Yes. Investing in more than two or three tools up front isn't really worth the money.
A good concave cutter as a first tool is a great investment. $50 will get you a solid medium-sized concave cutter. "Regular" tools like scissors, hardware store wire cutters, Chinese restaurant chopsticks (as a root hook) etc. can be used instead of buying those things right away. Knob cutters, two sets of shears, trunk splitters, root scissors, jin pliers etc are frosting, really. They make jobs easier, but aren't critical.
Let's all play nice gentlemen. No need for pecker measuring up in here
. The real question after reading your answers: so as a matter of fact you guys only normally use a few 2/3/4/5 tools on a daily basis... those are the staple and everything else is just frosting... right?
Sorry if I came across defensive, I really didn't mean to.

I've not got anywhere near enough trees yet to be using all the tools that I have, but its nice to have for future.
