I am a knife advocate but probably from the master's view relatively a beginner. However, I do like to sharpen my knives. I have no confidence doing it freehand (from experience) so I am a real fan of the Lansky tools that eliminate figuring angles. Slow but sure. So now I stumble on the Work sharp power knife and tool sharpener. I follow up on you tube and think maybe I could get more done faster AND NOT RUIN MY KNIVES. I'm respectfully asking if following instruction this would be a low risk issue for me.
