That would be an anti-bump pin, it is a D cut though I think I have seen references to a C cut before. It has been around for years.

so I went to a locksmith today to find some new locks, talked to a guy who worked in the business over 50 years. He insisted that these have NEVER been picked. also had no clue what a serrated pin was or that they existed. And the horror story: master lock was their high security padlock.

Bill and Teds Excellent Adventure!

That thing is a work of art!! Close tolerances make for precision products! Very nice!!!

Always interesting to watch you work, very methodical, and you explain what you are doing, and why, while you work. Certainly appreciate your efforts sir, thanks Bill!

Happy retirement Bill!! Thanks for the videos!

Very relaxing to watch.

Your lock has much more difficult bitting than the one I worked on, I had one with a very deep cut, but mine was on the last pin. I had purchased the SpooXe pick kit, and I was able to use only picks from that kit without modification to open the lock. If you examine the inner pins and the countermilling on the inside of the outer pins, you can see how it would be problematic if you overset the inner pins. Furthermore, if you look at the inner pin on the driver side, there's a groove that fits into the countermilling on the outer pin. I actually hadn't checked the bitting on the key before I sent that one to you, that one had the distinction of being the first lock I grabbed. I didn't know about the two part key pins. I hadn't disassembled my lock, I had assumed it was like the other "hard" Mul-T-Lock locks I had opened and left it at that. Thanks for making such a great video! You took far less time to open that lock type than I did, and the lock you have has much harder bitting. Your video is both entertaining and informative, congratulations on that open!

Lol, my favorite part was your "eleven minutes?!" at the end. Great content! Keep it up!

Thanks for keeping it fresh Bill. Always good to see new and old “alien technology”. For me,the more obscure the better. Sadly the internet’s various algorithms tends towards more popular things and ideas.

What a nice lock. When I saw the key I thought there'd be a magnetic component.

So calm and collected. Great pick on such a difficult opponent! Always love looking at multi lock cores

Well at least you got yours open, good picking Bill.

I admire your persistance!

Well done, I been picking one with no luck YET.

A nice gift, a bit tough with that bitting. Shame you couldn't use your fancy new toys on it. ✌😎

Nicely picked on that nice lock

Another excellent video. Good job

Cool lock looked like a tough pick, good job there!

Great job Bill.

Now that looked like a difficult pick. That kit from Multipick is awesome but this video shows it needs to add a few more picks to its arsenal. I hope they are watching.

What an interesting lock. Great pick for a video.

Hey Bill. Im looking at you pinning tray and how that ball bearing rolled out from chamber no 7.. if you cut the chambers 1mm deeper in the front gravity would work in your favor and the slight change and angle wouldn’t even be seen. Great video again btw. :)

it looks as if the #3 key pin is tapered as well which might have made it easier to over-set...

Kinda nice to see even bill gets picks stuck in locks ( like the rest of us😖)

Great video for new locksmiths like me 👍

Nice picking, Bill! 😎👍 I always love a Mul-T-Lock. Gave me a little pucker factor there with that Souber curved flag removal. I still dig the Souber picks, even next to that shiny roll of Multipick set. Easy ID, right?

Wow im never this early! Great job Bill! I love mtl but this one looks like something that would take me months to figure out!

nice core

Interesting!

I can't afford lock pick sets or lock picks in general but I find the hobby interesting and fun. I enjoy watching your videos and content 😊 keep up the good work!

I miss the challenge locks.

You. I learn things from you.

You have a D5 in the 4th chamber and A1 in the 5th, I thought there was a 2 MACS so the deepest outside pin should be a C. I could be wrong on this. It looks to be an authentic card so unless the factory messed up I don't know what to say. I'm a Mul-t lock dealer but only service one, once or twice a year. That " telescoping key is new to me as well as the C pin in the 3rd chamber. Could be a little different being a padlock cylinder.

Which pick from sparrows has close profile to the deforest diamond you use often, the offset hybrid diamond, the Attila, etc?

Nice video, nice picking, nice lock, thanks ! 👍

Really cool biding. Now multi pick just needs to make one of those pointy flags. Great work picking. Thanks for sharing. Hope you have a great rest of your day.

Wow

Those two circles nearer by side near the bow of the key, are they magnets? If not, what are they for?

😎Very very nice spp'd Bill great skills..Great lock Ted😎

The split pin is a antibump pin?

What kinda lock is pick, anti-bump proof? or how can you make one that is anti-bump, pick proof.

I thought this one had magnets,as it does not,what are those two circles in the bottom of the key?

0:47 these are the tools

I don’t understand why people continue to buy master or quickset when there’s these locks out there . It’s almost like Americans refuse to leave the lock stone age #mindblown🤯🤯

Nice job bill gose to prove lock pick makers arnt pickers. The most expencive tools that look pritty are not work tools lol. I prefer those solber picks.

I mean, I'd buy that for my home

Have you tried picking it with a dimple lock set? Because they seem like they would respond better to a set specifically built around being able to rotate better like the sparrows black flag set.

What are those two grey things on the key that look like magnets for?

The problem on this one? You didn't have any problem!

I always thought mul-t-locks were UNPICKABLE! GOOD JOB😀

how do you over come the magnetic pin mul t lock has

I have a lock cylinder from a 93 Buick roadmaster wanted to know if you would be interested in having it

Can someone give me Bill's contact info? I can't find it.

First Plus 14 😂

Why haven't you done challenge locks lately?

Hello. Can I order tools from you?

Interactive + open???

Welp, not so easy in the real world, eh?

OK, WHO was the 1 IDIOT that gave this a Thumbs Down?....Must be a Hater.....Lets see them do any better! This was an Awesome job on a rather difficult lock. Great job Bill!.....Luv your stuff!

So very far above my pay grade..

OK someone please tell me, is it FAULT set or FALSE set, I hear him say both words in the same video.
