Yuri Kerzach had a switchblade that he kept on his person at all times. He carried it and used it in a variety of functions for most of the events at Pelvanida, Lab 101, and other Dragonstorm bases. He used it notably to stab Johnson Zenarchis to death.
In 2033, Alexandra Kerzach bestowed it to their son Malte on her deathbed. He used it in a number of nonlethal situations, such as cutting through wire fenses and turning screws. When he and Florence Brennan were attacked in the Nevada deserts, James Zanasiu Jr retrieved the knife from the spot Malte dropped it and stabbed several people with during in his attempts to rescue his friends. James later defeated Pomson in hand-to-hand combat with it and a stun mine.
