(919) WCP’s “The Big Easy” Challenge


LockLab is Fan funded!  Help pay for stuff to review, break and talk trash about, and maybe even give away when we’re done.  Join the Tribe!

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. Just found your YouTube videos and I love them! Trading my knitting needles in for picks after opening my first lock ( okay, it was a Master lock so not big a deal). Hope to learn more.

  2. I think that raking and ‘Bumping’ are both kinetic attacks that act more like a real key (sometimes) than a spp method. A key raises all of the pins to the shear line without any rotational tension on the core, and then tension (torque) is applied when they are all at the shear line and the lock opens. Pins to the shear line and then torque on the core versus pins to the shear line with torque on the core. Not a subtle difference. I appreciate your comment about using light tension.

  3. As Bill has said in the past, “If one method does not work, try another method”, and raking was definitely a better option with that lock. I’ll even mix it up, and rake to a false set, then SPP, or SPP to the point I’,m stymied and then rake, Whatever opens the lock, aside from a key, and I am neither above or below impressioning keys too. If that fails go to destructive means, unless you need egress without any evidence of tampering.
