I’m not talking about a hex key that extends in length but one where it can collapse in on itself to increase in size.
I did some digging online but all I could find was a patent from a company called TeleHex but it kind of sounds like they came and went in the mid 2000s. They’re website doesn’t seem to exist.
I feel like it could save space in my pocket compared to a typical hex key set or a multibit.
I was hoping I could at least find a bootleg version on Ali Express.
I think this is a great idea! I guess strength might be the biggest issue? The metal would have to be layered really thin to fit all sizes, while being able to withstand strong rotational force. Although all the smaller sizes would fill the gap I’m not sure it would work. Making and testing this idea would be a good YouTube video, maybe send this as a suggestion to some engineering YouTubers?
