Since 1991, he's been crafting custom knives and contributing to the work of others through his expert blade grinding. That's right, this down-to-earth guy doesn't just create his own blades—he also grinds for other knife hotshots, including Pro-Tech Knives and a few others who would prefer to keep this well-kept secret under wraps. When he's not perfecting his own designs, he's contributing to the Knifemakers Guild and the Professional Knifemakers Association, ensuring the craft remains both high-quality and full of heart.
