I have been pruning a tree before and really wished I had spurs when at certain places on the trunk or a sweeping upthrust limb..they would be useful there.
I suspect that as they are worked with they will become more useful as ideas on ways to use them develop.
That reminds me of a trick I often forget. Use of a loop runner for a foot stirrup on a spar.
