[quote=grumpy]I started off using a chainsaw file, but found it way too slow, and it didn't help for "jointing", the process of lowering the depth-of-cut bars in between the teeth. The teeth slope downward, so as you sharpen them back you have to joint the chain regularly or you end up with less and less depth of cut. ................................
I'm with you on this one Grumpy,
I do use a file and guide but find it doesn't quite "cut" it.

The timber on the property I cut for firewood is mostly redgum and after a while even with regular dressing a chain change is needed.
I see you use the 12v hand held sharpener...hmmm interesting, may be the answer. Would this eliminate any need at all for a bench top sharpener?
Wonder how the cordless one would preform? Could budget for one of these.
Any feedback would be appreciated.
I too would like to see a video of one of these in action as suggested by Deejay as I learn a lot better from visuals (and hands on).
Cheers,
LS
