
 
yea i could see using it if you hit metal or a rock,but for regular touch ups it probably takes off to much meat,and has to be slower than hand filing.

Actually we find the opposite is quite true. It takes about 20 seconds to set it up on the bar and what we do is lower the wheel (power off) to the chain and slide a cutter up till it just makes contact. We then lock the stop pawl up against the back of the cutter and away we go.

I can do 32 inch bar, full comp chain in under 5 minutes and I know all cutters are at the same angle. This also allows us to grind cooler, less hardening of the cutter and making it easier to hand file later.

Even though hand filing is an option we always find one or two work hardened cutters that mess up the files so we just use the sharp boy as a matter of course.
 
yeah, I find it best to hand file them, just a little though. We used to use a filing gauge for that but have gone to free hand.

Every couple of weeks we put it on the bench grinder to make them all uniform.

If you go too much on the file you'll notice it right quick.
