I’m gettin’ one these babies for sure.
Texas Aggies have been doing that for years, using our Senior Rings for that purpose. Kinda of a skills test, but does get a bit rough on thr gold after a while.
But seriously, unless you drink an import or microbrew that doesn’t have a twist off cap, as most do now, you don’t need a device like that. People still for some reason seem amazed when you can grab a beer botle with a twist cap, and open it without having to use a towel to keep from hurting yout hands or a bottle opener.
Its called grip strength folks.
But after sitting here for a minute and looking at that device again, as a former bartender I must say if it worked, it would save a hell of a lot of time over a speed blade.
