I don't know if greydog is a member on here but he is on the other forum and I got a brush from him that I absolutely love. I had him put a horsehair knot in it and it's just an amazing brush and gorgeous handle. It is hands down my favorite brush as the size of the handle feels like it was made just for my hand. Here are the pics.
You might find your brush maker HERE. Good looking handle! Generally a Pro Barber profile but exaggerated on the lower end. Nice turning work & the knot color complements the wood tones.
A very cool guy with talent on the lathe for sure. I have an olivewood brush from that he was kind enough to set a Maggard mixed knot in for me, I consider myself very lucky to have it.
