Hi Attie
It's a art forum and it takes years to get it down right, you can get many books that will show you how and buy many tools to do it with but again no easy way to get it down, it just takes time, the best way I have found is to sharpen the tool and then test it, if your happy with the cut use the tool if not, sharping it again, a pro. can make it look easy but it's not it's like when you see someone painting they make it look easy but it took them many years to get it right..
