If you're cutting muddy 'orrible sh*t it will blunt it really quickly. You'll probably spend nearly as much time sharpening as cutting, but it's well worth it as there's no point standing there getting the chain hot and not cutting owt.

Chains last ages, worth an occasional trip to a shop with a jig to put the proper angles back on as you can never quite get them by hand.

I refuse to lend chainsaws out to my mates as guaranteed they'll either blunt it or cut their arm off or something, and bone chips are so troublesome to remove from the clutch...
