Scorpion Knives

Scorpion Knives

Scorpion Knives are manufactured by Samuel Staniforth, a company founded in 1864 in Sheffield, England and steeped in the tradition of producing the highest quality knives for professional users. Scorpion Knives are used in the deserts, jungles and urban environments of the world by both military and tactical forces, as well as being highly sought after by knife enthusiasts and serious collectors.

Laser cut from the highest quality steel
 
Each Scorpion Knife starts out being laser cut from steel that is specified by us so that we are certain it will perform the duty it has been designed for. Steel always has a small carbon content, usually less than 0.2%, but by increasing the carbon content the steel is hardened which improves its ability to take and hold an edge. However this is at the expense of toughness (the steel can become brittle) and so by adding other alloying elements to the steel we are able to alter the properties to achieve the desired result.
 
The main elements and their effects are:
  • Carbon: Present in all steels, it is the most important hardening element and also increases the strength of the steel. Our steel is greater than 0.5% carbon, usually referred to as "high-carbon" steel.
  • Chromium: Added for wear resistance, hardenability, and corrosion resistance. Steel with more than 13% chromium is usually referred to as "stainless steel”.
  • Manganese: Aids the formation of grain structure and contributes to hardenability, strength and wear resistance.
  • Molybdenum: Prevents brittleness in our blades so that they hold an edge better.
  • Nickel: For strength, corrosion resistance, and toughness.
  • Silicon: Contributes to strength and makes the steel more sound while it's being manufactured.
  • Tungsten: Increases wear resistance.
  • Vanadium: Contributes to wear resistance and hardenability and helps produce fine-grained steel.
Heat treated to produce exceptional properties
 
The heat treatment of our blades is also a crucial part of the manufacturing process and one that is very carefully controlled. Heat treating is used to impart special qualities to the steel such as the hardness, strength and ductility.
 
When heat and subsequent cooling are applied to the steel, the physical and structural properties are changed. As different steels have different chemical compositions, so changes in physical and structural properties take place at different, critical temperatures. Depending on the temperature used, these changes can be a change in grain size, increase in toughness, removal of internal stresses, or formation of a hard surface on a ductile core.
 
In addition to changes induced by heat, the rate and method of cooling have an effect on the structural properties. For example, a rapid cooling will produce steel with a hard structure while a slow cooling will produce the opposite effect. Our heating, cooling and tempering processes are all closely controlled to produce the optimum knife blade for the tasks it will be undertaking.
 
Ground to perfection
 
There are a number of grinds available, such as hollow, flat, chisel and convex, depending on the final use of the knife. We choose the most suitable and then grind each blade by hand to exacting tolerances. We are masters of a number of complex blade grinds which you will see in some of our knives.
 
An exquisite choice of handles
 
The handle is as important as the blade and we offer the finest materials, for grip, comfort and durability. So whether your preference is tough rubber, exquisite linen Micarta or hardwood, for many of our knives the choice is yours.
 
Durable nylon or bespoke leather sheaths
 
Last but certainly not least, we have a range of sheaths in both nylon and leather. Our durable Nylon / Cordura sheaths are designed and manufactured by the renowned BLACKHAWK! company in the USA. BLACKHAWK! was founded in 1993 by former Navy SEAL Mike Noell and his meticulous obsession with quality has made it the ops gear of choice for Special Operation units worldwide. For the ultimate in leather sheaths we have commissioned the legendary English leather craftsman Ben Orford to design and handcraft a unique selection for Scorpion Knives. These sheaths are available either as standard or as an option on many of our knives. For the discerning knife collector, we offer high quality wooden presentation cases which can be engraved on the lid with your choice of inscription.
