Introduction
Ergonomic handle design can be the deciding factor between a forgettable kitchen tool and a beloved, high-margin product. For brands and makers ranging from heritage-inspired Masamune lines and established manufacturers like Tojiro to one-off boutique blades, successful commercialization requires alignment across design, prototyping, tooling, costing, manufacturing and quality assurance. This expanded guide dives deep into each phase, giving you practical models, checklists and tactics that are actionable in 2025.
