My Tactile Turn Mover in titanium arrived today ! I have been looking forward to getting this pen I backed on KickStarter for a while. My favorite maker of this class of hand machined pens is of course Karas Kustoms. However one problem with my Karas Kustoms Retrakt is that it is too smooth. I find it hard to hold the pen for a long time. The Tactile Turn pens are famous for their special spiral machined into the grip section that makes holding the pen comfortable, so I backed their project.

How does it compare?

Because I have the Titanium Mover vs the Aluminium Retrakt, the Mover is slightly heavier, but not uncomfortably so.
The groves in the grip section really works well. The pen is much easier to hold and write with
The Mover comes with a really nice "case" (see photo). I think that is really smart packaging
The click machanism looks just like the one used in the Ratrakt

So are there any negatives? A few small ones:

The threading on the body (when you open the pen to access the refill) is not as smooth as the Retrakt.
It does not come with any additional spacers and springs. When I got the pen it comes with a Pilot G2 0.38 gel refill which is nice, but I prefer the Pilot Acroball refill (BRPV-10EF). I swapped it right away and used the spring I got from the Acroball body. Kara Kustoms ships their pen with extra springs and spacers.
The pen arrived with the refill clicked "in", and some ink has leaked out because of it
Finally - this is the only flaw that I find -- because of the spiral grove, the end of the pen has a sharp edge to it (see picture). I think that should be smoothed out.
