indra / Cranked wrench key

Once a screw does not release by the first try,
lots of handyman try to figure out the right direction by turning harder and harder in both directions.
The consequences: broken threat, broken screw head, damaged tool.
The solution: “indra“, the innovative cranked wrench key.
“indra“ is handled intuitively. The spiral-shaped torsion of its steel body shows the direction of the threat of a regular screw. As a result, the user starts turning the key unconciously to the right direction.
Even if the user is not able to see “indra“, its palpable torsion helps him turning the key and the screw to the right direction.
Innovative and easy.
