I'm new to wet shaving and am just using my new Merkur Futur badger brush. It seems that after the brush "bloomed" following my first shave with it that there are "straggler" bristles around the perimeter of the brush. I'm wondering if I'm putting too much pressure on the bristles when I lather up - I'm moving it in circles and up and down, and naturally the bristles collapse. Am I doing something wrong or are these perimeter bristles supposed to look in disarray? Using Futur razor with Porasco soap/Ocean Breeze soap by Muhle on alternate days. Is there a place to get Derby Blades other than Ebay?
