Designer note

A small knife should still feel complete.

Designed by Jake Diaz (Happy As Larry), the Spud is built around a simple idea: make the small knife feel complete in the hand. The rounded aluminum handle, thumb stud deployment, and broad drop point blade keep it compact without making it feel temporary.

Three finishes

Pick the profile that fits your carry.

Choose from Champagne, Gray, or Black aluminum handles, each with the same compact Spud profile and a distinct blade finish.
