Master a cheap kitchen knife first, how to pass the knife safely to another user and all the different grasping of a knife no shorter than 3 inches for the blade, (cutting part), then learn how to sharpen the knife properly. Then moved on to a mora knife, then after a few years,you can spend as much as you want for a good custom knife. But in my humble opinion, the best knife for a new rookie, would be the one you are holding in your hands. Also buy a good quality first aid box. You bound to cut yoursel, if you are thinking of playing with knives, happy mastering my friend.
Cheers the interceptor boy.
