Innovation at Real Steel Knives

Explore the cutting-edge innovations behind our designs. At Real Steel Knives, we are constantly pushing the boundaries of knife craftsmanship to bring you the latest in performance, structure, ergonomics, and materials. Discover how our engineers and designers work together to redefine the future of EDC, bushcraft and tactical knives.

ATS for Slip joint: Slipjoint too stiff or too weak?

ATS stands for “Adjustable Tension System” and is a system specially developed for slip joint folding knives that solves the problem of spring tension. Its principle is to change the pivot position of the back spring by rotating the eccentric (the spacer sleeve in the middle of the handle), thereby changing the spring tension. There are three levels of adjustable spring tension: high, medium, and low. Operating the ATS is extremely easy. All you need to do is turn the middle screw clockwise with a wrench. The stages alternate in the order 0-1-2-3-2-1-0, and each stage corresponds to a clear position. The Ventus is our first knife model to use the ATS.

G10 Back Spring: Want a back spring that matches your handle color and is lighter too?

G10 is known as a handle material, but using it as a functional part is a bold innovation from RSK. It has two main features: 1. Color (customization). The color of the back spring should match the handle or you can freely adjust the color. 2. Lighter weight. A steel insert is embedded where the back spring contacts the blade to ensure long life. RSK has carried out extensive strength and durability tests on the G10 back spring so you can use it with confidence. The first models with G10 back springs were Luna, Stella, and Solis, which we called the LUX series.

Integral Spine: Looking for the strength of a gunbolt with sleek, smooth design? 

The folded handle is made from a single piece of sheet metal and replaces the steel liners of the traditional structure. The advantages are obvious: the stable structure, fewer screws are required and the overall weight is lower. RSK's first folding knife with a folded handle is the Sacra, which is equipped with Crossbar Lock. This locking system places extremely high demands on machining accuracy and also results in the uniquely smooth feel of the Sacra. This one-piece structure is versatile: linerlock, backlock, slipjoint, crossbarlock, etc. are options.

Interchangeable Scales: Want to show off a new side of your knife?

The ability to replace the handle scales without affecting the construction is the wish of many fans, which RSK has now responded to. RSK's interchangeable scales have two main features: 1. After the scale is removed, the knife can still be used. 2. You only need to tighten/loosen a single screw on one side to change the scale. The first knife with this creation was the RB-5. RSK offers G10 in various colors, as well as titanium and copper scales.

Creative Ideas & Competent Implementation

  • Ideas for more safety

    For additional safety in use, RSK has unique solutions for various locking mechanisms, all ocks must be activated or deactivated manually.
    Beta Plus: on Frame Locks since 2014.
    Multex Alpha: for Lock back since 2014, it's located at the lanyard hole.
    Slider Lock: safety lock of the button lock to prevent accidental activation.
    101 Safety: first used on T101, suitable for Liner Locks, functional and unobtrusive.

  • AUTOMATIC Safety 

    The safety on Exorcist is automatically activated when you open the knife, so you have extra safety right from the start. When you close the knife, pull the slide down and simultaneously unlock the frame lock to release the safety.

  • Symmetrical steel insert

    The Evolution uses a replaceable steel insert in the lock bar position, which is symmetrically designed and equipped with two detent balls, thus doubling the service life.

  • Duet of Detent ball

    RSK uses two detent balls on the Harrier Frame lock. The ceramic balls of different sizes give this knife a special fun when opening and closing. It requires a high level of manufacturing precision.
