I'll be honest, I didn't give them nearly the comparison they deserve or that a forum like this would expect. OOTB I knew the Kagekiyo would smoke the Ashi for the ways I use a petty. Stopped in the office off the clock to help with some quick prep and give it a test drive, and the Ashi's fate was sealed.
The thinness and flex of the Ashi has it's uses, and in a perfect world I'd keep both. But I'm kinda in the
@panda camp: no more than five knives in my bag, and no space for a mostly redundant knife that performs worse on the board.
