Extreme edge holding
Boye Dendritic Cobalt blade with carbide crystals for unsurpassed edge holding and fast, clean cuts. Sharpens quickly and easily on an ordinary whetstone.See our cutting demonstrations.
No rust, ever
The blade and all fittings will never rust, even after months or decades at sea, or through miles of marathons and hard workouts.
Non-magnetic; compass safe
Does not pick up a magnetic charge, and so cannot affect a compass or sensitive electronics
Sharpen in seconds
Sharpening is fast (but rarely needed). Knifemaker David sharpens his daily carry once or twice a year with just a few strokes on the whetstone.
Lightweight and compact
Surprisingly light at 2.5 oz, the knife lies flat against the body and won't get hung up while you're moving around.
Either hand opening and closing
The blade can easily be opened and closed using either the right or left hand. The flat base at the bottom of the blade keeps fingers safe and away from the cutting edge when the blade is being closed.
The back of the folder 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. On the Pointed Tip Folder, the combination of the blade edge and the scrape edges work in tandem to drill holes. The scrape edges can be sharpened on the same whetstone as the blade, and take a new edge quickly.
Incredibly effective at endurance cutting, the serrations stay sharp and take a fresh edge quickly on an ordinary whetstone.
Two blade finishes
Our sheepsfoot and pointed tip dendritic cobalt folders are available in two blade finishes. The blades are the same, only the surface finish is different.
As-Cast finish - Our most economical option, the as-cast blade bears the impressions of its birth from a molten state. The blade takes on superficial metal flow lines and the natural grain texture of the porcelain mold as it cools. The surface is smooth to the touch and does not trap dirt or food.
Hand Polished finish - The internal carbide crystal formations in the blade are clearly visible in the frost-like damask on the blade surface. The hand polished blades have a more refined look, moving into the beautiful.
Both blade types have a smooth, lustrous finish. The upper portion of each blade is hot stamped with a magnified image of the dendritic carbide crystals.
Safe Grip Handle
Made of strong, fiberglass-filled nylon (Zytel), the handle design keeps the index finger safely away from the knife edge and is textured for a no-slip grip. The textured pattern is a magnified picture (300 X) of the carbide crystals in the blade. The handle stays at a comfortable temperature under all conditions, i.e. doesn't get hot or cold in your hand regardless of the weather.
The blade release bar, also known as the rocker arm, has a scallop-shaped recess (the "Boye Dent"), preventing accidental disengagement of the blade when the handle is gripped tightly.
Forged 2 point titanium pocket clip (Chris Reeve design) keeps the knife held firmly, yet allows for quick deployment with either hand.
100 lb test 304 stainless lanyard loop for tethers or accessories. Doesn't swivel into the path of the closing blade. A Photon Freedom Micro LED is highly recommended on the loop!
Titanium Marlinspike/Shackle Key/Multitool
The Marlinspike/Shackle Key/Multitool (the "spike") greatly expands the usefulness of the knife. The flat sides and edge do the work of prying large and small knots open. A round spike can slide sideways, and doesn’t have the same ability to grip and unlock a really tight knot. It also separates strands for splicing, pries up boards, opens and closes shackles, and works hard at the many tasks that the blade should not be called on to do.
The spike lies flat on the handle, doesn't hang up in the pocket, feels smooth against the hand in use, and improves the grip. It swivels open under finger pressure to a strong anchor stop pin, facing in the correct direction to unscrew shackle keys that are stuck closed. The handle of the knife doubles as the handle of the spike, providing plenty of leverage when the spike is open to maneuver, press into hard knots, or loosen tight shackles. It rotates to a closed position stop pin and stays firmly in place until the next use.
The spike will pry up to 200 lb (be careful) and can serve as a digging tool when you really need one. The shackle key is a wrench for anything that will fit in it.
“I use the spike twice as much as I use the blade." - Eric A., car mechanic
