Small but useful

This works fantastic for a standard hunting knife, where serration is generally not generally required. It probably won't work well if you have a very large knife since it is a bit smaller. It's a fact: deer hair kills sharpness. This tool helped me field dress two deer only hours apart with a quick sharpening in the woods. Without it, the 2nd one would have been difficult. It's compact, comes with a small chain to hang on a pack and it is very useful.

Great for emergency in the Bush

Works great for maintaining the edge on a knife that already has a decent edge. Works OK for sharpening fish hooks as well. Very compact and can be stored in any light weight hiking/camping kit.

Great way to keep a serrated knofe sharp

Stainless knives are great but keeping an edge really sharp was difficult until this ceramic device. Weighs little and easy to keep handy.

Good value

Good value for sharpening small blades, I use it regularly for several types of 3 inch blades. I was also able to use the grooves for serated edges.
