Hey Scott…  I’m curious about your experience with such pruning?  I’ll occasionally prune for hire, my skills were developed over decades of practice and observation and my array of tools have grown with experience, too.  

Primitive inherited tools that came with my orchard ..evolved into pole pruners, orchard ladders, 3-way filed pruning saws and a small chainsaw with it’s original bar traded for the smallest length for better maneuverability within a tree…  I’ve even favorite gloves and glasses 

But first and foremost came the experience; not only personal practice on ‘expendable trees,’ but books, extension service pamphlets, pruning seminars (which I’ve now presented), combing tool departments, orchard tours and the guidance, advice and wisdom of their owners.  Lots of people ‘prune,’ few ‘fine prune.’  And fine pruning is what it takes to enhance the production of a fruit tree.  

Having planted a menagerie, including persimmons, figs, grapes and kiwi, each have their specific characteristics; it took a decade to figure out how to deal with my fig trees alone.  Maybe I finally ‘look the part,’ and feel trusted by those sizing me up for a job … but it took a short lifetime to get there 

Not trying to discourage you, there remains a serious lack of ‘fine pruners,’ orchardists who know how to thin to the edges - as opposed to lopping off or ‘heading’ an overgrown fruit tree…  The tools seem to fall into place, stuff that eventually jumps out at you once discovering their capabilities ..often by suffering with a less capable yet affordable alternative.
