This knife is handcrafted by the prestigious Vietnamese knife maker Bui Thanh Nam. He began studying heat treatment and high-end knife making in 2016, starting by designing and building two essential tools — a resistance furnace and a belt grinder — using only locally available materials. At the time, no company in Vietnam produced such equipment specifically for knife makers, and importing them was prohibitively expensive. Thanks to his hands-on experience and deep knowledge of cutting tools, Bui Thanh Nam won the Vietnam Bladesport Championship in 2018, was the runner-up in 2019, and still holds the national rope-cutting record: six clean cuts through 32mm ropes — a record that remains unbroken.

This knife is made òf Böhler N690 steel and are crafted by Vietnamese Bladesport Champion Bui Thanh Nam. We use liquid nitrogen (LN2) cryo-treatment on the blades to significantly enhance hardness, wear resistance, and overall performance.
