Rike Knife - Tyokutuk-S

Tyokutuk-S, Back to the Beginning

Tyokutuk-S is not just a smaller Tyokutuk.

It is actually the original Tyokutuk design.

Before the design evolved into the production version known today, its earliest form measured under 200 mm in overall length. That first prototype stayed with us long after development ended, not because it was unfinished, but because it offered something different.

More compact.
More discreet.
More connected to the hand.

Years later, after sharing the original prototype with friends and collectors, one thing became clear:

The original version still had a story worth telling

Familiar DNA

Tyokutuk-S preserves every defining element that made the design unique.

M390 Blade

Premium Bohler M390 steel paired with our signature multi-stage grind and bold geometric lines.

Integral Titanium Construction

Machined from a single block of TC4 titanium.

Not the newest method.

Still one of the most demanding.

Signature Ring

A defining feature carried over from the original design.
A symbol of continuity.
A reminder of where it all began.

Hidden Pocket Clip

Cleanly integrated, secure in use, and intentionally understated.

Triple Deployment

Front Flipper.
Reverse Flick.
Inertial Open.

Three opening methods, one unmistakable experience.

Refined, Not Recreated

While remaining faithful to the original concept, Tyokutuk-S introduces subtle refinements, including updated pivot hardware developed through years of experience.

The changes are small, The intention is not.

Because great designs do not stand still.
