About the Boker Sleeve Dagger

The Boker History Knife & Tool Sleeve Dagger recreates a clandestine British Special Operations Executive design forged from a single piece of GCr15 steel. Its vintage stonewashed finish and compact triangular profile make it a unique addition for collectors of historic military implements.

What is the historical origin of the Boker Sleeve Dagger?
The Boker Sleeve Dagger is modeled after clandestine equipment issued to the British Special Operations Executive (SOE) during World War II. Historically referred to as a bodkin or nail dagger, this compact tool was originally developed for undercover agents requiring an unobtrusive backup piece.
What steel is used in the Boker Sleeve Dagger?
The Sleeve Dagger is machined from a solid piece of GCr15 high-carbon tool steel. GCr15 is chemically analogous to 52100 bearing steel, providing high structural strength and impact resistance. The knife is finished in an antique black stonewash that evokes vintage field equipment.
Why does the Sleeve Dagger have a triple-edged blade?
The triple-edged triangular profile provides maximum rigidity and piercing capability in a narrow footprint. This classic bodkin geometry resists flexing under thrusting pressure while keeping the 3.5-inch blade compact and lightweight.
How do you carry the Boker Sleeve Dagger?
The dagger comes with a period-inspired leather pouch sheath fitted with an adjustable retention loop on the back. This setup allows the sheath to be secured along the forearm, strapped to the lower leg as a boot dagger, or mounted to gear straps.
How should GCr15 carbon steel be maintained?
Keep the GCr15 steel clean, dry, and protected with a light coat of mineral oil or knife wax to prevent rust. Because it is a non-stainless high-carbon alloy, routine cleaning after handling will preserve the finish and prevent surface pitting.
