Boye Cobalt Basic 3 Fixed Blade

The Boye Cobalt Basic 3 Fixed Blade is a powerful working knife, designed for maximum versatility, strength, and compactness.  An all around survival knife, it excels in the ocean environment, where it cuts tough line like butter, keeps cutting for hours, sharpens quickly, never rusts, and won't affect a compass.  This combination of key features is unique in the knife industry.  As you use the Basic 3 it quickly becomes apparent what a useful and sublime multi-tool it really is, with a wide range of applications.

ORIGINAL, ADVANCED FEATURES

Practical Blade Shape

The Basic 3 has a "dropped edge" blade design - the edge drops down below the fingers forming a finger guard.  With this design, the entire edge is brought into service for the most common action of a knife - cutting down onto a flat surface, while the fingers are kept safely out of the way. This concentrates pressure along the whole length of the edge, empowering the cut.

 

 I-Beam Strength

Cast in one unbreakable piece of Boye Dendritic Cobalt, the Basic 3 has I-beam anatomy to minimize weight.

Scrape Edges

The back of the blade is ground to form two sharp 90 degree angles, tough "scrape edges," which can be used to scrape paint, plastic, fiberglass, wood, or most other rough surfaces, including rust on metal. The scrape edges can be sharpened on the same whetstone as the blade, and take a new edge quickly.

Multi-Functional:  Cut, Pry, Hammer

The Basic 3 also works as a wedge and a pry bar (with care).  The butt of the handle and the back of the blade can also be used for hammering. 

Sharpening Angle Guides

The sharpening angle guides are at the base of the blade and provide guidance for placing the blade at the correct angle on a stone.

Wrapped Cord Grip

The cord wrap on the handle is a 7 foot piece of 225 lb test strength accessory cord.  Aside from providing a long lasting, good grip, the cord can be cut off for emergency use for anything from a fish jigger to a tourniquet.

Kydex-lined Sheath

The Basic 3 sheath is slim, discreet, and lies flat against the body, making it easy to move around in tight quarters.  The velcro flap can either be closed over the handle or folded backwards and tucked in for easy deployment.  The knife slides into the sheath with the blade facing in either direction. The Kydex liner fits snugly into the webbed pouch, and pulls out for cleaning.  It can be spread open and rinsed or shaken out so sand and dirt won't build up over time and dull the tip.

    Using the Basic 3 On Your Boat

    Working with lines: If you don't have easy control of the lines, control of the boat itself can be compromised. No other metallurgy that we know of outcuts or stands up to high tech lines like dendritic cobalt. Cleaner cuts make for better splicing. The Cobalt Basic 3 has a superb edge and keeps it.

    Easy carry: The flat shape of the knife and sheath will be appreciated especially in tight quarters. The knife can be worn on a belt vertically, with the hood open (folded back) to be handy and visible, or securely closed, or deployed horizontally.

       This knife cuts phenomenally, keeps its edge and won't rust!
