About Kness Mfg. Co. A multi-talented entrepreneur, Austin Enos ”Brick” Kness had a knack for building tools that would make any job he was working easier. Whether it was a pruning saw for his days in a Washington orchard or a light bulb extractor for his days as a janitor during the depression, Kness had a knack for finding an easier way to do things. It was on one job that Kness was faced with emptying and replacing numerous mouse traps every day. To cut back on the mess he had to clean up, Kness conceived the idea of the ”box” trap. He built the first trap from a square oil can, a tobacco can, a spring from a curtain rod, and the wood base from a crate. Kness captured five mice in his trap the first night. His co-workers encouraged him to seek a patent and in 1927, Kness Mfg. Co. was formed and Kness began manufacturing the Roto-Bow tree saw and the Ketch-All Automatic Mousetrap. Every Kness trap is still made in the U.S.A and each one is hand-tested at their facility in Albia, Iowa. Made of durable galvanized steel. Catches multiple mice in one setting. Includes no bait or harmful chemicals. Easy to use and highly effective. Made in the USA – every unit is hand-tested. Dimensions: 9.25L x 7.25W x 5.5H in..
