Care and maintenance
RRK knives are built for hard use in the field, shop, kitchen, and everyday carry. To keep your knife performing at its best, proper care and routine maintenance are recommended.
After each use, hand wash the knife with soap and warm water, then dry it completely. Do NOT place your knife in the dishwasher. Apply a light coat of food-safe mineral oil or knife-specific blade oil after cleaning to help protect the blade and maintain the finish, especially for knives used in the kitchen or around moisture and acidic foods.
Avoid prolonged exposure to moisture, saltwater, blood, or acidic materials, and never leave the knife stored wet or dirty. For long-term storage, keep the knife in a cool, dry location and avoid storing it inside a leather sheath for extended periods.
To maintain the edge, use a leather strop or carbide sharpener between full sharpenings. Avoid power grinders or excessive heat during sharpening, as overheating can damage the blade’s heat treatment and edge retention.
Rapid River Knifeworks offers free sharpening and polishing for the life of every RRK knife. Simply ship the knife in and the team will restore the factory edge and finish. Customer is responsible for return shipping.
Shipping and delivery
