Inspired by the legend that sailors were once asked to break off the tip of their blade, the Iona Sailor combines maritime heritage with modern manufacturing methods, resulting in a swashbuckling, EDC-inspired design.

Building upon the legacy forged by the Iona and the Iona v2, the all-new Iona Sailor blends the best of both versions: returning to the original V1 sizing while keeping the improved liner lock access for ease of use. The new Sailor variant features an S90V blade, Fiberglass Reinforced Nylon (FRN) handles, and ambidextrous thumbstuds/pocket clip mounts that allow left- and right-handed users to customize how they carry their gear, packing a lot of value into a knife that retails for just $175.

Arguably the most important aspect of a pocket knife, the Iona Sailor features a S90V blade, a choice that complements the overall swashbuckling theme of the knife well. Available in either a satin or stonewashed finish, S90V combines several key properties that include corrosion resistance, edge retention, and wear resistance to create a well-balanced steel that’s a great choice for EDC. Its ability to hold an edge for prolonged periods makes it a go-to material for premium knives aimed at collectors and users demanding the highest performance.

Legend has it that, in the sea-faring days, sailors were once instructed to snap the tips of their swords off, making them tools of utility rather than tools of mutiny. Leaning into this legend, the Iona Sailor features a modified Sheepsfoot-blade with a blunted tip and a long, sweeping blade that excels at controlled slicing. This combination of blade shape and premium steel respects the tradition of a blade as a utility tool, prioritizing a hardworking edge.

While having a great steel for the blade is important, having a solid handle to grip the knife allows it to be useful. With this new variant, GiantMouse has introduced a new handle material to their lineup: Fiberglass Reinforced Nylon. Commonly referred to as FRN, this material can be injection molded into unique shapes while remaining lightweight. The curved shape and “scalloped” texture of the handles allow for a secure grip, even when wet, something that’s equally important on land or in stormy seas.

Since GiantMouse formed in 2015, they’ve become a powerhouse of the EDC industry, and for good reason. Originally working with two legendary Danish designers, Jens Anso and Jesper Voxnaes, American entrepreneur Jim Wirth created the perfect combination of “Danish Design, American Spirit”, the motto they operated under for roughly 10 years. During this time, the GiantMouse team set down roots and proceeded to release iconic designs such as the Riv, Jutland, GMF4, GMX, and the GMF1-XL: many of which have won prestigious awards such as “Best Factory Fixed Blade”, “Knife of the Year”, and “Best Hunting Folder”. Beginning a new chapter with Jesper and Jim at the helm, Giantmouse continues to release exciting new models and even update iconic pieces from the ACE collection, as they’ve done with the Iona.
