Hi Guys,
What's your view on purchasing a rounded concave cutter? ( as a beginner? ) ( it does the same job as a knob cutter and branch cutter I've heard)

If you don't have a regular concave cutter it will be best if you get one of those first. While the rounded (or spherical) concave cutter is a nice tool it is very hard to sharpen. As a beginner the learning curve is 4th dimensional problem and you might mess up a tool or two trying to cut a branch larger than your cutters can take. All in all make sure you have the following tools before "branching" into the more specialty tools:
* Bonsai Shears (8.2" - 208 mm)
* Jin Pliers (8.2" - 208 mm)
* Concave Branch Cutters (8" - 203 mm)
* Wire Cutters (8.2" - 208 mm)
* Knob Cutters (8.25" - 210 mm)

Nice use of the word branching and thanks for your response. What is a good brand of tool? I am avoiding the yellow label chinese tools but what about Ryuga? Or would you suggest Japanese tools?
I would like to perhaps buy a better set when I have the experience and when I have more trees .

My Favorite "Beginner-Intermediate" set is Roshi Stainless Steel. Advance or Professional brands that I am familiar with are Masakuni and Koyo. I have never used Ryuga.

I've now obtained all the tools. Some are chinese, Some are Japanese but I'm happy with them. Thank you for all the advice.
