Purpose made decoding tool for many combination locks.
0.2m x 4mm steel shims for lock picking use. Approx 7cm in length.
Thin enough to fit where required, strong enough to apply the slight tension needed.
You need very minor pressure, just to feel what you are doing. Because these need to be thin enough to be useful, they will bend easily, be very gentle.
Can be bent into different shapes for other applications.
