Can any one tell me the bevel used in Shun knives? I thought they were 50/50. Some one in another forum told me they were 90/10. Then I saw 80/20. Which is it? I hope it is 50/50 which I assume is easier for a novice to learn to sharpen. Never thought of using stones. But now that I'm thinking of buying some JP knives... (not expensive...$50-200 range...per knife...some one recommended Tojiro Shirogami...white #2 steel knives for around $60 US each)...I figure i might start learning... What if you have a 70/30 edge on a JP knife? What does that mean? Just that there is more cutting surface on one side of the cutting edge? Does such a knife still have 2 15 degree angles? (doesn't seem so) And briefly how does one sharpen a knife without a 50/50 bevel?
