A crooked nail: Concavus knows how to deal with this problem.
The certainty of hitting accurately is achieved with the circular concave form of the hammers head.
A badly angled hit will be compensated by the concave form on contact, offering a virtually orthogonal surface, which means the nail cannot be crookedly hit. This optimized hammer action makes Concavus particularly suited to physically challenged people or those with a bad motor function.
