Acme United acquired the Camillus brand in 2007, however we do not have access to the 135 years of history on Camillus knives produced by the original Camillus Knife Company. While we are happy to assist with knives produced after 2007, we unfortunately cannot provide assistance, service, or verify the authenticity on the older models.
Our recommendation would be to reach out to Rock Cutlery USA. Their phone number is 315-320-4122 and their website is rockusacutlery.com
If you are looking for warranty service or repair, please take your older Camillus knife to a local knife shop that may be able to refer you to a knife restoration specialist.
More information regarding antique Camillus knifes can be found on the Camillus website.
