Interest in custom security chain?

[El Feo]

The 2 most vulnerable parts of the lock are the shackle and the lock cylinder.

For the shackle, best way to go is to choose a lock where the shackle is not exposed, or depending on latching requirements, as least exposed as possible. Then make sure the lock cylinder is drill/pick resistant.

The reason i use mul-t-lock for everything is their really unique pinning system. Damn near impossible to pick (last one took me 8 hours to drill through) , bad ass key, and they come with a key card thats registered in a database to your name. your the only one authorized to receive a duplicate key or re-key it.

you will instantly know the quality when you hold one in your hand.
gives me a boner every time.

I use a few different setups. But, I was just curious which is resistant: an 18mm exposed shackle (Krypto) or a 10mm protected shackle (Squire) which is further obscured by the chain.

I considered a Mul-T-lock but it seemed better matched for larger chains. And, a bargain at $420

I guess nothing will withstand Longfellow Lou and his plasma cutter or a dominating Derrick with an angle grinder.
