Explosion Bonded Titanium and CPM S30V stainless steel (XBOND): The MA-4/II XBOND 5.25” Tactical Knife is the ultimate tactical edged weapon and is an ideal knife for both the collector and the professional.

Only 25 knives were made of the Explosion Bonded Titanium and CPM 230V. These 25 knives represent the first and only time stainless steel was Explosion Bonded with titanium for any application, not just knives - this is a proprietary aerospace manufacturing process - a true Space Age material.

"The explosion bonding manufacturing process permanently fuses otherwise incompatible metals at the molecular level." - PA&E

Titanium and S30V stainless steel is formed into a true metallurgical bond as a result of a powerful explosive detonation, creating robust, yet lightweight construction.

Shown in the first photo (left) is the raw, and very hot, MA-4/II blade material shortly after the bonding detonation. The first MA-4/II prototype knives were made from this particular piece of material in April - May 2007. The explosives are place directly on top of the two pieces of material. The blast marks are visible and the material is warped from the extreme force and heat of the explosion.

In the second photo (right), a magnified cross-section view of a different piece of bonded material shows the layers of different metals now one.
