40 Clipless Click Pen - 6Al-4V Titanium - 6061 Aluminum Mechanism - Step Nose - Pentel EnerGel Needle Nose

New body diameter with an all new diameter mechanism the includes all of the improvements to previous versions plus a few new ones. Retract mechanism is easier to push the spring rate is more preferable for a slightly larger diameter mechanism. The knock back effect from the main spring has been reduced with more room allowed for spring at the end of the body.

The 6061 Aluminum clipless mechanism, is bright and smooth. There is a tight 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. There is now a single detent track that improves the button bias depending on which side of the button is facing forward. Larger refill chamber to more properly fit variation and relative angle between the tip piece and the body in 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 bright 6061 Aluminum for the mechanism. A single 0.40" (10.16mm) diameter grip, stepped nose section and grip grooves. The mechanism comes equipped with stainless steel balls. Tip details are extremely tight with a small land between the refill, and the conical section.

Minimal and clean design coupled with the Pentel EnerGel Needle Point 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 diameter 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 5.33" (135.38 mm) long, 0.40" (10.16mm) in diameter, and 29.0g (1.02oz)
