Nick, that is a wonderful early NYK Company Congress Pen! In remarkable condition given its age
That would be a grail type knife for most any serious collector!!
Here are two Electrician or Radio Knives. These are single blade screw driver-wire stripper lock back folders.
The top one is branded Red Devil S & H Co. New York. I posted this on page 808 of the Old Knives thread back
In Dec. Interesting story how it got the name Red Devil. Anyway it looks to be an Empire made Knife, at least that
is what Charlie suggested at the time.
I happen to be cruising one of my EBay saved searches and found the second one just recently at a very low BIN so
plunged in and bought it. The photos were not great but the description was promising. Turned out to be a stellar condition Empire Winsted CT. tang marked example with a nice etch. The etch is J. H. Bunnell & Co. New York.
Found this interesting information about the company on google
http://jhbunnell.com/bunnellcohistory.shtml.
The two are very similar but with the following differences. Different shields obviously, the Empire blade is wider
and about 1/8 inch longer (although neither blade appears used or messed with), the bolsters are different with the Red Devil bolster more squared off whilst the Empire bolster is more rounded, the nail nicks are different, the Red Devil
has Cocobolo handles that are much thicker or wider at the rear or butt end and the Empire handles although Cocobolo are much more narrow at the rear or butt end and finally the pin placement and the pin size on some of the pins are different.
So, is the Red Devil an Empire produced Electrician/Radio Knife? I guess the differences could be just be attributed
to evolution of design although they both seem to be about the same age I would say. Circa 1920s. What do you say if
you were guessing or know? Thanks!
