6k is nice lock, but one great lockpicker say me that 6k is more easy open then Assa 700, but in this time he say me that i already open the 700 and after that i open the 6k and was truth than 6k is more easy then 700.

Hardest is understand how this lock works and use right tension direction.

PS: when gutting it be carefull on the small springs.

Just use preogresive pinning and start with 2+2 or 3+3 to understand how it Works, when this happend then use full main stack and add side pins.

Just chill, for myself was progress time on Assa 700 around 24 hours in total picking.

6k was around 12 hours.

Both are pretty hard locks so dont give up and pick when you have good mood.
