Quick Answer
A blade finish that holds up best is a stonewashed or bead-blasted finish with a hardness of at least 58-60 HRC, as it provides both durability and rust resistance. This type of finish also tends to be more resistant to corrosion and wear. It's a suitable choice for a survival knife.
Blade Finish Comparison
When it comes to selecting a blade finish, there are several options available, each with its own strengths and weaknesses. A stonewashed finish is achieved by using a series of small stones to wear down the blade’s surface, creating a textured, matte appearance. This type of finish is highly resistant to corrosion and can withstand heavy use.
Durability and Hardness
A bead-blasted finish is another popular option, achieved by using a stream of glass beads to wear down the blade’s surface. This type of finish is also highly durable and resistant to corrosion, but it can be more prone to wear than a stonewashed finish. To ensure both durability and hardness, look for a blade with a minimum hardness of 58-60 HRC. This will provide the necessary strength and resistance to wear and corrosion.
Maintenance and Rust Resistance
While a stonewashed or bead-blasted finish provides excellent durability and rust resistance, regular maintenance is still essential to extend the life of your blade. Apply a thin layer of oil or wax to the blade to protect it from corrosion and wear, and clean it regularly to prevent the buildup of dirt and grime. This will help maintain the finish and ensure that your blade remains in optimal condition.
