Yesssss! I am now the proud owner of a knife that looks like a watermelon and is designed to...cut watermelon!
That is all.
(Addendum: I figure I should share details because I know you will want a watermelon knife of your own. It's Kuhn Rikon and has a matching red sheath. This knife will make you smile every time you see it and it cuts watermelon better than anything I've tried. It's perfect for those moments when you really need lots watermelon IMMEDIATELY, with no futzing about looking for the right knife or sawing through the skin with a dull blade. If you like watermelon, you don't want to wait for it, am I right?)
