A 24-page booklet titled “A Story of Victor, “ published by Victor Insulators in 1945 stated: “The war gave impetus to the development of the chinaware business. Orders for great quantities of rugged cups and bowls built to military specifications have been and are being delivered to the Army and Navy.” The thick-walled hammer mug was suited for army wear and tear and navy ships favored their weight since it prevented tippage. Their indestructible nature was not overlooked by restaurants and soon, they became as synonymous to diners as the salty waitresses who poured coffee in them. Wandawega gets chilly in the mornings so we like to slip our hands around the curves of our mugs for warmth. Oh, and why is it called a hammer mug? Because weighing in at over a pound, it is literally built sturdy enough to pound a nail (although we don't suggest this use).
