Aircrew Survival Egress Knife

[1][2] The ASEK replaced the "knife, hunting, survival pilots", which had a number of problems with the leather sheath and handle, the sharpening stone, and corrosion resistance.

Packaged in the sheath are a special tool for cutting seat belts and a diamond impregnated sharpening disk.

It includes a crushed diamond disk sharpener and a separate blade for cutting through seatbelt webbing.

[4] In May 2005, Gerber Legendary Blades introduced its own ASEK-compliant knife (available commercially under the name LMF II) to the military for evaluation.

The Gerber ASEK met all requirements, and outperformed the Ontario model in the area of electrical insulation.
