I know there are lots of ways to cut them, this is what works for me: Take a piece of band saw blade about 3” long (¼” X 14 TPI works good) put a slim handle on it maybe a piece of 3/8 RR. Taper the back edge of the blade down to a point so you end up with something that looks like an isosceles triangle with teeth.
Rough the engrailed or step down as you would on any horn, NO fish mouth yet. Draw the corners of the fish mouth in and blend them into the step. Score the line with a sharp knife.. Then take your new saw and saw the line to depth, the blade is thin enough that it will allow you to make the curve, just do it a little at a time. Use files and a long skew chisel to clean things up and smooth out the curve. If you score the corners with a sharp knife MANY time on both sides the skew can be ued to pop the little triangle out. Kind of a four step process, work the neck down to the step, one side of the mouth, then the other, clean up. The teeth, for lack of a better word can be cut with the tool of choice.
I hope this is understandable.
