The Backstory

Written by Will Hodges

My father was a cabinetmaker before he met my mother and joined her architectural scale model company and had a deep appreciation for modern Danish furniture. Clean design, great materials, and proper craftsmanship is part of the culture and no one exemplifies the attention to detail better than the legendary designer, Jens Ansø. I remember seeing some of Jens' knives at Blade Show Atlanta back in 2017 and loving them but I was too intimidated to introduce myself. Imagine my surprise when Jens reached out about a pen collaboration in August 2024. I immediately sent the initial design specs to the team, picked my jaw off the floor, and set the wheels in motion.

Our first formal meeting was at Blade West later that year where he showed Kevin and I his prototype and we started talking through how to make it happen. He wanted a VERY slim pen with a hexagonal body which is much more difficult to manufacture than it seems.

Slim pens on their own are difficult and Jens wanted to go significantly slimmer than anything we had done before and utilize our Side Click mechanism, requiring plenty of iterations to get right. On top of that, the hexagonal body was a bigger challenge than expected. Most of the time, hexagonal-shaped pens are made from extrusions of aluminum or brass which is straightforward. Titanium hex is a different story and the suppliers that were willing to do it required huge orders which we didn't feel comfortable with knowing if the tolerances were even slightly off we'd be sitting on a lot of very expensive scrap.

Instead, our solution was polygonal turning which involves timing a cutter and the rotation of the material just the right way to produce different shapes. I won't bore you with too many details but I will say that there were some serious barriers in changing DEEP internal settings in the machine that ran these that will keep most other machined pen makers from doing this. Credit to Kevin's incredible knowledge and experience to make this happen.

This pen is a result of an amazing collaboration – Jens came up with something quite difficult and the team stepped up to make it happen. I couldn't be happier with the results and I know Jens feels the same way.

Designed from the ground up

While it may resemble our typical Side Click models, the Ansø pens feature a special, slimmed-down version of the mechanism to fit the even "slimmer than slim" body diameter. The knurled grip and hexagonal body sections are new additions to our catalog which required using new (to us) tools and plenty of trial-and-error. One immediately obvious change is the side button to retract the ink refill is located on the opposite side of the clip.

One length, multiple materials

Because of the slim diameter constraints, the Ansø pen only accommodates Parker-style refills and comes in a single length equipped with an Ohto PG-105 0.5mm blue ink refill. For the initial batch, we're excited to offer the pen in both Stonewashed Titanium and Brass which adds a bit more heft and will patina over time.

New Finish

Blackened Brass

For this brand new finish, we applied Black Cerakote paint to the brass pen before running it through the tumbler. Due to the polygonal nature of the Ansø pen, the brass shines through on the edges and knurled grip to create a striking look.

Note: The finish will continue to change over time.

    Nice and slim.

    The bottom part is very slim but the knurling gives it a controlled grip.

    The click is firm and satisfying. Overall not too heavy and well balanced.

    And as usual with TT no tip wiggle.

    The Pen I've Been Looking For

    I love pens, especially pens that were designed to be held, to be used. Pens that are true tools yet dispaly a deep undstanding of form as well as function are rare.

    For many years now, I have been using pens that were hexagonal in shape with a small amount of knurling at the end. They are nicely done and have served their purpose well. But when I saw images of the Anso Pen in Titanium, I was intrigued. Ordering one from Tactile Turn and getting it in hand only increased my appreciation. The pen is light but still substantial enough. It looks and feels like a real tool. The hexagonal portion of the body is shorter than on my ususal Rotring pen, while the knurled portion is longer.

    In hand, it becomes immediately apparent that Anso paid very close attention to where and how the pen actually sits in the hand. His placement is much more comfortable than my other pens. Once I had used it for a week at work, held it, and looked at it, I decided that I really did need the optional titanium Damascus clip. Once ordered, it arrived quickly. It looks spectacular on the pen!

    Incredible

    This pen is incredible. I replaced the original cartridge with a Parker ball point. Just preference reasons but the fit and finish is unreal. My only negative is that I want another 200 dollar pen in brass

    Great pen

    I had brass body version for 3 months and couldn’t be happier with it. The very slim hexagonal body, combined with the weight of brass feels great. I tried the titanium body, but I didn’t like the way it felt when writing. It didn’t have enough weight for me.

    Exquisite balance, current go-to pen

    I have the brass pen (waiting for the titanium to be in stock to pick up one of those as well) and it very quickly became my go-to pen. The balance of the pen in the hand is (at least for my preference) essentially perfect. It feels weighted a bit toward the upper part of the pen in the hexagonal body, but not overly so. I like the center of mass of a pen to be right where it rests between the thumb and the hand, with the grip feeling slightly lighter at the grip, and this pen is on the money. I should note that I tend to write by moving my thumb and index finger rather than by moving the whole arm with the thumb and index finger lightly gripping the pen (the latter being what you're "supposed" to do to reduce hand fatigue when writing). I'm like the Schneider refill it comes with, but I'm currently using a blue Monteverde P41 ceramic needlepoint extra-fine gel refill (generally my preferred Parker-style refill). My great thanks go to Jens Ansø and Tactile Turn for producing a pen that's such a joy to write with!

    One final note: Do *not* use the Parker-style adapter that comes with the Fischer Space Pen refills, as it will get stuck in the upper barrel. You can make a Space Pen refill work by taking the top off the Schneider refill, trimming the bottom that usually sticks inside the top of the refill, and setting it atop the Space Pen refill to act as a spacer.

    Love this pen!

    This pen ticks all the boxes for me - slim, side-click, easy-to-find refills, and a nice knurled grip section. I hope someday there is a pencil version!
