Note on use:

Thanks to its length, the VATTO15 develops particularly high leverage. To avoid damage to the thread, Runwell recommends:

• For M10 nuts : max. 13–20 kg tensile force
  Always work carefully – overtightening can damage the thread.

A tool with character:

The name VATTO (Japanese: 抜刀 – "drawing the sword") is a homage to Japanese swordsmanship, where the outcome of a duel is almost decided upon drawing the blade. Likewise, the removal of this tool from the toolbox is said to determine quality and professionalism. A symbol of precision, control, and skill.
