Hi Rob. Hope you don't mind me posting to you directly. I noticed your thread from a couple of years ago about Maya chains. I bought one a while back because it was ridiculously cheap (about four quid for a 3/8 72DL, straight from sunny China) and I thought it would do as a disposable for some rough stuff. Several decent sized ash trees, lots of poplar and a load of scrub later, it was still cutting well and I was impressed enough to try and track down a few more (which is what led me to your thread). Before I could do anything about that, I hit some dirt in a stump and blunted it... Which is where the problem starts – I can't sharpen the bloody thing! It appears to have hardened tips added to the teeth. These seem to be more brittle than normal teeth, so some have chipped where it's hit stones etc, and my sharpener (generic disc-type bench-mounted) won't touch it! Is this something you've come across? Any advice?

Cheers, Kev.
