Multi Tool - This project was focused on creating a multifunction tool for a specific user group. It was sponsored by the Gerber knife company, and completed in collaboration with their industrial design department.
Persona - I created a persona to help guide and refine early research and ideation. This is a fictional composite based on research obtained primarily from law enforcement forums, as well as several phone interviews I conducted with police officers, both current and retired.
Use Context - I began thinking about user groups that have to respond quickly to emergency situations. Police officers are often first on the scene of an accident, and need to quickly and safely extract people from dangerous situations.
Existing Solutions - Research continued by analyzing current Gerber products, as well as their competitors. There are two major categories of rescue tools, compact simple tools with a focus on a strap cutter, and larger multi-function tools based on a folding blade. The top two products are current Gerber offerings. The next three are competitors products.
Sketches - Initial sketching focused on emphasizing the ability to cut straps, and a point for breaking glass. An area for improvement was the accessibility of the strap cutter.
Mid-Term Concept - This is one of the three concepts presented at the Gerber offices for a mid-project review. Based on feedback from this meeting, it was selected as the most promising.
Full Scale Models - A series of full scale models were made from styrene plastic. This sheet material approximated the construction method of the actual tool, stainless steel flat stock. Each model was tested for ergonomic fit, and several iterations were made.
Uses - A full scale model was made from stainless steel, aluminum, and FDM grip plates. These photos illustrate the essential functions of the final tool design. A strap cutter is always available, as well as a hardened point for breaking safety glass.
Uses - A full scale model was made from stainless steel, aluminum, and FDM grip plates. These photos illustrate the essential functions of the final tool design. The blade has a serration to cut quickly and a blunted end for safe use near a person. The blade is thicker than standard, to allow the tool to be used for prying without damage.
