The Knifemaker

Steve Dumchus has been making knives in New Jersey for over a decade. What started as a passion for craft and precision evolved into a body of work spanning custom one-offs, competition pieces, and collaborations with some of the best machinists in the country.


Every knife Steve makes goes through his hands from start to finish. American steel. American craftsmanship. Built to be used, and built to last.
