This came out of a Husquavarna Chainsaw case and I have no idea what it is, there were a few of them in the case. Anybody got any ideas? There are no markings or numbers whatsoever on it and its a flexible white plastic.
Strong theory DaPro, though, one might think the whole edge might have 'teeth' and/or be 'sharpened'? I've no real idea, and Pro is usually spot on, but it looks as though it could be a cleaning/chain removal tool, though most huskies don't need a tool for chain removal... Are the edges as sharp as they look? Maybe it's a way to clean debris from the chain/teeth? Not sure, and a quick google for weed-eater blades, as well as plastic chainsaw tools didn't help. Did you buy it new? I'm wondering how some weed-eater blades got into a chainsaw case. Maybe a picture w/dimensions, or something to compare it's scale to might help. The teeth seems similarly shaped to the 'cog', the front 'wheel'(cog) that the chain turns around at the tip of the saw. Maybe it's for cleaning/clearing that? Let us know if you find out. Have you checked the manual? There's usually a list of 'parts.' Maybe that'll shed some light on the subject?
I found some on ebay after Pro mentioned it, it's exactly the same,http://cgi.ebay.com/48-x-Weed-eater-Poly-Plastic-Replacement-blades-cutting-/370510379326 That's what I found
I have no doubt, but I was concerned that the chainsaw needed some parts before I started it or that some pieces commonly wore out.
I used them as well, should have tossed the money out the window.........terrible. Maybe the guy you bought it from found a use for them clearing debris out of his saw??
