That's really vague.
If you're asking which you should buy, they are pretty different knives in some major ways: cost & steel being the most prominent. Mark has a Takeda 210 petty on closeout http://www.chefknivestogo.com/ta21pe.html
- $250 for AOS! His sasanoha is going to be considerably taller then the Kono pettys you are comparing it to.
The Kono's you proffer are as you know carbon : stainless.
Whats the question?
