A few things are amiss here. What causes the triangle shaped holes? Use your knowledge of physics if applicable. If not, just come up with some DMCesque answer. Also, I'm going to need a bit more from you. Sure, it's not all that special of a weapon but this is not enough information.
I hate to be a nag, but could you please use spellchecker on your stuff? The spelling errors are affecting my judgement, and I don't want to be cruel.
