On the other hand, you should always customize your medkit for the emergencies you're most likely to find in your environment. I don't know what, exactly, Penny is trying to account for there. Whether it's gunshots from Earl (or, most likely, NDs from other Tranchers), or farm accidents. Either way, a fully stock medkit like that looks more like it's for show than something acquired with much thought put into it. And you're correct, some shears would be very useful there. Trying to cut through denim without good shears is hell.
