I am looking to get a cheap knife (under $25) for EDC for self-defense and general utility. I want something that is lightweight (2-3 oz) and around 4-4.5 inches closed. Wha are your thoughts and experiences with the Kabar Dozier Folding Hunter, Kershaw Chill, Bucklite Max folder the medium size, and the Bantam folder medium size. Also any other suggestions you may have.
