Several years ago when I was returning to classical wet shaving, I went to Crabtree and Evelyn to see what they had in their nearby store. To my delight they had a selection of Edwin Jagger brushes made especially for Crabtree and Evelyn. I bought a Best Badger as I liked the shape of the handle and the price was very reasonable (center brush below). Somewhere in the back of my mind the issue of a smaller, stiffer brush being more effective with hard soaps came forward and this became the perfect brush. Shortly after starting back on the only true path to shaving grace, I had to take a trip to the east coast and decided that this was the perfect excuse to buy the little Edwin Jagger traveler's brush in Pure Badger (leftmost brush below). Both brushes have proven themselves to be worth their weight in gold. Finally, a couple of weeks ago the twin siren songs of Brush Acquisition Disorder and Save 20% came together and I scored the Super Badger on the right of the picture.
All great brushes. They do the job of building lather well and are not especially expensive. If you have always wondered about the difference in efficacy or feel presented by the different grades of badger, here is a reasonable way to satisfy your curiosity and get great lather generators in the bargain.
