Yah, I NEVER throw away a chain, no matter how ground down. Or bars for that matter. I grow bamboo, and I put a dead bar and chain on my 025 to cut roots in the dirt. Saves hours of chiseling and cutting with a shovel.
The RM2 on my 'new' 361 is brand new. Still factory sharp. I may sell it with the bar, as I cannot see using a 28 inch bar on a 361 for anything. As much as I suffer from WCLBD, 25 is about as long as I want to go on the 361. Though I will have to try the new backup saw with the 28 before I sell it... and then maybe I will like it as much as I like the 25 inch bar when I bought that, and then I will need to try a 32 inch bar... and then of course I will need another backup to the backup 361 to sate my CAD, and then....
