That's great, Robert!
B.G. - I'm [sincerely] confused on how a bigger hole in the handle would better allow the trowel to be used as a stake. If it's a matter of line attachment and angling back the trowel doesn't work, wouldn't a small loop of appropriate lightweight cordage suffice as an attachment point?
As it is, it could be used as a dead-man, I think.
Of course, a bigger hole in the handle would make it a pinch lighter!
