Anso Pen

Overview

Designed in collaboration with Danish knife maker Jens Ansø, this pen embodies clean Scandinavian design and precision engineering. What began as an ambitious idea—an ultra-slim, hexagonal pen using our Side Click mechanism—became a true manufacturing challenge that pushed our team to innovate. Through a process called polygonal turning, we achieved the crisp hex shape directly from titanium bar stock—something rarely done in pen making. The result is a refined writing tool that blends Jens’ design sensibility with Tactile Turn’s craftsmanship.

Specifications

Ink Refills

The Ansø Pen ships with an Ohto PG-105 blue ink refill, which uses the Parker-style format. This allows you to replace it with a wide range of compatible refills from other brands if you prefer a different ink type or color.

Unlike our other models, this pen body is drilled out to 6mm and only accepts Parker-style refills. A Pilot G2 will not work, even if trimmed down. For a refill to work in this pen, the diameter of the refill must be under .236" and the length must be 98mm legnth (3.86").

The pen is in no way hazardous, we simply include this warning to comply with California law.
