The Mac Coltellerie Apnea 9 Carbon Fiber Knife is the Ferrari of dive knives designed for professional and recreational diving. It is suitable for spearfishing, scuba diving, and freediving. The blade length is 7cm (2.75 inches), and the overall length is 18cm (7.08 inches), making it ideal as a lightweight and streamlined cutting device. 

The Apnea 9 Carbon Fiber is a single-piece stainless steel knife with an attractive red Teflon (PTFE) coating for superior protection against rust and erosion. It is double-sided, with one straight cutting edge and the other a serrated blade edge. The handle is sturdy and robust, made from stainless steel and double-coated with carbon fiber. The blade also features a shaft removal tool, and the base of the handle has a lanyard attachment loop.

Made in Italy, the Apnea 9 is designed and manufactured with a specific emphasis on high quality and practicality for hunting and diving. The comfortable handle, secure locking mechanism, and low-profile sheath make this knife a perfect companion for spearos and divers alike.
