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. 

Akifusa’s mission from the start has been to supply conscientious cooks and knife enthusiasts with the tools they need to do their best work. Collaborating with a roster of blacksmiths and craftsmen (including Ohishi) across Japan, Akifusa offers a wide range of knives for any budget.

A kiritsuke-gyuto is a chef's knife with a slanted tip from a traditional single-sided blade called a kiritsuke. It is essentially a chef's knife with a twist. It serves the same function as an all-purpose knife, and although some swear that the accentuated tip makes it easier to execute fine cuts, we find that the k-tip mostly offers aesthetic power boost (rough guess 50%).
