Stopped by one of my loggers today. Saw his saw box was open. I was eyeing what looked like a 6month old or so husky 576. Felt awfully bulky and heavy compared to the 372. Oh and they had already busted the chain brake handle off of it !!! Saw the boxes of new chains and then in the top tray he had all the "junk" used chains. That still looked like 80% plus off the tooth was there. I said you gonna sharpen those? He said noah once they pull them off they won't use them again. He said grab a few. There all 20" loops 3/8 so I got 4. Looks like I got a semi skip one or something??? A factory low vibe or kickback chisel chain that may of come on a saw. And then 2 loops of full chisel oregon /husky chain. Did pretty good !!
