John Marconi, Marconi Blades: The Knife Junkie Podcast (Episode 650)

Professional chef meets custom knifemaker in this week\'s episode of The Knife Junkie Podcast. Host Bob DeMarco sits down with John Marconi of Marconi Blades to discuss how his 18 years in restaurant kitchens shaped his approach to making purpose-driven, everyday-carry fixed blades. John brings a unique perspective to knifemaking, combining the precision required in fine dining with the demands of defensive blade design.

John started as a dishwasher at age 16 and worked his way up through professional kitchens, eventually becoming an executive chef. His experience in fine dining taught him exactly what a knife should do, from the geometry of a convex grind to the importance of handle ergonomics.

These lessons now inform his work at Marconi Blades, where he creates fixed-blade knives using CPM MagnaCut steel and offers ambidextrous sheath options. The conversation covers his flagship Tuilm model, influences from makers like Frank Windle Jr. (Northman Blades) and Brian Schultz, and why he believes functional tools should also be art pieces.

The episode also talks about the practical side of making and using knives. John shares his preferences for kitchen knives, including his decade-plus relationship with a Zwilling Bob Kramer blade and custom pieces from makers like Greetham Knife Co. Bob and John discuss steel choices, grind geometry, and the future of Marconi Blades, including upcoming collaborations and new models in development.

Listen as John explains how the chaos of restaurant kitchens prepared him for the controlled precision of knifemaking. Hear about his brother\'s parallel journey into knife work and what it takes to balance a full-time chef career with a growing custom blade business.

This episode offers insights for anyone interested in fixed blade design, defensive knives, or the intersection of different blade disciplines.
