Maintain the Sampson's serrated edge by rinsing off soil and debris after each hunt, drying the blade with a rag, and applying a light coat of machine oil or silicone spray to the steel surfaces before storing. The rust-resistant finish protects against surface corrosion, but prolonged exposure to moisture or acidic soil will eventually oxidize the metal if left uncleaned. The serrated teeth stay sharp through hundreds of digs without field sharpening, but if the edge dulls from repeated contact with rocks, use a small triangular file to touch up each serration individually, following the original bevel angle. Store the shovel in a dry location rather than leaving it in a damp truck bed or garage floor where condensation accelerates rust. The heat-treated edge is harder than the blade body, so avoid using the Sampson as a pry bar against large rocks or concrete, which can crack the heat-treat zone and void the warranty.
