Torch,
As far as I know, the Powersharp system is currently limited to small saws, usually about 40cc or under. I'd think you could probably put one on your Stihl 025 if the bar mount matches any of the Powersharp bars, but that might be about the upper limit of currently available Powersharp options. You would also probably need to make sure your 025 is using a 3/8 lp (picco) sprocket, as I don't think they are made for .325 chain. I've used them and they work pretty well, but I will advise you that if you push on the bar hard enough to flex it or push it against a curved surface when sharpening it, your saw will cut to one side (I inadvertently learned this when I pushed it against a crowned road when sharpening). Also, it seems to me you have to be extra careful of the chain, as it seems to more easily cut things with accidental contact than a regular chain.
It is VERY easy to sharpen the chain and it cuts very well. Just some different stuff to get used to.
