Hi everyone, I'm trying to find this (https://imgur.com/a/cJwU0Hv) exact item or an identical alternative. It's a very thick, uniform solid (or hollow?) stainless steel bar (looks around 12-16mm or thicker) with a smooth, anatomically rounded tip and no ball at the end.

The black grip on top looks like aftermarket tape or heat-shrink tubing.

Video reference: You can see the exact hook in action in this video
(from around minute 33:00 to 34:00).

Does anyone recognize it, or know an artisan/shop that sells hooks with this exact (or similar/bigger) heavy-gauge thickness?
Thanks in advance!
