I just had a Moori Medium tip put on, which this is my first Moori tip that i will be using, and when i got it back it was still square as in he did not shape it. He told me thats how they are suppose to be. I just wanted to be sure that Moori's are to be shaped like anyother tip, to about the nickle/dime radius that i like, right? Is there any precautions i need to worry about shaping it my self?
