To find the angle of your edge place blade on your finger nail and move back and forth while raising the angle, when blade grips nail take note of angle. The best advise I can give is to consult your local butcher. 2 min with butcher and you will be half way there. I learnt from my father (butcher) when I was a kid. It's very easy if you are shown the correct technique . Best of luck
