Because kids these days love two things. 1) The Cleveland Spiders. 2) Pocket knives.
I'd like to imagine this is close enough to the version of a knife that Cy Young would have carried with him everywhere. Cutting up the baseball on the mound. Chopping down trees in two swift motions. Performing during the offseason at carnivals as a knifethrower. Wood whittling. You know, manly stuff.
