Charlie I can't believe you admitted that on a public forum....
Seriously though, the Granberg is to sharpening chainsaw chain as the Apex Edge-Pro is to knife sharpening. If your a little off on your angles free-hand, the tool is your friend for staying on.
I've seen people though who swear up and down they can sharpen a loop of chain, but when you watch them cut it says much different. Case in point; my nephew makes his living as a wildland firefighter and even teaches saw safety stuff for them. When I watch him saw with a chain he sharpened, I feel sorry for a powerhead.
Post a picture for folks if you could.
They were made by different folks and sold by different folks over the years. Sears and Montgomery Wards at least.
The earlier ‘file n joint’ by Granberg were some of the best I’ve been told.
A picture would help folks recognize them at yard sales and such.
257,
Since the photobucket debacle awhile back, I haven't taken the time to find a new photo hosting site. The Granberg in picture posted by Roundoak a page or two back looks pretty much just like mine from what I can tell.
Funny you should mention finding them at yards sales. My kid often goes to yard sales and awhile back, he bought a box of well-used-tools and some sort of chain sharpener thingamajig was in there.
257, I enjoy your posts on chainsaw topics. Thanks for sharing it.
