It looks like a hybrid of a kiljar & a falchion - with more of an arc to the blade it swould be a scimitar - the blade shape, being a historical reproduction swouldn't be copyrightable, but the design on the blade, if a faithful copy, might. I'd change that. Also the Pomel and crossguard fillials could probably be modified without too much trouble. Then there'd be no cause for concern, because that's all the dozens of sword-reproduction companies do for theirs.
