This looks to have been mainstream knowledge for a while but it's the first I've seen of it.

"Proteus" metal;

Looks very resistant (I understand, there is a "guide plate" on top of the metal itself in this video).

Could be the answer to a lot of our problems gentlemen!

Well.. It will slow them down until they get a blowtorch at least...

Nothing new. ATM's (the big ones in a banks wall) are manufactured with a sand like substance sandwiched between the outer and inner steel casings. Problem is for a bike application is that it needs thickness to erode a drill or disc (as seen in the vid) and I'm not sure how you can achieve this in a useable bike product.
And what he's cutting inside the cover plate isn't metal, you can see the dust from the sand like substance blowing out.

Don't look at the Lockpicking Lawyer on youtube, puts you off swanky locks for life.... I found his gallium video very intersting, would be interested to see how this lock would cope.

Altor have realeased this lock for bicycles.





The size of the opening means it's not practical for motorbikes (or bicycles really).

They do admit you could angle grind it but it takes so long it would need spare angle grinder batteries & discs, so anyone trying to steal it is much more likely to give up or be noticed.

Waste of money.

All a tea leaf needs are a CO2 fire extinguisher and a lump hammer.

LPL is great fun to watch, not sure how practical a lot of his techniques are to apply to normal thieves.

Then again that can stand up to a grinder these days? If the lock is too tough they'll just cut whatever bit of bike it's attached to if they really want it.

Well the gallium did take hours to work but boy did it wreck that lock! His picks do not take long though and his approach to disklocks was disconcerting, who needs a grinder when you can bust it in seconds silently?

I’ve heard of a lot of ways of opening locks, but never with a fire extinguisher.

A mate used to keep his bike outside the front of his house with one of these unbreakable type chains that were popular at the time. Circa 15 years ago. Problem is he chained it to a wooden fence post.

No need to lug around a fire extinguisher when an upside down aerosol spray can will freeze anything

Don’t worry, I don’t think he will have up-skilled many would-be bike thiefs with that revelation... rolleyes

Make a thread once you’ve picked up your new bike then.

This knowledge has been around for years, my eldest (a copper) told me about it. He also told me the method for obliterating engine numbers if anyone wants to know.

I don't think I've spilt the beans to any would-be bike thieves. smile

It's really bulky and heavy also.

Wonder if they fill those voids with oil filled beads (or some lubricant to try to reduce the effectiveness of the cutting disc)?
