36 Clipless Click Pen - 6Al-4V Titanium - 464 Brass Mechanism - Cone Nose - ISO G2 Schmidt 9000 (Parker)

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 chamber to more properly fit variation and relative angle between the tip piece and the body in the Schmidt 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, conical nose section and grip grooves. The mechanism comes equipped with a black Silicone Nitride Ceramic ball. Tip details are extremely tight with a small land between the refill, and the conical section.

Extremely minimal and clean design coupled with the Schmidt EasyFlow 9000 M 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 0.100"- 0.101" 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.
