Yeah Dave, as you imply, they can turn and bounce and get stuck etc. and the worse is a skid off as it happens so quickly - but we are talking to adults I assume? Most of it is commonsense and the scars teach the rest. We all started somewhere! And some of us still have all our fingers and toes. I think there are probably chain-saw intro courses about, unlikely any axe-using courses. Anyone swings a few pounds of sharp metal about on a stick needs commonsense else should go back to watching TV. or Youtube.
A carpenters' axe or small hatchet will do the same job of under cutting, just take longer. Sharp tools do the work, not our muscles.
A wooden wedge or three knocked in with a club hammer rather than heavy wedges and maul or sledge will gradually open up the same splits. I have felled big trees with just axe then ripped six yard by three foot thick trees into quarters with wedges alone and then split planks from them ... a small stump will be easy if you take time, it's impatience does us in. rocks are similar, most will fail if you find a fault or tap along a line. Lots of our ancestors learned that stuff the hard way, shame to relearn it!
And much as dislike Argyll's ideas usually he is right about digging, I hate it myself but it is just time and perseverance with a mattock or pick and a spade. Bloody roots always p*ss me off though, always one more needs chopping before it will heave or winch out.
