If you are trained properly by a master Samuri you can cut melons in one motion.
Good suggestion......but I have yet to be attacked by even one melon....it's usually the other way around. I'll carry melon pepper spray, just in case. <img src="/forums/images/graemlins/grin.gif" alt="" /> <img src="/forums/images/graemlins/grin.gif" alt="" />
A thought occurred to me (yes, sometimes thoughts emerge from all the voices in my head.... <img src="/forums/images/graemlins/cool.gif" alt="" />).
Take a Sawzall...reciprocating saw...blade, like this: http://www.amazon.com/gp/product/images/...13&s=hi
And grind a knife edge on the back side.
I made a file handle to hold one of these blades, which weighs practically nothing when done. As a knife, these blades aren't "hard" and wouldn't pry well, but otherwise you'd get one killer saw with a knife on the other side. Dual purpose. Just an idea I might try since I have lots of recip. blades laying around.
