is a rare MK V dive knife most likely made by A. Schrader & Sons, Inc., of Brooklyn, NY during WWII. Schrader
and Morse were the two early makers of the MK V diving system. Their knives are highly collectible.
MK V Dive Knife became part of the MK V Diving System in 1929 and was included in the specifications first adopted
by the U.S. Navy in 1916. The MK V System was used until 1984. However, this type knife is reported to have been in use
in Europe and this country as early as 1915 and all the way up to the 1980’s so dating is iffy. In this case, we are relying
on the lack of markings to what is certainly an authentic MK V dive knife.
NO MARKINGS: This knife
and sheath carries no markings. Morse reports that their knives were marked during this period. However, an equally authoritative source,
DESCO told us the Navy specified the knives they were not to be marked during War
II. We don’t know which is correct, but maybe both are depending on the time frame. We do know that Schrader made
an earlier knife of a different design that was housed in flat sheath that had a maker’s mark on the blade.
The knife is designed to screw into the top 1″ of a cast brass sheath which is included using Acme
threads which hold it securely, and allows it to be easily and quickly removed. The upper edge of the knife blade has
saw teeth while the lower edge has a very sharp knife edge. This style knife is still in production today by
Morse and DESCO.
A rare A. Schrader dive knife for the collector or for use.

Reverse side of hilt and blade
Stains on sheath over normal patina of age
is in very good condition and tight. The blade has only a few tiny spots. It has been honed to a sharp edge. The
wood handle has most all its varnish which is still bright. The sheaf is missing it’s leather strap, and there
are some small dings from use. It has a dark to light patina overall, and looks like it may have been
wrapped in a fabric which transferred some of its pattern over the patina in what looks like a stain.
