Tree wedges are used to hold open tree cuts to prevent any blade pinching; something that can be frustrating and potentially dangerous to arborists. Working closely with Notch, we focused on optimising harness space for arborists carrying multiple wedges. Together we developed the Notch Dual Wedge, a patented solution that combines two wedges into one, designed to work with varying kerf widths. This reduces clutter while allowing for customisability, helping arborists stay organised and efficient in the field.

With an aim to reduce harness clutter, and through various rounds of concept development and user interviews,we soon landed on a (now patented) interlocking system where two wedge halves twist together precisely and firmly. This solution combines two wedges into one and offers multiple wedge heights to choose from depending on blade kerf widths
We used rapid 3D printing and iterative testing to perfect the wedge’s unique interlock and hinge. This hands-on process let us refine every detail before committing to tooling, ensuring clean separation, a tight fit, and long-term reliability right from the go.
Lightweight and easy to carry, the Dual Wedge fits seamlessly into any climbing setup. Its hinged lock keeps it secure when joined yet allows fast separation when needed. Designed for durability and ease, it’s a tool that keeps up without getting in the way.
