Blade Type Information: 1070 High Carbon Steel

10 Series Carbon Steel is a designation for plain carbon steel--meaning steel with carbon added and nothing else. The number 1 represents carbon and the zero means that there are no other elements present in the steel. The next two numbers show the amount of carbon that's been added to the steel alloy, so 1070 would equal 0.70 percent of carbon added to the steel. Any steel with greater than around 0.6 percent and less than 0.99 percent carbon added is designated as high carbon steel.

High carbon steel offers a good balance of durability and ease of care. Because of this, it is a common choice for cutting tools, drill bits, weapons and knives of all types. The higher carbon content produces a harder, tougher blade.

Because it doesn't have inclusions to help take impact, weapons made of this material also have a low to medium edge retention that is in part dependent on the hardness of the steel. However, because of that same lack of inclusions, this steel is very easy to sharpen and will take an extremely sharp edge. The steel's lack of the other metals that are contained in stainless can increase the chances of corrosion, but this can be reduced with proper blade care.

In general, 1070 High Carbon Steel is a great choice for rough use weapons. Blades made of this material require slightly more care than some other metals, but because of their composition that care is easier and more affordable.

Handle Material Information: Ballistic Polymer

Ballistic Polymer is the combination of polymeric compounds, elements and processing procedures. The result of this process is a material that is:
  • Lightweight
  • Weather proof
  • Resistant to rust, temperature, and UV rays
  • Noncombustible
  • Environmentally safe
  • Can be manufactured in various colors

Rockwell Hardness: HRC 55-60

The SW671 Extraction and Evasion Tomahawk has a Rockwell Hardness of HRC 55-60

Stanley P. Rockwell inevnted the Rockwell Hardness Test in 1919 while working as a metallurgist in ball bearing plant. Rockwell wanted to measure the uniformity and hardness of inner and outer rings on which the ball bearings rolled. He designed a device that could measure hardness accurately and quickly.

The American Society for Testing and Materials (ASTM) standardized a set of scales for testing Rockwell hardness values. Each scale has been designated a letter and corresponds to a different group of materials. Scale C is used for steel, titanium, deep case hardened steel, hard cast irons and other materials harder than scale B 100.

Knife blades and other steel hardened tools are made from metals that match to the Rockwell C scale. Most blade makers display the hardness number as "HRC xx" or "HRC xx - xx" providing a range, where "xx" indicates a Rockwell hardness number. Not many blades measure over HRC 70. Most functional blades rate somewhere between HRC 56 and HRC 63.

Generally, blades with a lower HRC number don't hold and edge for long under demanding use, but they are easier to sharpen. Blades with a higher HRC value stay sharp for longer, but are more difficult to sharpen. As an example, stainless steel has a HRC higher than carbon steel, but it is also more difficult to sharpen than carbon steel.

Company Information: Smith and Wesson

Smith and Wesson is well known for its reputation as a leading innovator in firearms. Founded in 1852, the company had created the world's first repeating pistol with the invention of lever action and able to use their design of a fully self-contained cartridge. They then invented the rim-fire cartridge, bringing about another world first; a revolver that could fire this self-contained cartridge. To maintain their position of firearms superiority, they continued to lead the way in innovative technology in the firearms industry.

Smith and Wesson also designed the Model 3 American; the world's first large caliber revolver. These were subsequently sold to the United States Cavalry and to Russian government in the 1870s. Later, the company created hammerless revolvers which can still be found in their line today. Many military and police personnel have carried the Smith and Wesson .38, also known as the Model 10. They went on to introduce the .357 Magnum, the Model 39, the .44 and the Model 60.

In addition to firearms, Smith and Wesson created a line of tactical weapons, including tomahawks, knives, and axes. These are designed with the same precision and quality that they have put into their firearms.

The line of knives they created was designed by John Wilson, Roy G. Jinks, and Blackie Collins. Smith and Wesson has developed over 250 tactical knives, throwing knives, tomahawks, and hatchets, with the manufacturing done by Taylor Cutlery. These tactical tools are designed for a range of users, including hunting and outdoor enthusiasts, police agencies, and fire departments. Smith and Wesson knives, tomahawks and other bladed tools have one of the best warranties in the industry; warranted for the life of the buyer against defects.

For under $100 you get a fantastic urban tool. Thick steel all the way around, sharp right out of the box, and a nasty spike. The only thing that didn't impress me was the sheath, but oh well.

3.5 'hawk rating above is misleading. People purchase this as a woodsman t'hawk, or a tactical t'hawk, and are then disappointed. There are lighter, faster tools for such purposes. This is not a throwing, either (although, I suppose you could). This is a purpose designed/driven 'hawk, as the name implies. "Evasion?" If I had a good knife I would lose the t'hawk and travel light and fast. Extraction, breaching, demolition is where this 'hawk shines. Full tang 1070 (tougher than your mother-in-law), no weak points to fail, like handle attachment. Keep on in the truck in case you come upon an accident scene where folks are trapped inside their vehicle, or trapped by rising flood waters, or your neighbors are away, their house is on fire, and you can hear the dog scratching at the door trying to escape. Keep one in the basement to extract your family from tornado/hurricane/earthquake debris. Afffordable. Excellent 5 t'hawk rating for its purpose.
