Being a big fan of the original Rubberset 400 Aluminum handled brushes, I had to see the the Razorock 400. I bought 2 of them from Itailian Barber and they arrived yesterday. I must say the handles are quite impressive. Heavier in the hand than the original Ribberset. Not sure what to think about the "Plissoft" synthetic knots. Like nothing I've ever seen. Silky soft, but seem to lack much backbone. I will update the review after a couple of test shaves. The handles are awesome and if I hate the brush, I'll just replace with a badger knot. They look and feel sweet. RazorRocks on the left and Rubbersets on the right.
