BESH Wedge: n. a revolutionary knife grind composed of diagonally opposing bevels converging to create a third cutting edge.
Greatly improved tip strength providing improved pry-ability.
Increased wound trauma versus traditional dagger.
Ease of sharpening particularly in the field.
Robust enough for demands of warfare and domestic operations.
Creative potential of revolutionary and diverse Company designs utilizing the BESH Wedge.

Birth of the BESH Wedge
“BESH Wedge Technology was born when Beshara was working on a modern interpretation of a classic military dagger. Because grind symmetry is so important to the proper look of a dagger, it is not unusual for makers to grind the opposing (diagonally opposite) bevels to establish the initial look of the knife. They would then grind the remaining two opposing bevels to define the centerline and the final lines of the blade. In Beshara’s case, after grinding the first two bevels of the blade, he took a close look at the way the lines began to converge at the tip and realized that they began to shape a chisel edge almost like the sharpened tip of a flat screwdriver. Fascinated with the potential of this unique edge geometry, he ground the bevels deeper until he had a dagger with two diagonally opposite chisel-edged bevels. The two sharpened edges of these bevels met at the tip of the blade in a third edge that appeared to have substantially more strength and structure than a traditional dagger point. It also produced one of the most distinctive “looks” of any knife I’ve ever seen.”
“What he found was that his new design not only penetrated amazingly well, it eliminated the main shortcoming of traditional dagger designs: a fragile and easily broken point. With that, the XSF-1 was born.”
Results of testing
“….consistently penetrated better than single-edged tantos and traditional Bowie designs, but not as well as conventional double-edged daggers. Bear in mind, though, that the XSF-1 also does not suffer from the primary weakness of conventional daggers – a weak and easily broken point. When considered in this context, the extreme durability of the XSF-1’s point is much more important than the slightly better penetration offered by traditional daggers.”
“…during pressure cuts (cuts that start with the edge in contact with the target), the XSF-1 performed as well or better than most of the competition. I also found that its distinctive triple-edged tip produced spectacular cuts when employed with snap cuts and Bowie-style back cuts. During these movements, the square edges of the tip penetrated and cut in opposite directions, producing deep cuts with a minimum of force.”
“As a close-combat tool, it provides the capability of devastating snap and back cuts at long range, effective draw cuts at close-range, and incredible penetration at all ranges.”
“…one of the most unique designs to hit the knife world in a long time and represents an outstanding combination of innovative design, expert engineering, and high-quality execution.”
