Marc,
Are you talking about the same type splice Glenn St.Charles used in "Billets To Bow"? He divided the handle area of each billet down the center, then placed tick marks at the center of either end of those two divided sections. When you connect all the dots from corner to tick mark, back to corner, you end up with a "W" splice. You cut out of one, what you don't on the other. You can also introduce a little reflex into your stave at glue up!
