A Benz knife is a knife made by Benny Delon after every time he committed murder. There are 288 Benz knives in total, each of which is engraved with a number and incredibly sharp, enough to cut Silva Zoldyck's skin. Gon and Killua discovered that these knives can be found by using Gyo to detect the aura Benny Delon unintentionally left on them. At the present time the prices of the Benz knives vary depending on the incised numbers, but each of them can be sold for at least 5 million Jenny.
