[@Raijinslayer]that sounds like a good idea...so maybe like this?

Example
Indigo threw one of the two shield blades at a column of hot glass created by combining azurites sand control with Mars's energy control,the glass,still not fully hardened shattered into billions of pieces that flew everywhere

That's one idea,another could be to shape it into a spear with a mace like head and throw it making it shatter on impact,IDEAS R US
