I'm completely new to straight razor shaving but I've been a wet shaver for awhile. I recently bought a Vikings shave brush and have only used it once so far. But so far so good. I like the feel of it and it has a good knot that picks up soap well and it didn't lose one hair the first time using it. Any thoughts on this brand? I also had a question. I haven't had a chance to handle various brushes but it seems they are pretty straight forward. What is the difference between a $39 brush such as my Viking and a $200 USD brush? I mean in terms of performance and not aesthetics.
