Ordered one more yesterday, a Tactile Turn Shaker in stainless steel. If Thomson made a pen, it would look exactly like these Tactile Turn pens. As an unabashed Thomson fanboy, the temptation got to me.
These have been mentioned before in this thread, but I don't think anyone has mentioned that Will is now making his own mechanism for them out of titanium. The original version used the brass Schmidt mechanism which can wear out. And, with his own mechanism the tip retracts further into the pen so it shouldn't get ink on your clothes if carrying it around in a pocket.
And if you have a pen using the old mechanism (Karas and others use it as well),
these folks make an all-stainless version if you want to upgrade.
