Behind the Design

Most ballpoint pens interrupt you. To extend the tip, you shift the pen in your hand, click the top or side button, then reposition. It takes less than a second, but it costs a beat of concentration.

KITERA's SideKnock eliminates that pause with a different approach: bending the barrel itself. The pen is engineered with a hinge at its midpoint, so a gentle flex in any direction along the horizontal axis engages the refill. Because the motion is built into the barrel form rather than a discrete button, your fingers stay in the same position throughout. No regripping, no repositioning.

The barrel is machined from brass and steel, materials chosen for their weight and rigidity. That mass makes the bending action feel deliberate and controlled rather than accidental. The 4C refill format keeps replacement straightforward, with a wide range of compatible refills available from multiple manufacturers.

Instead of clicking the top, you bend the barrel to extend the tip. The hinge mechanism works across a full 360 degrees, so you can activate it from any angle without shifting your grip or breaking your focus.
