45 Clipless Click Pen - 6Al-4V Titanium - Conical Nose - Pentel EnerGel

Please note there is a limit of one item per customer for this release. I have a batch of these ready to go now for immediate shipment. It will take me a few days to get them all shipped out after the release. More stock will be offered in the future. Send me an email if you are interested in this model, and missed out. I will tally up those emails and make extra for a second offering. Thanks for following along, let me know what you think about this design and send requests for future designs.

Conical nose design in a new 0.45" diameter with a new re-designed clipless mechanism. Revised work holding and setup process keep mechanism details better in line than previous designs. No o-ring bumper for this design. Spring rates are pretty optimum removing the need for the bumper. Uses a larger 4mm (0.1575") bearing ball and the same smaller diameter secondary spring. 

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 smoother. 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. A single 0.45" (11.43mm) diameter grip, conical nose section and continuous body finish with texture for grip. The mechanism comes equipped with stainless steel bearing 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 Metal Nose 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. Added a new locking feature that should keep the mechanism from unscrewing without the need for an o-ring or loctite.

This version is 5.33" (135.38mm) long, 0.45" (11.43mm) in diameter, and weighs 42.2g (1.49oz).

Pens will ship over the next few days. Hopefully there are more to accommodate the demand. Thank you again!
