Add a smishing templates for weapon shapes

Please consider adding smithing templates to Minecraft that can alter the appearance of weapons and tools.
Minecraft weapons can look a bit monotonous, so it would be nice if there were rare smithing options to slightly change their shape.

For example, swords could be changed to katanas, or pickaxes to single-pronged pickaxes.
(However I think changing it too much would spoil the vanilla feel)
