So does anyone know which company actually manufactures these knives?
Colonial's site lists Suite A, 61 Dewey Avenue, Warwick, RI, as the company's address. That small office site, with its seven employees, is surely not a factory.
Another address pops up in some listings: 287 Oak Street in the depressed Olneyville neighborhood of Providence. That address is listed for a portion of a multi-tenant two story brick building, and is the same address as listed on line for Appalachian Company, a furniture retailer, Regal Reality, and Nn1u Radio Club, No signage identiifies it as a Colonial Knife site. Mars Plastic and a company called Clear Choice are in the same building at other Oak Street addresses.
The old Colonial factory, that closed in 1999, is apparently also in Olneyvills. The property is for sale The building is an abandoned wreck.
So Colonial has no manufacturing facility.
I can find no more information on Colonial.
As it happens, Colonial's website does not claim that the 2205 is made by them or in the U.S.A.
