Take 2 handcuffs and 3 types of shims as shown in the above image.
Only 1 of the shims works on both of the handcuffs.
The other 2 shims are either too short or too wide to work on the handcuffs.

Developed by Karl OscarDelta the Uber Gulag Shim is precision engineered in the UK. The length, width and thickness ensure it will work with a wider selection of handcuffs that would otherwise resist or fail to shim with other commercially available shims.
These include American UZI, British TCH, Czech ALFAproj, Polish KEL-MET, Russian BRS-2, Russian CROT and Spanish ALYCON.
The Uber Gulag Shim is 304 Full Hard Stainless Steel that differs from other forms of 304 in that it has been hard cold rolled to its full hard condition. This increases its fatigue life. In its full hard condition, type 304 stainless steel has a tensile strength of 185,000 PSI minimum, and a minimum yield strength of 140,000 PSI. So unlike spring steel the Uber Shim will not easily snap when bent so it is possible to reshape and straighten.
Tip: Do not force the shim as you will bend it! Always start shimming where the ratchet arm enters, there should be a small gap, insert the tip of the shim and at the same time slightly push in the ratchet arm to assist (push assist). Only do this if the shim is moving between the ratchet and pawls (teeth) otherwise you risk over-tightening the handcuffs. In the event that shimming does not work it is possible that the handcuffs are either double-locked or have security features to prevent shimming.
