I understand it was about as effective as sharpening scissors by cutting sandpaper!

thats what i was thinking was just wondering what they looked like. the chain looks good. wonder how it cuts, and how it would work on a regular saw

Probably not very well compared to a full chisel chain.

Do a search on Barracuda and Power-Sharp.

Wasn't that a feature on some Craftsman's? Never used it, but I've heard it's just a troublesome gimmick. Or is that what you're talking about, Barracuda and Power-Sharp, galde?

I have a small home owner craftsman around here that has it built into the clutch cover. It has a stone that you adjust the screw on while the saw is running to grind down the top of the cutters to sharpen.

McCulloch's PM320as featured this device but in my opion it was a waste of time and money, just another gimmick for the home marketers.

Hi, rivahrat.

I ran across some threads re self sharpening saw systems when I used to dig around in the old posts. Try some searches; I think that you'll find some photos as well.

Couple of problems with the self sharpening systems. First they use relatively expensive special chain which these days are not carried by many dealers. Second, the system only sharpens the top of the cutter which means the cutter sides dull and don't help in clearing material. Also if you don't add in an occasional hand filing of the depth rakers you don't get any bite. In my mind having to finish the job by filing the rakers to get it to cut is not very productive.

this is true. i just want to see what the system looks like on the saw. im good at re inventing stuff and just want something useless to tinker with.
