Inspired by soldiers, the Soldier TSK-1 is the ultimate everyday pocket knife you will ever need to carry. The compact Soldier TSK-1 is designed with precision and detail that allows it to be extremely robust and versatile in every survival situation.
We wanted to design a quality compact tactical slide knife that can endure the toughest daily tasks and also thin enough to carry without notice. In other words, we wanted an all around awesome pocket knife that was fully concealable.
Military Concept: All of our Soldier products have a military design and tactical aesthetic. The Soldier TSK-1 is engineered to hold durability and functionality similar to military grade equipment.
Blade: The blade is split with a serrated teeth edge as well as a sharp edge. The sharp edge is perfect for thin sharp precision slices whereas the teeth is perfect for tougher materials like wood. The Soldier TSK-1 uses the "Great American Tooth" pattern much like in traditional crosscut tree saws. The pattern was designed specifically to saw and rake wood fibers. The blade is also perforated to allow cutting and slicing of materials to not stick onto the blade itself. It provides a cleaner sharper cut.
The Soldier TSK-1 cuts using the "Great American Tooth" pattern. Wood or other tough materials can be sawed and raked. The non-serrated part of the blade or precision cut blade is flat ground. We were looking into both options during the design process and concluded that a flat ground blade would be more versatile for most people's daily use of an every day carry.
The serrated part (teeth) of the blade, however, is a chisel ground. We designed the serrated part of the knife to be able to scrape flint or even split wood. The blade itself is very robust and the serrated chisel can be used to wedge and pry.
Although the knife is very compact, it was engineered to be very tactical. The versatility of both blade styles give it an advantage over every other small pocket knife.
Sizing: Discrete concealability is the definition of the Soldier TKS-1. The full opened length is only 115mm and when closed, it stands at 75mm in length, 35mm in width and only 5.75mm thick. The miniature size of the pocket knife means it can easily be hidden in any coin pocket or clipped onto keychains without notice.
Weight: The ultralight weight of the Soldier TKS-1 comes in at 2.1oz making it the world's lightest, fully functional, 440C stainless steel tactical sliding pocket knife.
Materials: 440C stainless steel allows Soldier knives to be one of the strongest compact blades ever created. Rated at 55-58 HRC the Soldier TSK-1 is extremely tough and will stay sharp for longer periods of use. 440C is a highly durable and corrosion resistant stainless steel. The Soldier TSK-1 can endure years of outdoor wear without extra maintenance to protect the blade from rusting.
Handle: The Soldier TSK-1 knife handle is heat treated 420C stainless steel able to achieve a 58-60HRC hardness scale.
Slide in/Out: The Soldier TKS-1 is a slide in and out lock. Safety was one of the main concerns when it comes to a knife of this size. We wanted the design the be suitable for beginners as well as intermediate knife experts. The lock is a push button lock. You can actually use the spine to scrap splint without the worry of it coming around when the blade is locked. This makes the knife design much more robust than traditional smaller blades which are just folding.
When the Soldier TSK-1 slides out, the button "SNAPS" into place to lock the blade from accidentally retrieving when in use. The user can feel and hear the tactile sound and click on the lock. To close, all you have to do is press the locking button to slide in.
While designing the Soldier TSK-1, we made sure to leave ZERO wiggle room. Once locked into place, the blade is completely tight and will not move. It was incredibly difficult engineering this, as the TSK-1 is very compact in size. We made sure to trial and error fractions of a millimeter to finally get the TSK-1 to hit perfection.
The Soldier TSK-1 is the world's smallest and lightest tactical sliding knife ever to be created.
In-depth Look of the Soldier TSK-1
All SOLDIER products were originally designed for ourselves. We engineer everything under strict quality and durability standards. It is our promise to provide a lifetime warranty for the TSK-1 Tactical Sliding Knife. If it ever breaks, send it back to us and we will replace it free of charge.
Our goal was to make the most compact, stylish, and functional sliding tactical knife ever created. With the measurements of 80mm in total length and weighing at less than 1 ounce, the Soldier TSK-1 is the perfect concealable everyday carry tactical sliding knife.

The following shows the design process of the Soldier TSK-1 from idea to production. During the design process, we had a few key elements we wanted to incorporate into the TSK-1. The knife had to be thin enough to carry discretely, however still big enough to be used as a functional knife. It also needs to be extremely durable.
The above pictures show the first sketches and concept design of the Soldier TSK-1. The napkin sketch of the knife was the first iteration and It gave us the very basic design look and length. Once we achieved the perfect look and tactical feel of the knife, we were able to create a CAD rendering.
Below is the first 3D print prototype of the Soldier TSK-1, this was not a functional prototype, as it is made out of plastic. The abs plastic is hard enough and just an early prototype to understand the overall feel, weight, and hold of the knife. Once we had the overall aesthetics of the knife down, we needed it to be fully functional in the following steps.
Once we had the 2D drawing, we were able to start making a prototype. We then adjusted the dimensions of the knife in CAD to create the perfect 3D model. We then use the 3D CAD model as a blueprint for the first tangible product.
In the second prototype, we managed to produce it out of real stainless steel. Using 5Cr13MoV stainless steel, we were able to achieve a stronger, more tactile, precise, and functional prototype.
Our third prototype, we added a precision grind onto the blade. We originally decided to go with a serrated blade "chisel grind" (meaning only one side of the blade was sharpened) because we were going to add a serrated section. The following final prototype shows a "flat grind" on the blade because it allowed both left and right handed users. It was ultimately more versatile. As you can see in the video below, we show the differences between the final prototype and the third prototype with different grinds on the blade.
