The Ontario Knife Company M9 Bayonet ON6143 is engineered for durability and field utility, combining a fixed blade platform with multifunction capability. Measuring 12.13 inches overall, it features a 7 inch blade constructed from 420 stainless steel with a non‑reflective black oxide finish to reduce glare and enhance corrosion resistance. The blade incorporates milled saw teeth along the spine, supporting light cutting and sawing tasks in field conditions. A black oxide coated steel guard and cap reinforce structural integrity while maintaining a consistent protective finish.

The handle is formed from thermoplastic nylon to provide a secure grip and long‑term durability under demanding use. The included thermoplastic scabbard integrates a wire cutting system and a universal military holster for adaptable carry and extended functionality. Designed to fit M16 rifle platforms, this bayonet supports both mounted and standalone use. The overall design prioritizes strength, versatility, and reliable performance in tactical, field, and utility applications.
