Is this what you are talking about? If it is, I would say that this for the "lazy", I hate to say that, but it really for people who just want to make a quick , presentable shave ice. I've learned from a lot of good shave ice stores, where they mostly use their hands and nothing more to shape the ice. This way the pressure applied is just right through experience where they can maintain the best quality possible and yet create a good appearance. Never had any complaints on that part, although you truly need to master it. I had once go with the so called "Ice Shaper" route , it was quick and effective. But , I realized the quality is just not as good as if it was formed using my hands as a shaping tool. Everyone's got a difference of opinion so it's just my two cents on this.
