I Play Role-playing in Souls-based Games

I really don't understand why the protagonist chooses to buy a switchblade? Neither an ax nor a hammer are more useful than this. Look at the real world, it is difficult to kill a dog with a knife. Not to mention otherworldly beasts. A knife is useful for stabbing vital parts. It's useless if it pierces the bone. Nowadays, the protagonists of novels like this are all social animals. Once the weirdness revives or participates in the weird game, everyone becomes a weapons master. The plug cover is like inserting tofu. When I think about how hard it is to chop the fish head in the kitchen, it's quite counter-intuitive.
