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.
Telehex failed (I guess they’ve been trying to raise money on Kickstarter since at least 2015) because it offers no real advantage over a regular folding allen key with interchangeable heads. it’s only good for 3, 4, 5 & 6mm heads, so you’re paying an absurd amount of money for something that you could replace with one of these for a lot less money in the exact same form factor. plus, you’re introducing multiple possible points of failure; there’s no way a Telehex would survive as many uses as something significantly cheaper. same reason the universal socket didn’t stick around
