OK
I was one handing a darned Shindaiwa top handled and cleaning a palm.
Had my left hand on the seed pod and cutting the bottom of it with the right hand.
The saw caught some of that potatoe sack type fibres and raced upward straight through my thumb.
Was bad but soldiered on with big bandages. Still got a thumb.
So what I learned was never line up with the bar/chain, cut so that if saw goes up or down it's a miss.
I'm not saying do it, and I know the real world, just dont line up with that cutting edge. Palms honestly test you out.
