Yeah, but his very form and everything was based around the principle of the hands, so he would feel a bit uncomfortable to just forgo it and use an ice magic in a different way. Plus he only had it for a short while, I don't think he knows the ins and outs too well so he could be using it in conjunction with his regular magic.
