puck locks VS normal padlocks

[ARF-GEF]

So I've been wondering on my way to home today:

Puck shaped padlocks seem a lot more secure than normal padlock shaped padlocks. Still most of the high security padlocks (Grade 5 or 6 or the S&G wonders) are all made the traditional way.
I man with the puck, you can defend the weakest point, the shackle much better.
But since I'm not well versed in destructive entry I can only form an opinion but nothing based on experience.

So why is that pucks are not much more widespread(price?) and why is that the highest rated padlocks are not puck shaped?

Bonus question:
Is there any downside (either in security or in other way) of a removable shackle?


(PS.: I'm not sure where to post it, it might happen that to discuss it meaningfully it has to be moved to advanced(?) )

The round locks that Abus pioneered are quite inexpensive. I think their biggest downside is the cylinder seems restricted in size and perhaps complexity.

As far as destructive entry a cut off wheel in a cordless grinder pretty much negates any sort of padlock in seconds.

Maybe you haven't seen a 25/70 yet.
There's also the Abus Diskus Plus (disc detainer lock).

He is not referring to a discus lock, but a puck lock. I don't have a picture with me, but here are some Google pictures.

Used with the proper hardware, 'pucks' serve their purpose very well.
My van sleeps with them every night. 3 in total.
You can't cut those in seconds.....

Now those Allen-headed bolts on the other hand...

I guarantee that padlock on the van won't last 3 minutes. Yes it won't be from a grinder, but it can be drilled or picked.

I've opened quite a few of these for a local AC company. Of course it is better than the lock that comes on your van. You can only do so much.

Yes, I have seen those, but neither can take a full size cylinder like many normally configured locks can. Yes, the Diskus Plus is more complex and secure, but it still cannot be used in the same application that regular padlocks can. ie integrated into a MK system etc.

I think we need to steer away from DE. Don't want a legit question that others may be wondering about to get pushed over to advanced.

Just in case there are ANY questions about Discus vs Puck........

[Altashot]

Let's not force this thread to be locked...
I was only demonstrating to the OP a possible use of a puck lock, how and why it works...
Of course, like anything else, given enough time, it can be hacked...Even a bank vault can...

Thanks for the replies guys.

The round locks that Abus pioneered are quite inexpensive.

Maybe that's the reason. I never quite understood why Abus claims the discus to be such a fantastic construction. If we disregard the core (which can be put in a normal padlock too anyway) I see no big pro for the disc shape.
And abus claims: "Original Diskus-design: 360 degree protection"

and if we consider that too:

but it still cannot be used in the same application that regular padlocks can. ie integrated into a MK system etc.

So although Abus is totally in love with this discus design claiming it to be much better than the traditional design, but I don't really see that much difference.


Bembel:
I don't think that's the abus plus locking mechanism in the padlock you've shown.
This is the abus plus key:

Abus plus is an abloy style disc detainer, while the one you've shown looks like a lever lock with double-bitted key.
Nonetheless you are right that Abus plus is a very good lock.


But back to the original point:

On the other hand The puck lock looks like a big intimidating slab of metal. If the materials are good they should be extremely resistant to a grinder.
I still don't get why aren't the top security padlocks all puck-shaped.

(plus the bonus question remains unclaimed: Is there any downside (either in security or in other way) of a removable shackle? )
