Just approximate, guesstimate ages. Go by the logo’s, blade material and construction. Early knives typically have a number of smaller handle rivets (5 or more). Harrington knives from the 20th Century (pre ‘33) have the arched Harrington Southbridge Mass logo on the blade and have larger rivets (handle pins) that appear to be nickel silver. Later knives have brass rivets.
I don’t know a lot about the Russel knives, but early ones are marked on the ricasso, “J. Russel & Co, Green River Worx”, with a diamond logo. it’s a safe bet it’s a more recent knife if the blade is stainless (like my cleaver) and it has larger pins. If it’s marked Dexter - Russel, you know it’s post 2000.
I’d guess your large Scimitar is from the late 40’s - 50’s, but that’s just a guess.
I here Old Hickory a lot, here is an Old Forge by Case XX Quite like the Hickorys were.
Ontario Knife Company still puts out a line of Old Hickory knives. For good, solid, everyday working knives they can't be beat. I just got a 5.5" Hunting Knife and sheath, and just ordered one of their Trout and Bird belt knives. They won't win any beauty contests, but they'll do any job a knife ought to do and cost anywhere from $15 to $35 or so depending on the model.
marked ECKO forge USA with a stamp that resembles a German company stamp meaning twins.(zwilling) maybe? got it from my late MIL's house last night. very sharp and probably very old. touched up the edge and you can almost shave with it. blade is 8 1/2". Lee
I've understood that health regulations prohibit wooden handles on cutlery used for commercial food processing and preparation - too many places for bacteria to hide. Molded plastic handles seem to be the norm. Is that correct?
