This series of highly functional rescue knives is dedicated to police, paramedic and rescue professionals, who do their best in their dangerous fulfillment of duty and often risk it all to save lives. These knives are equipped with all the necessities: glass breaker, belt cutter, carry clip, and corrosion resistant 440 stainless steel blades.
The Magnum Rescue Knives are fully functional and ready to use, but they have not been designed for the daily, demanding use of professional first responders. For professional users we recommend for example the models Boker Plus Savior or FKMD A.L.S.R. 2.
The American 440A is a decent starter steel. We use it widely in our Magnum series. It is not to be confused with the higher-quality 440B and 440C.
Aluminum is a soft and tough metal, it is very light and at the same time has a high strength. The metal is also recyclable.
It has been extracted for about 200 years, initially it was more expensive than gold. Through improved methods, prices have declined over the years, as aluminum is the third most abundant element on earth and the most common metal in the earth's crust. It usually appears to us as matte and silvery, but the surface of the metal is actually silvery-white glossy. However, since aluminum reacts with oxygen, a thin aluminum oxide layer is formed. This results in the matte appearance.
Aluminum is very popular in many branches of industry due to its specific strength (and at the same time low volume). Thus it is used especially where a small mass is important. A lot of aluminum is used in the aerospace industry, as well as in the automotive industry.
Thumb Studs make knives easier to open. They allow for the blade to be opened up with the thumb. The stud may be placed on one or both sides of the blade; some models have a thumbstud on the spine. Depending on the production process, the thumbstud can be secured with a rivet or screw. Knives with screwed thumbstuds can be easily retrofitted for ambidextrous opening without compromising their look and design.
The linerlock (alternate spelling: liner-lock) is a locking mechanism mainly used for one-handed knives. Knives equipped with this mechanism are usually called linerlock knives.
The linerlock was invented in the late 19th century in the United States and patented there in 1906. This early version of the linerlock could not be opened with one hand though. The first truly one-handed linerlock knife was only developed after the patent for the original linerlock version had expired. The one-handed linerlock knife was designed by Michael Walker, a US knifemaker. In the 1980s, he introduced an improved linerlock knife first called the "Walker Linerlock".
The special feature of this linerlock is the plate between the handles scales used to lock or release the blade. The mechanism derives its name from this plate or liner. The liner is slightly curved inward. In the front, it extends past the bottom of the handle scales so that it can be operated from the outside. Usually, the plate of a linerlock is made from very hard metal such as stainless steel or titanium, because it needs to hold the blade in place even under great pressure.
The linerlock mechanism works as follows: When the blade is closed, it pushes the liner to the side. When the blade is opened, it makes room for the liner pushing towards the inside and locking in place below the end of the blade. In order to release and close the blade, the liner must be moved to the side manually. Modern linerlocks, available since the 1980s, can be operated with one hand, which made this locking mechanism very popular.
