Out of Ten

I recently took the 4-in-1 Portable Tungsten and Diamond Field Knife Sharpener out on a multi-day trek to see if it could actually handle dull knives in the wild. Testing it on both a standard pocket knife and a few blunt fishing hooks, I found that having four distinct sharpening surfaces makes a noticeable difference in edge recovery.
