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.
Imagine bearing against a stack of papers. It’s much more likely to deform than an equivalent size piece of wood.
Thinner parts make deformation and breaking more likely.
