That single blade jack is unusual as it is a SINGLE BLADE knife! You don't see them often -
especially from Colonial!! Nice, Mike!
The old cell handle knives with the tip bolsters that are stamped U.S.A. or unstamped are
difficult to pin down the maker. (the knives with integral tip bolsters)
The main culprits of these knives are Colonial, Imperial, and Prov. Cut Co.
I believe Imperial actually held the patent on the integral bolster/liners. (or so I was told)
To determine the maker, most of the time you'll need a knife that IS stamped with the company
name for comparison. There are several things to look at. Look at the distance from the end of
the pull to where the clip starts on the blade. Compare the shape of the tang kicks. And MEASURE
the distance from the rocker pin to the other pins; scale pins and pivot pins. Blade thickness also
tells a story - however it doesn't necessarily mean it is from a different company.
Here is a butter & molasses stockman "handle" I picked up in hopes of finding replacement blades for.
No reason to open the knife to show the blades cuz there's not much left. It DOES have the arched stamp.
My first shot was the 4" stockman. This knife came from a house in R.I.! The scales are beginning to gas
out - but the blades cleaned up nicely. I had no clue this was a 4" knife when I bought it and I DID buy
it just for the blades...
Second shot was the little 2 blade jack... turned out that the blades are the correct length BUT there
thinner than the blades I need...
Looks like "Goldie Locks" will have to wait for another knife with full blades to show up. I'd feel kinda
silly asking the sellers to mic the blade thicknesses.
I've got a camouflage knife, but I can't find it.......
..... cardboard addicted.....
