Morihei is a Tokyo based company that is owned and operated by Mr. Oguro. At somewhere between 75-85 years of age (can never tell or ask..!) he is a great sharpener/polisher in his own rights and has been running his shop for over 5 decades in Tokyo servicing many locals with natural/synthetic stones as well as kitchen and woodworking tools. 

Kiyomitsu from Morihei is a budget-friendly line with the ease of maintenance and a good fit and finish. 

A petty (utility) knife probably gets used most often after your all-purpose knives. It can be used to cut small fruits, vegetables, and even some smaller cuts of meats (any many many more things, like cutting through plastic wrapping from a grocery trip!) If you have one, for a quick meal for two, you may just get it done without a chef's knife.
