Dear Klaus,
: Explicitly I did *not* ask how to pick a lock.
I know you didn't but the secret doesn't have to be even how to pick a lock, just knowing what can be picked is also a secret.
As a locksmith myself successfully opened with my own tools and own method several particular high security locks. 7 years ago, as a trade school teacher,I lectured to other locksmiths on the subject and with weeks to months, the manufacturers had altered their locks.
this is why i don't want to public talk about what brands can be comprimised.
: Which leaves me wonder if there is an ultimate device not yet conquered.
There are but a cylinder itself doesn't have to be difficult. Consider the locksmith that has to open a cheap padlock, fixed to a gate when it's 6 foot off the ground and it's raining at night.
many handcuffs are designed to make it difficult just to get to the lock when applied the correct way.
: life. And improvements some manufacturers claim 'mushroom shaped pins'
: I remember were judged as slight complications only.
In some cases the mushroom or spool pin can assist the lock picker as each manufacturer use a size pin know to the locksmith and the postion of the pin can accuratly be judge by the mushroom section.
: They also explained some tools. I wondered what Yale locks are still good for after that.
"security" means "peace of mind" so if you are happy with your lock and feel safe it's fine, most people do. if you something to fear from anybody other than criminals, get really difficult locks.
: These less than preferred cylinders, if available with a cuff, that is what I would like
: to know. I have to admit that sometimes I really do not trust claims from manufacturers'
: side as they really can be quite at variance to my (theoretical) knowlegde about locks.
The cylinder whci i deem to be at the better end of the scale are Abloy ( pro or twin) Bramah, Vigie Pichard, certain Fichet.
next would be KABA. Bi Lock, AVA, DOM , Ingersol.
But each cylinder has both benefits and disadvantages, eg the KABA is fine unless you are likely to get dirt and dust in the cylinder.
: And when you say with sufficient time all is possible
: then the gifted magician still can pull off a successful escape.
Yes, especailly if the escape artist can examine the cuff prior to the escape attempt.
: And now imagine me entering the shop of a reputable locksmith and asking
: for a secure lock (well a good cuff in this case). Since the discovery of
: X-rays there is no real point in keeping the lock mechanism secret to the
: buyer, as I have to assume that a bad guy will have had a piercing look at
: it. I have to assume that bad guy has also trained himself on such locks.
your are right if what they want to gain is high enough to warrant the time and work.
I am not talk of petty theft and break and enter here.
: I could go into the nearest supermarket and have the salespersons there
: recommend me a lock. Chances are they would sell me the most shiny one :-((
The would and they would sell you what they stock in their shop, most would even know the better brands.
: But this reputable locksmith should be able to point me to the item
: in store which keeps (well educated and trained) bad guy busy
: for the longest time possible.
See above.
The better way to handle it is, purchase a high security cylinder which is not used in your counrty. both criminal and locksmiths alike ould find it difficult becasue they were not familar with that brand.
When a new locking device comes on the market, i study it before i would even attempt to pick it.
Knowledge is power and forewarned is forearmed .
