Yep, and one might try
this site too for these at a bit lower price.
Haven’t been around like
@rockm , but my pair of knob cutters is cleaned and oiled with all the other tools, but never used.
However I’ve seen a lot of tools used for things they ”aren’t“ supposed to be used for, sometime innocuously, sometimes to the detriment of the user… and others never used for what they were ”supposed” to be used for.
Using concave or knob cutters for a ‘finishing cut’ on azaleas can leave one with a wound that will take a long time to heal… if ever, and not look right for a really long time on most azaleas we have….
Here’s a photo of an example on a big satsuki. See center part of the image and just to the left too. Concave or knob cutters were used to create a ‘finishing’ cuts on this Secchu no Matsu... much like one uses on maples etc. Yet Azalea bark is so thin it closed up over the wound and preserved the concave wounds. These cuts were made years ago.

However… In an expert case counter to this situation, I have seen knob cutters used by a Japanese master on larger, older satsuki for all kinds of branch cutting and carefully made finishing countour trunk cuts. On one of his videos he mentions hus knob cutter tool is used to contour the wood to create an effect like the tree trunks in nature on old trees.
His videos are posted on YouTube…. Bonsai Master
Hope this comment isn’t considered a thread ‘hijack!’
