Yes clubs are quite effective and a heavy well made one can break and crush bones even if you get hit in the arms,legs or any part of the torso the are not just head bangers as many people think. Clubs come in all shapes and sizes and are really fun to collect they are one of my favorite weapons.
Here is one that was used for personal protection by an American geologist during the 1920s-30s in Rhodesia while mining for copper.
