Mini Sharp，FINE，DMT 鑽石折疊磨刀器

Used the fine side after my coarse stone and the edge came out noticeably cleaner, shaving sharp off a 600 mesh. Fits in my pocket at the campsite and weighs basically nothing.

The keychain attachment is what sold me—it lives on my pack and I forget it’s there until I need it. The 600 mesh surface puts a real mirror finish on my knife edge in a couple of passes, and it takes up almost no room in my pocket.

Went camping last weekend and used it to touch up my knife after a morning of food prep—the 600 mesh diamond surface brought back that fine edge in maybe a minute. The folding design with the keychain loop made it disappear into my pocket until I needed it, which is exactly what I wanted.
