One of the purported advantages of a wavy edged blade over a straight edged one is the inherently longer cutting edge of the wavy one for blades of the same overall length. The wavy blade may allow greater contact with the target and (supposedly) permit a deeper cut than a straight edge. Don't know if this theory holds any water, but I have heard it expressed on several occasions. There is some intuitive appeal to the argument. Perhaps some of our Filipino escrima experts can provide some definitive comments.
