The Luffy design is the same head as
@chazt “woody”. Seeing this I thought maybe this was the intended blade.
Currently, the Kai Kasho website and brochures have no references to Luffy. I also learned a bit about the scalloped Kai blade profile vs. the non-scalloped. The gist is scalloped bladed models were designed for hair styling. Apparently the scallops aid in lifting the hairs being styled. Sound familiar? So,
that design feature, with reduced blade exposure
and the lip on the blade edge combine to create a reduced blade feel experience for a person who wants to shave his face with the same instrument.
