Presentations for the Dutch Open 2007

As organizers of the Dutch Open we feel the pressure building up. Will everything work out? Can we satisfy the people and offer them something nice? Looking at the presentations we have to offer I think we can ….

Kick off

Friday around 20:30 Paul Crouwel will kick off the Dutch Open with his presentation: High security safe opening

As regular visitors of this blog know, Paul Crouwel is a highly skilled safe technician that opened many high security safes. During this presentation he will try to open at least one high security safe. Before trying to open it he will reveal his plan of attack and then execute it. When the safe is open it is time to party ๐Ÿ˜‰

And there is more Paul Crouwel will do at the Open:

Saturday 15:30-17:00 Paul Crouwel on combination lock manipulation
(second track)

This will be an intimate class with room for only ten attendants. Paul will explain the basics behind safe combination lock manipulation and hand out ten Sargent&greenleaf 6730’s combination locks for some hands on training. At the end of the Dutch Open these locks can be purchased by the students for a very reasonable fee. This presentation will also be held on Sunday after the lockpick championships (around 15:00).

Saturday 10:00-15:00 Peter Field, lock Pathologist (Lunch 12:00-13:00)

Peter Field has an extraordinary way of looking at locks. Like a pathologist, he cuts locks in many thin slices and captures the result with high quality photography. This unique methods of creating a cutaway view is world renowned. His lectures have been attended by locksmiths, security personnel, lock company engineers and Patent Office Examiners from many countries. And now we are proud to welcome him to Sneek.

Peter Field, Lock Pathologist

He will set a Dutch Open record by giving a 4 hour(!) presentation about many of the different elements of high security cylinder lock design. Combining his unique cut-away imagery with illustrations from old patents, he will explain how engineers classify the cylinder elements, modify them, develop new ones, and re-combine them all to invent new products for the constantly evolving security market. You will leave this presentation with an outline and a clear understanding of the design constraints and functions of most of the various elements you may find in any lock cylinder.

Even if you know a lot about cylinders, or you are just starting to expand your knowledge into the field of mechanical locks you will not be disappointed with this presentation. If you had to choose only one class about mechanical cylinders to attend this year, this is the one to choose.

About Peter Field: he started locksmithing in 1960, and in 1978 was asked to join Medeco Security Locks, where he is now Director of Research. He has over 15 US Patents pertaining to high security locks, with several more patents pending.


Saturday 15:30-17:00 Impressioning By Oliver Diederichsen and Barry Wels.
(track one)

Impressioning is the fine art of opening a lock by filing a key from a blank. It is an ancient technique that still works on an amazing number of (high security) locks. Besides an old-skool locksmith skill it is a technique still in use today by intelligence agencies worldwide for their blackbag operational need.

Image from the book 'Impressioning' by Oliver Diederichsen

Oliver Diederichsen wrote the leading book about impressioning locks (also available in English now) and teaches impressioning courses all over the world. And he introduced many locksport enthusiasts to this fine art. Amongst them Toool president Barry Wels, who over the last months successfully opened at least fifty different brands of locks trough impressioning. As the blank key is the most important weapon of the impressioning artist, Barry invested a great deal of time in finding the correct blanks for European and US locks. A search that is still going on today.

This hands-on workshop will teach and tell you everything we know about impressioning. From the very basics to open five pin tumbler locks till the more sophisticated fifteen pin dimple locks, and more.

Multiple tracks

The good news about the new location in Sneek is there are three conference rooms. This gives us room to experiment with something new. The other two conference rooms will be available for people to give small presentations. Just claim a slot on the chart (30 or 60 minute slots available) and give your presentation to whoever is interested. It is not necessary to send us an e-mail in advance, but we would appreciate it a lot if you did. Even before announcing this we had the following presentations offered:

Decoding Abus Plus/Granit locks by Jaakko Fagerlund

What could this design flaw be .....

This presentation covers one of the most humorous lock decoding techniques I have seen in a long time. Jaakko will describe the major design flaw in the Abus plus style disc lock and explain the basics of the exploit and how it can be done out in the field. And briefly talk about the reaction from Abus.

Lever locks by Nigel Tolley

Lever locks were, until recently, found on the majority of domestic doors in the UK, and are still found on most commercial premises. They are available in everything from a one lever privacy lock, right the way up to the 7 lever Chubb 110, and, of course, with even higher lever counts in the locks found on safes world-wide.

Nigel Tolley, a UK locksmith, will be giving us a brief tour through these locks, concentrating on those commonly found on doors rather than safes, and their evolution over the years, as well as touching briefly on methods for overcoming them, plus a look at some of the dedicated tools for the harder ones. Some locks will be available for swap and demonstration.”

‘Back Dialing’ by Mike van der Stelt

Mike will talk about a technique to easily read the combination of a safe lock if you find a way to view the change key hole.

Congratulations if you have read all the way till the end!

More news on the exact schedule and what locks we will use for the championships in the days to come …

    MEGA POST!!! nice, I hope you guy record some footage so we can see some of the new tools/techniques

  2. Lockpicker says:

    Will those presentations be published on toool or Youtube? I would love to see them live, but I dont affore to travel to NL from Sweden.

  3. Barry says:

    Lockpicker: as said before on this site … these presentations are unfortunately invitation only. More info on the publicly available championships in the days to come. The golden rule is that everyone who wants to attend needs to register, even for the public part! And I am not sure what will be available on video….

  4. What a lovely warm feeling I have when I see my name mentioned in here ๐Ÿ™‚

    I hope I don’t stutter for the 30 minutes ๐Ÿ˜‰

    In what kind of price range are those S&G 6730 locks, as I would be interested in them? I’m thinking of bringing some Abloys hopefully with me, probably as cutaways and some others too if I can’t get them sold.

  5. Barry says:

    Jaakko: I am not sure, probably around 50 to 70 euro, mounted on a nice stand. But in a week or so I will know more about it …

  6. mercurial says:

    Wow! This is obviously shaping up to be yet another information-packed, fascinating Dutch Open!

    One query – I’m no expert on lever locks by any means, but I believe the Chubb 110 contains 5 levers, not 7 as stated in the article?

    Hopefully I have the opportunity to attend the Dutch Open in the next few years.


  7. TOWCH says:

    Congratulations Jaakko!

  8. Thank you TOWCH ๐Ÿ™‚

    And I’m with mercurial, the Chubb 110 is a 5 lever.

  9. NKT says:

    Oops, that will teach me to knock out a decription in 5 minutes! Yes, the 110 is a 5 lever lock. It should read “the 7 lever Chubb 3G117”. ๐Ÿ™‚

  10. shane says:


    Do you have any details and info for me on the Dutch open? I might be interested in attending.



  11. mh says:

    “Just claim a slot on the chart (30 or 60 minute slots available) and give your presentation to whoever is interested.”

    I’m not sure if that’s suitable for / worth a presentation, but I’ll bring along some locks from my collection, some more complicated locks and some cutaways (and some which are both :-). After all, not all of you guys might have seen a ‘live’ Fichet 787 or Monopole, or a Rielda lock, so I hope you’ll like it.
    Again, probably not worth a 30 min presentation, but you can have a look during the breaks…

    And there will be some ABUS Plus locks for Jaakko to practice his invention ๐Ÿ™‚
