Spyderco C204MF Tri Angle Sharpmaker Set Knife Sharpener
[C204MF]

I have used many sharpening tools including stones. This is undoubtably the easiest and fastest system to master. If you're not a knife sharpening pro, or want a system that's fast and simple, this will turn out hair popping results with a very low learning curve. Great video. Definitely a great system.
