Imperial identification question

Schrade Cutlery Company was founded in 1904 by George Schrade, and his brothers Jacob and William Schrade. In 1946 Imperial Knife Associated Companies, (IKAC; an association of Ulster Knife Co and Imperial Knife Co) purchased controlling interest in Schrade Cut Co and changed the name to Schrade Walden Cutlery. In 1973 the name was changed to Schrade Cutlery. In 2004 Schrade closed due to bankruptcy.

This forum is dedicated to the knives that are the legacy of this company. This forum is not the place to discuss the replica knives currently being imported using the Schrade name.

Imperial identification question

Post by KenHoward » Sun Nov 12, 2017 5:43 pm

Hello everyone...Newbie here...

I am a collector of strictly pocket knives, with an affinity for the cheapos, haha. Can someone answer a few questions for me? I know I have an IMPERIAL Ireland Trapper with a Turkish Clip and Pen blades and a shell handle, but want to know more...
Model?
Blade material? Stainless?
Bolster material? I think they are stainless caps...not sure
Liner material? stainless?
Pins? can't see them
Year(s) produced?

Yea, like i said...I like the cheapos and cleaning them up.

Thank You

Hi Ken,
Welcome to AAPK! ::welcome::

It appears you have a Jackmaster #801. It should be 3-1/8” in length when closed. If you look at the ends of the knife on either side is a tab that holds that handle half in place. Each handle half is a piece of pressed sheet metal so that it appears to have a bolster and handles and some of them even appear to have rivets. The handle material is a piece of colored plastic wrapped around the handle half and held in place by being pinched between the handle half and the liner of the inner portion of the knife.
The inner portion of the knife functions perfectly well with both handle halves gone, indeed you often see them this way at flea markets. Inside are two springs, two blades and two liners, (one on either side, and sometimes they had a center liner). The pieces are all riveted together to form the inner portion of the knife, which is really the heart of the knife. The addition of the handles just makes it look more like a knife and definitely makes it more comfortable to use.

The blades are probably carbon steel as well as the shell handle, at least most of them I have seen are carbon steel. It is likely they made some in stainless steel prior to their closing.

Imperial bought the rights to a shell handle patent and begin producing shell handle knives circa the mid-1930s. They use the name Hammer Brand, which had been a high quality brand of knives, made by New York Knife Company. They did use good quality steel and they were able to sell these knives for a fraction of the price of a handmade slip joint knife.
The original concept of a shell handle knife was developed in Germany in the late 1800s and patented it around 1901 in Germany. I have attempted research for German shell handle patents prior to 1900, but it is nearly impossible to track them down, even with the assistance of a German knife expert. He explained to me that patent records were destroyed in World War I and World War II and he was unable to find copies of any patents.

Basically the design of your little knife originated in Germany, was modified somewhat and re-patented in the USA and used by Imperial. Imperial Knife Associated Companies was formed in 1947. It was a consortium between the Schrade Walden, Ulster Knife Company and Imperial International Corp.
In 1978 IKAC purchased the Jowika factory in Listowel Ireland, where your knife was made. Jowika had been one of the original German companies who made shell handle knives.

The Imperial Schrade Corporation factory in Listowel Ireland closed in 2003 about a year and a half before the bankruptcy and closing of Imperial Schrade Corporation in July 2004.

Thank you so much for the information! I love hearing about the history of the knives I get for free or dig up at a show for a few bucks. I will clean this one up and print off your reply and put it into my collection. Much appreciated.

This particular knife was made shortly before the noon lunch break. Ken is correct about Tuesday. Dale's [Orvet] answer is a classic. Awe inspiring to an accumulator like myself.
