Oh, good, you listed all the ceramic knives separately.Speaking of which, those are knives and they can be thrown but they are not "throwing knives", so to speak. Throwing knives have a separate entry in Chummer under ammunition, like the grenades. (You'll notice that the throwing knives have ranges while the ceramic knives do not.) Since the throwing knives are ammunition you can add any quantity that you like instead of having to add each one separately like the ceramic knives. That would cut down on some of the inventory spam.A regular knife costs ¥20, which is the same as a throwing knife. It follows that ceramic throwing knives would cost the same as a regular ceramic knife (¥75), pending GM approval. Any reason you took the Autopicker at rating 4 instead of rating 6? It's only a ¥400 difference and the availability rating is the same. Ditto for the keycard copier. ¥600 buys you two extra dice, which is a good value.
