get the chain saw out and get er done.....
a saw with an engine? in bushcraft? work of the devil!!
as much as i love chainsaws sometimes i would far rather go for an axe and bow saw. with these there is just so much to go wrong and so much less hassel.
at work when we work in the woods we take a truck full of tools, fuel and at leest two saws (even with a brand new saw you cannot be sure that nothing will go wrong with it). OR you can take just an axe and bow saw which you can happily carry for days.
say you havn't got a 4x4 imagine carrying the weight of the saw (6kg or more for the average chainsaw), fuel/oil cans (at leest 4kg), a toolkit and many other bits and bobs. after a 10 minute walk into the woods you are spent and then you may have troubles with your saw, won't start, blunting your chain on some dirt or stone etc. after all this i tend to get pretty angry lol.
with an axe all you need is a sharpening stone, a file and leather strop if you like. sharpening a bowsaw in the bush isn't easy because of having no vice to hold it steady but it can be done and all you need is a triangular file for touch ups, a spair blade or for short trips don't worry about a blunt saw as you have the axe as a back up!
also the relitive silence of an axe and saw is bliss compaired with using a chainsaw.
