I carry a small penknife in my handbag it has a 1953 farthing in the handle and is also a keyring but I dont have it with my keys .It was my Dads and he used it to peel the skin off apples.I would never think of using it as a weapon but it does come in handy at times.Its only 2 inches long when open ( the blade is 1 inch.) ,am I breaking the law?
