Swing-A-Way can openers used to be made in St. Louis, MO. After the family sold out they finally ended up being made in China. The quality went away. I thought I came across some info that the possibly former St. Louis factory/equipment was acquired by someone else and that a new company was making can openers with the same quality again but I can not document this now. Is that true? Is there another brand name selling them now?
St Louis, claims to be only one made in USA, Seems to fit time-wise.
per one of several catalog sites (http://www.sierravalleytrading.com/JOHN-J-STEUBY-CO_c_815.html)
John J Steuby Company of Hazelwood, Missouri, has purchased the equipment used to manufacture the original, MADE IN USA, SWING-A-WAY can opener and now uses that equipment to manufacture the EZ-DUZ-IT can opener.
