The serrated edge on the Lesche Sampson is heat-treated and pre-sharpened from the factory, and it maintains cutting performance longer than smooth edges because the serrations concentrate force on smaller contact points. When the edge does dull after extensive use in rocky or abrasive soil, the serrations can be maintained with appropriate sharpening tools designed for serrated edges. The heat-treated aircraft-grade steel construction ensures the blade holds an edge well through demanding field conditions. Replacement is not necessary unless the blade suffers structural damage covered under the five-year warranty, making the Sampson a long-term investment for serious detectorists.
