Some collaborations happen because they're planned. Others happen because they simply make sense.

From the first conversation, it was obvious both brands shared the same philosophy—clean design, premium materials, and products built to be used every single day. The result is a collection that feels familiar to fans of both brands while bringing something entirely new to the table.

This limited edition collection includes two of our most popular writing instruments: the Fountain EDC and the Base Line Bolt Action. Both are precision machined from solid titanium and available in our signature Stonewashed finish and stealthy DLC Black.

The Fountain EDC features a premium German-made Bock 180 Extra Fine nib, an addicting pull-cap design, and compatibility with international ink converter for an exceptional writing experience.

The Base Line Bolt Action delivers the satisfying action our customers know and love, paired with seamless compatibility across hundreds of popular Parker style refills. Clean lines, dependable performance, and everyday reliability make it a pen you'll reach for every day.

Whether you're a collector, a knife enthusiast, or simply appreciate thoughtfully designed tools, this collaboration brings together the best of both brands in a pair of writing instruments built to be carried, used, and enjoyed for years to come.
