“I wanted to create the perfect versatile blade for precisely marking wood, cutting foam core, doing papercraft, deburring parts, cutting vinyl stickers, trimming flash, whittling a spoon, and opening packaging.
Why another knife? After designing and fabricating thousands of objects across all manner of materials and processes, this knife became my passion project. I found X-acto blade quality poor - those little round pen-shaped handles always unscrew and get loose. Scalpels, while crazy sharp, are so flexible you often end up with wandering cuts in all but the most delicate tasks. And snap-off style blades, while great for heavy cutting like breaking down cardboard, don't have enough control for precision work.
When I discovered a niche line of British-made craft blades, I saw a path to perfection. These blades are 25% thicker than an X-acto and made by a scalpel manufacturer with fantastic edge quality. The key element keeping these blades from greatness was a lack of high-quality handle options. After dozens of prototype iterations and years of testing in my studio, I finally felt it was time to share.
The Studio Knife is CNC machined from billet 360 brass in Milpitas, California, and is hand assembled and tuned in my small workshop in Oakland, California, where it holds a place of honor on the top of my tool chest, always ready at arm's reach.” – Mitchell Heinrich, designer
