These buckles are left over from a county fair, they measure approx. 3” W X 2” H, knife slides into place and is held by a knotch that it clicks into. Super cute and handy on the farm! The knife itself , extends to 5” the blade is 2” long. Fits belts up to 1 1/2” wide, I no longer do the county fairs and am just trying to make room, buy 1 or make me an offer for the whole lot! Please double check the size people always commented that the photos made them look bigger than they are.
