Or indeed, is the oracle himself knowledgeable in this area? 
We have a wood burning stove and a fireplace. We have a number of large logs gifted to us by friends when their trees come down in gales which we have been cutting using a saw and axe. It's hard work, and takes a long time to get through. It is DH's birthday soon and he's a difficult man to buy for. I was wondering about getting him a chainsaw, to deal with the wood but I have no idea what I'm looking for and I'm a bit scared of them
Can anyone give me some info on what I need for cutting firewood, rather than the terrifying weapons of mass destruction that my tree surgeon uses? Thank you!
