I got to see some of Red Blossom's new gaiwans when I stopped by the shop recently. Beautiful, but I could never justify buying one because first of all, I'm a broke college student and second, I break way too many gaiwans!
That new Celadon gaiwan http://www.redblossomtea.com/teaware/gaiwan/celadon-gaiwan-2012.html, looks like it would kill my fingers, unless I switched to using the saucer when I pour. Oddly that gaiwan looks like the saucer is made to intentionally make it easier to use the saucer when you pour. I am betting I could almost use it similar to a houhin.
