I have 2 of the cheapos too. Plastic covered handles. Weight and balance is way off. Honestly I dont like them. Ive noticed the larger Butterfly's always seem to spin better. The more weight the better. Im not very good at it but I do practice once in awhile. Of the 2 Dixie's I have the larger one is much easier to handle. They are both solid metal construction.
Even Benchmaid can be a pain depending on the materials and size.
Here is what I was wondering though.. How in the world did you cut yourself? Is it a kris blade or otherwise double edged? If it isnt and you're spinning it the right direction, there is no way you can cut yourself! Did you accidentally spin it the other way? The most I ever do is beat the hell out of my knuckles. I dont trust myself enough yet to try to spin a kris or double egde blade.
