K390 Spyderco Endura factory vs first sharpening edge retention testing. This video shows why it's so important to sharpen your knife. Just one sharpening showed a gain over 200% in total cutting in a 1 inch section. Don't be afraid to go to the stones on a new knife, as long as I keep getting gains like this I'll continue to talk about how important sharpening is.
