Buy this when bottom-of-keyway tension is crowding the lock
A better-fitting TOK wrench lets the pick move more freely while the plug still talks back. The extra shapes and reach give you more ways to find that fit.
Eight options
Different shapes and widths help with awkward keyways.
Extended reach
Longer tools give more hand room on cramped locks.
Dedicated case
Keeps small tension tools together on the bench.

Fit the wrench before choosing the pick
Start with the wrench that sits securely at the top of the keyway without wobble. Use light pressure and change wrench shape before forcing a crowded setup.
- Try TOK tension when BOK tension blocks pick space.
- Use lighter pressure than a rigid wrench tempts you to use.
- Keep the set organised in the included case.
