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. Nou, iemand die een scooter wil stelen, moet wel héél snel zijn, om dat slot open te maken. Ik heb 'm ook, gekocht op de vrijmarkt, voor……VIER euro!!

  2. Took a wee while compared to other locks I've seen being picked here on youtube. Glad my garage has one of these locks on it!

  3. If the body seems not to be fully hardened, makes you wonder about the shackle hardness… I used to work in a shop that had a Rockwell hardness tester, and that was sort of a neat thing to be able to know, though it might not give an accurate representation past surface hardness, so you still would not know if it was fully hardened or case hardened.

  4. Based on the cost of a new Kwikset and compared to what your hourly rate should be, it is almost always more cost effective to brute force a Kwikset and replace it with a new one than it is to pick it. Besides, when you pick a customer;s lock it is usually because they either damaged the lock or they lost the key. Use the tool, screw on a brand new lock and be done with it.

  5. Kwikset's "smart key" is not so smart. You can pick it easily like most Kwiksets. Also, it looks like Kwikset has discontinued (or will soon discontinue) that line because there is a bypass tool that opens the lock. Once opened, the opening is not detectable and can be relocked. Only the re-key function is damaged (sometimes) using the tool (See MBA Inc's site). There is nothing special about the pins themselves. This was a test, right?…

  6. I'm partial to Sparrows for my rakes and Peterson International for my hooks. That's pretty much what I use for pin tumblers. For dimples I use home made picks and Souber Tools' kit.

    I'm unsure which Smart key you mean – there are several manufacturers that use that term. The most common is Kwikset – is that the one you mean?

  7. Thanks for responding so quickly. I'm a Locksmith in Los Angeles, I've only been at it for a little over a year. I'm a big fan of your posts. What do hour find to be the best pick set. And have you ever been able to pick the smart key? If so how?

  8. Correct. It just leaves more room to work in the keyway. It is also more central and makes it a little easier to feel and tension the core. Either way will work though, so just use your personal favorite.

  9. Hi I was wondering what the reason is for using too of the key way tension vs bottom? Is it just a matter of freedom of movement with the pick?
