My father had a contract with this company located in Havana, Il to make knife handles for their knife blades. In late 50's when my sister and I was 11 and 12 yo. Old File knives always in our arsenal. Used what I call a hedge knife with long handle straight blade and short handle corn? knife. Long handle with curved blade only one from outside family

purchased at flea market. After father passed found gal oil tin with many blanks and  boxes of handles. All blades unstamped with factory logo. Some knife blanks are super flexible and retain shape after being flexed 90 to 180 degrees. Also found 50th Anniversary brochure of kitchen cultery and also price list of late 50's. May post later. Changed profile to match forum. Grinder used regularly. Butcher  lock has all Old File knives
