Anyway, what IS that thing you created? A space age screwdriver handle or something?
It's a new product called "TraceMate". It's for tying heavy monofilament Nylon fishing line to hooks & swivels for sea fishing. It was developed by a guy I work with. He's been using something he just knocked up out of some scrap Ali for years but then decided that he could market it. We talked about how to make it more suitable for mass marketing and together we came up with what you see. I did all the CAD work and arranged for the Z-Corp sample but it's his baby and based on his original design. We've had Aluminium extruded to the correct profile and do all the machining at work. I'm not making anything out of it myself but hopefully if it takes off he can make something from it. There's a review of it
here. Usually they're Anodised Red, the one on my photo is Yellow because we had some powder coated as a trial.
