Couple markets buttering knife
Anne and Joe McMahon of Wilton have begun nationwide marketing of their invention, the ButterOnce® corn buttering knife. Last summer the product was in the Village Market and was launched July 10 on The Grommet website.
As a result of the ButterOnce knife, which was under development for two years, the retired couple started a product design company, J&A Designs, in 2015. Their motto is "to create and market simple household products that simplify and enhance everyday life."
The product has also been sold in more than 40 states.
