My CAD course required a team project where we had to present an idea then go out and design/model the proposed item. We chose to redesign the pocket knife, where you can readily interchange the components. The user would be able to choose three tools from a huge amount of products with which they can use to construct their pocket utility tool.
A simple allen wrench in the tool's grip is used to tighten/loosen a shoulder bolt which acts as an axle for the tools to rotate on. The pocket utility tool utilizes a tried and true "slip-joint" locking mechanism to hold each tool in place when it is opened. The handle itself is constructed from thick stainless steel, and the orange grips would be made out of zytel, a hardy plastic material.
This tool was built around a few key points. We wanted it to be rugged, functional, easy to use, and versatile. By being able to switch out tools, this pocket-sized (3" by 1" by .75") tool can serve any function the user desires.
I'd like to thank Robert Frazee and Sean Montgomery for being such hardworking team-mates. We spent an entire "marathon-monday" 3 day weekend on this project, and we are very satisfied with our creation. Also thank you Marc Beneck for rendering such beautiful visuals using Keyshot.
