Guns, Bows, Shooting Sports, and Hunting Help me ID this old knife

[BigPapa]

I got this knife out of some of my great grandfather's stuff back in the early '70's. I can't find anything on it. It's just over 9" long with a 5" blade and the handle seems to be plastic. I can't see any markings on the blade. It's pretty rusty.

The only thing I can tell you is it looks like a diving knife. They usually have the sawback and plastic handles. It would also explain the rust. Try searching for the brand logo in dive knife suppliers. Unfortunately given the age the logo has probably changed, or the company is no longer around.

I took a few minutes when you first posted and tried to find something. I'm fairly good at finding info on the web but I failed on this one so far.

Will try again this weekend.

It may be a Diamond Ceramic blade and would be naturally dark in color.

Big papa, you are correct, it is an old knife with some rust on the blade.

Were there any stores your great grandfather liked to shop at. Many stores used to have their own brands of knives or guns. Like my Wards Western shotgun.

I believe wards was western field, Sears was Ted Williams. Before cable TV and the internet, a boy could look through the Sears/Wards catalog for everything he wanted. I still remember the big deal it was to go to the Portland Sears store. We would get a box of carmal corn from the candy shop. We didn't have any money back then and that was a treat!

This style of knife blade didn't gain popularity until the late '60s, and is a "survival" or "military" style blade. There were similar blades made earlier, but few. The black plastic handles are cast or injection molded in place it appears, with no rivets or sets, which would make it a cheaper brand of knife. Obviously high carbon steel as indicated by the rust, it is most likely a Colonial Knife Company product.... Most Colonial knives are made for other manufacturers, such as Buck, Sharp, and Old Hickory.....
