Quick Answer
Using a wet stone during wet weather conditions is generally safe, but it may lead to uneven sharpening and increased risk of blade rust. This is because water can seep into the stone's pores, affecting its sharpening performance. Proper care and maintenance can mitigate these risks.
Preparing the Stone and Blade
Before using a wet stone in wet weather, ensure it’s properly cleaned and dried. A damp stone is more effective than a dry one, but excess moisture can hinder sharpening. Apply a thin layer of sharpening oil to the stone to maintain its effectiveness and prevent rust. For a 6-inch stone, use 1-2 drops of oil per use.
Sharpening Techniques for Wet Conditions
When sharpening with a wet stone in wet weather, focus on shorter strokes and lighter pressure to avoid uneven sharpening and blade damage. Use a 20- to 30-degree angle for most knives, and a 15- to 20-degree angle for high-carbon steel blades. For a 30-second sharpening session, make 5-7 strokes on each side of the blade.
Maintaining the Stone and Blade
After sharpening, thoroughly clean and dry the stone, and store it in a dry, well-ventilated area. Apply a thin layer of oil to the stone’s surface to protect it from rust. Regularly inspect the blade for signs of rust or corrosion, and apply a rust-inhibiting coating as needed. For severe rust, use a rust remover and reapply a rust-inhibiting coating.
