As advertised - Spyderco Tri-Angle Sharpmaker Kit Knife Sharpening System

I am not a professional knife sharpener. This Sharpmaker does the job if you follow the instructions. I tried to do a quick sharpen with less passes on the stones than the suggested amount and did not see the full results until I did the recommended amount of passes. I own a few knives that are made of different steel and that also makes a difference on how many passes you need. I also purchased the ultra fine grit I don’t know if I needed them, but with how fast the sharpening goes I felt I needed to do more. My knives are as sharp if not sharper than when I first bought them.
