Ergonomic Craft Blade

This art scalpel has a unique ergonomic design made to help reduce hand strain and feel good, any which way you hold it. An embedded magnet holds the blade in the handle and makes it safer to pick the blade up—this means you can store the knife on a metal surface, too. A latch locks the blade in place. Pick from a bocote hardwood, plywood, or paperstone handle.

Craft blade, art scalpel—whatever you call it, ErgoKiwi has redesigned the traditional pen knife to feel better when you’re at work. While studying architecture, Maker Sean Riley realized the knife he seemed to always have in his hand was causing cramps. He and classmate Cam Chateauneuf created more than 100 prototypes over two years trying to dial in on the perfect balance of form and function before landing on this unique design that felt perfectly balanced. ErgoKiwi stands out for its eye-catchingly different ergonomic handle, made from bocote hardwood, plywood, or paperstone. Once you hold it in your hand, you’ll feel the difference, too. You can hold it in any position that feels natural and it’ll help avoid strain by preventing hyperextension of the index finger. No tension or straining means you can work more comfortably and focus at the task (literally) at hand. Magnets embedded in the handle hold the blade in place and a latch locks it in. This is especially useful when you’re cutting thicker material. Even handier? The magnetic handle lets you secure the knife to metal surfaces when you’re not using it.
