The advancement from the axe to the chainsaw might just be the greatest evolutionary leap in the history of tools. Think about it. Seemingly overnight, the task of felling a tree went from time-consuming and incredibly laborious, to amazingly quick and effortless.

Com: Kelly : When you are so early he hasn't said boom. How?!?!

He at least does it 10 times a vid and usually the first 30 secs he says boom.

Com: WestCrook : I thought he was going to turn the chainsaw on then place a blade sharpener on the running blade..

Com: Slave : I usually file guide teeth 1/16 or so lower than cutting teeth and I've also sharpened same chain 7times or more before I scrap it...
