36 Clipless Click Pen - 6Al-4V Titanium - 464 Brass Mechanism - Round Nose - Pentel EnerGel

New 464 Naval Brass clipless mechanism. Brass works better as a bearing material and makes the button action smoother. There is a tighter fit between the button stanchion and the mechanism body making it more resistant to binding from pressing the button on an angle. Improved mechanism button chamber features making button action even smoother. This design also incorporates improvements made to the most recent clipped mechanism. Stronger main spring for a more decisive clicking action. Larger refill chamfer to more properly fit variation and raised type on the Pentel refills. Proper allowance for the refill and spring and mechanism is able to operate very smoothly, without the rough action of the refill and spring translating to the button.

Made out of the tough and hard solid bar stock 6Al-4V Grade 5 Titanium and the lead free 464 Naval Brass for the mechanism. A single 0.36" (9.14mm) diameter grip and a rounded nose section. The mechanism comes equipped with a black Silicone Nitride Ceramic ball. Tip details will be the tightest yet, with the smallest land between the refill and the cone tip profile. 

Extremely minimal and clean design coupled with the very excellent and the Pentel EnerGel 0.7mm refill. Pinch the mechanism between your index finger and thumb to retract the mechanism with a satisfying snap. The click and return is very solid and super satisfying. Tolerances, fit and finish for the mechanism are very close.

Tip point details are very clean with an excellent tight fitting 2.3mm bore and a tolerance of just 25 micron to keep the refill tip exactly in place.

Higbee thread start to the pen body to make the thread action for replacing the refill better.

This version is 5.30" (134.6 mm) long, 0.36" (9.1mm) in diameter, and 23.6g (0.83oz)
