HAK Knives, short for HideAway Knives, are compact, fixed-blade tools known for their unique and functional design. Created for discreet and quick access, these knives are typically worn around the neck or looped over two fingers using a custom-fitted sheath. This setup allows users to perform tasks like carrying a flashlight or reloading a magazine while still keeping the knife securely in hand.

One user described their HAK knife as "very lightweight" with "amazing retention," highlighting the ability to use both hands freely without needing to holster or drop the knife. This functional innovation helped cement HideAway Knives as a respected and niche brand among knife users who value minimalism, quick access, and multitasking capability in real-world scenarios.
