About this project
Inspired by the B-2 Stealth Bomber military aircraft, the B-2 Bomber Nano Blade is the last everyday pocket knife you will ever need to carry. The mini tactical B-2 Bomber Nano Blade 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 miniature tactical pocket knife that can endure the toughest daily tasks and also small enough to carry without notice. In other words, we wanted an all around badass pocket knife that was fully concealable.
Urban Military Concept: All of our Bomber & Company products have a military design and tactical aesthetic. The B-2 Nano Blade is engineered to hold durability and functionality similar to military grade equipment. Vincent Pilot Ng (Lead Designer) has had over 10 years of professional experience in product design. He has brought about other renown products to markets such as the Bomber Barrel Duffle Bag and Halo Belt.
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 B-2 Nano Blade 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 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 small, 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 B-2 Nano Blade. The full opened length is only 80mm and when closed, it stands at 48mm in length, 20mm in width (closed) and only 5mm 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 B-2 Nano Blade comes in at less than 1oz making it the world's lightest, fully functional, 440C black stainless steel tactical pocket knife.
Materials: 440C black stainless steel allows B-2 pocket knives to be one of the strongest nano blades ever created by mankind. Rated at 58-60HRC the B-2 Nano Blade is extremely tough and will stay sharp for longer periods of use. 440C is a highly durable and corrosion resistant stainless steel. The B-2 Nano Blade can endure years of outdoor wear without extra maintenance to protect the blade from rusting.
Casing Design: The B-2 Bomber Nano Blade Pocket Knife embodies a full redesign of the vintage SR288 stock casing. Originally, this discontinued casing was used for full-sized pocket knives ranging from 5 to 9 inches. The reason we have chosen this stock casing is because of its ease of use, comfort, and reliability in tactical use. Our redesign of the stock casing has given the body a tremendous upgrade in quality as well as addressed the original flaws that didn't make it a versatile knife.
We have upgraded the casing material to a heat treated 440C black stainless steel and shrunken the size dramatically to a miniature version similar to its older brother. In addition, we upgraded the blade material to 440C black stainless steel to achieve a 58-60HRC hardness scale.
Upon doing so, we were able to add the Great American Tooth pattern for "sawing" tougher materials like wood. Staying true to its size proportionally, the thickness of the casing comes in at 5mm. Ultimately, with the entire redesign, we were able to increase the overall mobility, strengthen the tactical utility of use, make it fully concealable by size, while maintaining a very comfortable hold and improving the military/tactical aesthetics of the entire pocket knife.
Folding/Locking: The B-2 Bomber Nano Blade is both locking and folding. 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 lever rather than 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 B-2 Nano Blade opens, the lever "SNAPS" into place to lock the blade from accidentally closing 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 lever to open.
While designing the B-2, 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 B-2 is very small in size. We made sure to trial and error fractions of a millimeter to finally get the B-2 to hit perfection.
The B-2 Bomber Nano Blade is the world's smallest and lightest tactical pocket knife ever to be created by mankind.

The following shows the steps of prototyping as well as process of how the B-2 Nano Blade came to life. During the design process, we had a few key elements we wanted to incorporate into the B-2 Nano Blade. The knife had to be small enough to carry discretely, however still big enough to be used as a functional knife. It also needs to be extremely durable. Consequently, we decided to use 440Carbon stainless steel because it is corrosion resistant as well as stronger than most standard 5Cr13MoV stainless steels.
The following picture shows a 2 dimentional drawing of the B-2 Nano Blade. It was our first drawing of the knife. It gives 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.
Once we had the 2D drawing, we were able to start making a visual product with depth. We then adjusted the thickness of the knife in the CAD rendering to create the perfect 3D model. We then use the 3D CAD model as a blueprint for the first tangible product.
Below is the first handmade prototype of the B-2 Nano Blade. We had used sheet aluminum to wire cut the first prototypes. As you can see in the pictures, we had cut out the holes for the screws as well as perforation in the blade using this method. This was not a functional prototype, as it was not safe enough to use. The sheet aluminum is soft and just an early design 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.
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. This gave us an understanding of first case usage, mobility, and design aesthetics. We also added more functionality to the blade by adding a hole for a keyring, as well as tilted the perforated slots in the blade to a 15 degree angle. This allowed material to slide off easier than standard verticle perforated holes. The second prototype does not have a blade edge or a serrated blade.
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.

Risks and challenges
If Bomber Survival Gear is successfully funded, we will have to make sure everything goes according to plan to meet the promised deadline. We have manufacturing, operations, and logistics set up and ready to go. The funding raised on Kickstarter will be used for production and manufacturing. Although we do not see any direct risks and challenges, there are always indirect or unseen tasks that may present itself during the process of productions. We hope to run everything as streamlined as possible and also ahead of schedule to make you the best damn everyday carry, ever.Learn about accountability on Kickstarter
