Oh? Ok. I've never heard of that before. I've only heard of flour. What is blood stop powder? Is it something you can make, or something you can buy? I'd like to know more information, if you don't mind. :)
On toenails, I just use regular nail clippers. (Make sure they're sharp first.) Clip around the edges and be sure not to cut into the quick. If you do accidentally cut into the quick (it's a common mistake), use flour to stop the bleeding. It works well. On the trim, you can also use a file...
