Your plants don't care what brand of tool nor type you use or as Al
@Smoke puts it "They don't give a shit". I find that if you use tools properly, clean them, oil them, and keep them as sharp as possible, even inexpensive carbons...
If I had a bigger place I would display very expensive tools perhaps in a work space dedicated to Bonsai. I have many, stored, not to be sold, as they were gifted to me.
I don't use them... I have dropped and ruined enough of the less expensive stuff and I assure you the more expensive would have been ruined too
My 2 cents, your money...
