I too see more, and appreciate more, of this carving style having read this Master Class Tutorial thread courtesy of Clive's generosity and expertise. Random thoughts on re-reading this thread:
On Judy's comment, I always let my dog smell my netsuke. Dogs have thousands of times the power of human smell. I watch her face and try to imagine all the smells of Old Japan that she smells . . . another way to appreciate what Judy said so well above.
I read long ago that Michelangelo reputedly said that, what he does as a sculptor, is to visualize the sculpture within the material, and then keep removing slices until the sculpture inside is revealed. I keep thinking of that as Clive explains the process.
The comparison to Cubism is stunning when you think about it.
The single cut (not single knife) style of Ittobori is one take on that concept, but in three dimensions instead of two, as in Picasso's masterwork, above.
Wishing we had many more threads like this one - we are at our best here.
