[Steve Plambeck]

Picture a flint dagger blade mounted to a wooden handle.

The handle could be a Staff, and none the wiser.

Of course copper or bronze would work for the blade as well, but a flint blade can be tapped out to be even sharper than a modern scalpel! Our ancestors were pretty smart :)

If anything, a flint dagger blade might do an extra point of damage, but it would be more prone to breaking.
