This question is usually the first thing people ask about.
The Slider is slightly shorter and comes with a Schmidt Easy Flow 9000 medium point with black ink and will fit all other "Parker style" refills.
The Glider is the slightly longer version that comes with a 0.38mm Pilot G2 with black ink refill. These are a little easier than the old pens to allow refills to fit and most require no modification at all for many different refills.
Both pens fit well in almost all hands, though if you have larger hands you might be more comfortable with a Glider. Sliders tend to fit better in shirt pockets without sticking out.
Tactile Turn was one of the first fully machined pen manufacturers. We don't do injection molded parts like most other pens. We make parts one by one on our computer numerically controlled lathes in our own shop in Texas. We buy the best equipment available, the best material available, and turn raw materials into finished goods. We never skimp on quality, as everything we make is designed to be an heirloom quality item. We want you to pass these on to your children. People buy Tactile Turn pens because they want an item with simple and elegant design made from amazing materials that will withstand daily use for life.
Tactile Turn pens are known for their texture. It's where our name comes from. The tactile feeling when you pick one of these pens up is hard to describe, but it allows you to control the pen exactly the way you want. Machined pens often forget about grip, or have uncomfortable grips. It won't bite into your skin, but it provides just the right amount of grip. It is subtle, but it also protects the pens from light scratches by providing a textured surface that disguises light scratches much better than a smooth surface.
The main piece that makes these pens really interesting is the bolt action. I use a shape unlike any other pen out there. It is one fluid motion to advance or retract the refill. Because the surfaces of both the interior part and the inside surface have been carefully machined to be extra smooth, the action feels amazingly satisfying.
Standard vs Damascus Bolt
Damascus steel is two alloys of steel put together in different patterns, that when etched in acid reveal the pattern. One alloy darkens where the other stays the shiny color. The bolt for the bolt action is the part that you push to advance and retract the mechanism. The standard bolts work just the same as the Damascus versions, but the Damascus version is a small detail that looks really cool. Damascus steel material is incredibly expensive, so most people do not want pens made entirely from Damascus, but we offer this detail as an upgrade.
Physical vapor deposition coatings are extremely tough coatings that are mostly found to improve wear characteristics on machine tools. Since the coatings are quite expensive they also are found on high end watches. We've been doing the DLC coating for a long time and there are lots of other colors that are available with PVD coating, so we sent off a batch. I was told these would be rose gold, but really the bronze color is fantastic and I'm happy to make them available for sale.
Titanium is the best selling of all of the materials we work with. It is not quite as light weight as aluminum, but significantly lighter than stainless steel, brass, and copper. Titanium is tough, lightweight, and extremely corrosion resistant. All parts of these pens are made from titanium except the clip which is stainless steel. If there is one material I suggest over all others, it is titanium.
