ThEoRy indeed that Gesshin looks killer but at five bones I can't justify it as my first Deba. Others have commented that you are the man to consulting about the Deba. I am honored to have your feedback.
So I've asked Keiichi from BluewayJapan to sell me a 195MM in Blue #2 with magnolia/black buffalo ferrule octagonal handle and saya. He might be able to do that knife for me for around $200?
What do you think about that configuration? Also seems like most of the Deba's come with round or d handles. Why is that? Cost? Would be octagonal be more advantageous? thanks again for your feedback.
