My vises are made by Panavise, a U.S. Company.  The one with the wide jaws is the model 350.  The smaller one is the model 301. Both have the 312 Base mount – www.panavise.com

  1. would a way for manufacturers to combat this exploit be to make that silver-ish "lock disc" thing long enough (probably 3cm) to the point where leverage on it wouldn't be able to pop it out? as the bottom of it would bind against the cylinder wall

  2. Having lived in China for a little while, I concur with ScoobTEQ. I'd guess that Hermex's factory (or factory contractor) first manufactured the lock design, or at least first contracted the design in China, (like San Ren Mu and Byrd/Spyderco knives).

  3. I have seen a lot of locks like this and some of them you can pop with a screw driver. some are harder but I fount with a small pocket sized 1300c torch you can heat the thing up then pop it quickly. I have also recently seed a video wear a guy hade a $100 high secerity lock that the mfr clamed could was un pickable and un breakable and work take 10min to cut with a cutting torch and well he hit it with a hammer as it was hanging and it poped right open. I cant rember his name it was something with locktester secerity

  4. Looks like the body started to give up the ghost at 5:05 when you spun it around. Is that a vacuum base vise? Moisten 1/4" of the edge of the diaphragm before mounting. If the surface is smooth enough, it will not move. Trick works also on windshield mounted Nav systems.

  5. Knowing how manufacturing in China works, I suspect that the factory that created the mechanism in the Hermex was the original creater this design/manufacturing process, and all of the other disc detainer locks are knock-offs of this design. Interesting that this one appeared to be better machined and the detainer was heaver.

    Good stuff, thanks for sacrificing your self for science 😉
