I bought the sharks tooth brush. I bought it on 1/7 and received it today, 1/11. While the brush was in transit I was talking with the maker about ideas for other brushes. I asked about the knot, and he was unsure what that meant.
He buys them from here

overall a nice person who has some skills with a lathe, which he uses exclusively. However he does not know a whole lot about brushes.
First impression was that it an extremely nice handle, not too sure about the actual brush. I was expecting a cheap knot, but it was softer than I expected. At first I only lost a few hairs, maybe 5. I washed it and thought I would use it the next time I shaved. I could not wait so I put it to soak while I decided on what soap to lather. I emptied my mug, to see that the all of the water had turned a purple color. I thought that was odd. So i soaked it again, and again. I thought I had gotten out whatever was turning the water purple, I started working a lather. My lather had a slight purple color to it, so I rinsed it again and put it to soak, again.
My expectations were low, I really liked the handle and was expecting a cheap brush. I've probably lost about 10-15 hairs each time I've soaked it, but they are easy to pick out. I'm currently on my 5th or 6th soak.
All of the problems I have with the brush are not his fault. With a bit of education and a better source for knots he can become an excellent brush maker.
