ABUS is a well-known lock brand that makes high quality locks. The ABUS 82/63 Monobloc is a robust lock with a unique shape, made of brass.

This lock offers a nice challenge for lockpickers, but ABUS did fail in the lock’s security value, check out this video from Lockpicking Lawyer. So with the Peterson mini knife or Sparrows shank, you get this lock open in no time. Yet, as a lockpicker, you will get the orange band after opening this lock. So you may assume a good challenge (Band 3 out of 9).
