2. Key Features
2.1 Black Titanium-Coated Blade with Stone-Washed Finish
The blade is forged with a 5.5mm thick spine and features a stone-washed black titanium coating. This coating reduces glare, resists rust, and the textured finish minimizes handling fatigue. The 5.5mm thickness balances strength and weight, making it suitable for heavy-duty cutting, chopping, and wood processing.

2.2 Curved Spine and Handle Design
The continuous inward curvature from the spine to the handle is designed to conform to the palm's structure, reducing hand fatigue during prolonged use. This design focuses force on the blade edge, enhancing cutting efficiency and improving blade direction control during swings. It also increases the blade's strength by widening its narrowest point to absorb and cushion impacts.

2.3 Full Tang Blade & Clip Point Blade
The full tang design ensures the blade and handle are seamlessly connected, providing maximum strength for chopping and detailed work. The clip point blade concentrates force at its sharp tip, enhancing piercing efficiency for tasks such as penetrating hides or opening tough packaging. The curved belly of the blade offers a longer cutting arc, making it suitable for various cutting applications.
