Just wondering what peoples opinions are on either obtaining curved, straight, or both types of concave cutters? In short I understand that the curved cut gives a cut that causes the tree to heal much better, but if this is the point of them then why get the straight one?
I am probably going to look at getting a pair of knob cutters too, although I may not use them much I'm presuming I'll want to have them there for when they are needed.
Was there any other tool you guys would particularly suggest a beginner to get his very dirty hands on? I currently only have 6 trees in my possession (I know you're all impressed

Thanks in advance,
Pearcy.
