I love my two Muhle synthetic brushes, as well. Out of 20 brushes, they are my mainstay for the last few months. The Kawashima is a terrific razor. I got it from Takeshi Aoki from http://www.aframestokyo.com. He's in Honolulu, Hawaii. I think he had two more last I looked as well a few other Japanese razors.
Nothing fancy, but I like it very much. Dovo Best 6/8 half hollow & the RazoRock Fresco seem to be best friends so far.
+1 Thank you for posting Archi. I've been thinking for quite some time on what my 2nd new razor should be. I'm now certain.
