Pocket knives are handy and compact tools that can be used for both general and self-defence purposes. Although small, pocket knives can be quite strong and extremely durable whilst featuring an ergonomic design. This multi-purpose tool can help you open boxes, letters and peel fruit while at home or when out fishing, camping or when scraping away rust or wet glue. You basically have the capability of a kitchen knife in your pocket. But aren't they the same thing as Swiss army knives?
