No I haven’t I shall google it I suppose this is where American English & English English differ a bit since shears to me is a much more of general word hence pruning shear – hair shears etc and necessitates two words rather than one I think most people in England if they prune use the word secateurs rather than shears although the noun looks as if it has French roots I struggled to find the spelling for them I admit not been the best speller although mention of that in the OED1
I bet branches move away from you armed with those although on a more serious note I expect from a tewchnical point of you there is less trauma caused to whatever you prune with those .
