The surname Kolb originates from the Middle High German "kolbe", with various meanings. The main sense is a mace – a heavy medieval war club with a spiked or flanged metal head, used to crush armor, or a cudgel – a short heavy club with a rounded head used as a weapon and part of an official’s insignia. It may also be a house name – there is a record of a house named Zum Kolben in Strasbourg.
