Demigods at Camp Half-Blood are trained in Greek weaponry because the Greek gods have influence over those weapons. I mean sure a demigod could use a katana or a shotgun, but it wouldn't feel as natural as a Greek sword or bow. Same applies to Camp Jupiter. Plus I'm sure no one would want to use a scythe considering it is the weapon of Kronos.
