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.
Interesting idea, but I think it would suffer from being too weak structurally to be of much use. Each consecutive size would have to slide in and out and that design would cause trouble with maintaining rigidity.
However, if you would find one let me know. I would likely buy it too.
