For many operations the least expensive tool to use will be the one which can offer the most resets, thereby providing as many as four top quality tools for the initial price plus the cost of three resets. To achieve the maximum level of resets, the tool must be carefully turned in its holder during use and returned for reset before the point is over-used.
