It's important to not get in a hurry. Americans are impatient and want to remove wood quickly, but this will only lead to bad things. Even if you are built up enough physically that your can actually stand to swing a heavy broad axe with some force all day long, it is still not a good idea. A swung axe of this style can be very dangerous, bouncing and deflecting and surging through the wood into the ground or worse into your foot. But if you take your time and let the axe do all of the work, it is very very easy to control and actually there is very little risk even though your are bringing a heavy axe head that is 8 inches wide down from a height of perhaps 10 feet or more. The only risk here is if the user becomes suddenly very stupid.
