It will absolutely put a decent edge on a knife with zero skill on your part. A few strokes and bingo. The downside, as Kerry so adroitly pointed out, is that it is a little tough on your knife.

It is certainly a consideration if you want a fast, easy and safe method for putting an edge on a knife that will be fully capable of cleaning even tough big fish (large thick scales).
