Master the art of sharpening!
Discover the superior sharpening that only a stone can provide. The Work Sharp® Whetstone provides consistency and control in traditional knife sharpening, thanks to built-in angle guides and a sharpening base designed to hold water and reduce mess.

Classic sharpening, made easier.
The Whetstone Knife Sharpener brings the authentic feel of a water stone into the modern era. The dual-grit stone (1000/6000) allows for both sharpening and honing, while the water-controlled base keeps your work area clean and stable.

Removable 15° and 17° angle guides help maintain a consistent angle, ideal for both those new to sharpening stones and those who want precise, repeatable results.

KEY FEATURES:
Double-grit water stone: 1000 grit for quick edge restoration and 6000 grit for a polished, razor-sharp finish.

Base with water control and non-slip feet: keeps the stone firmly in place and reduces splashing, making sharpening cleaner and easier.

Removable angle guides: help develop the correct technique for precise sharpening at 15° or 17°, eliminating uncertainty and allowing you to achieve a professional-grade edge.

TECHNICAL NOTES FOR ENTHUSIASTS:
The combination of 1000/6000 grits allows for balanced sharpening progression: 1000 is ideal for restoring the edge profile and correcting micro-chips, while 6000 allows for a fine finish that improves cutting ability and smoothness without compromising edge durability.

The 15° and 17° angle guides reproduce the geometries commonly used in kitchen knives and high-performance knives, providing a constant and repeatable reference. The stable base and water control promote smooth strokes and uniform pressure, key elements for achieving a symmetrical, continuous, and technically correct edge.

Based on the best-selling Precision Adjust knife sharpener, the Precision Adjust ELITE is an angle-adjustable knife sharpening system with seven abrasive grits that offers precision and repeatability for sharpening enthusiasts who want the best in hand sharpening.

Sharpening angles can be adjusted from 15° to 30° in 1° increments to suit a wide range of kitchen, outdoor and EDC knives. Supplied with diamond grit plates and a fine ceramic for repairing, sharpening and polishing to an incredibly sharp edge. Then the leather quill refines and polishes the edge for even more extraordinary results. The included ceramic rod sharpens serrations.

Innovative V-Block clamp design locks the knife quickly and securely during sharpening. Tri-Brasive® case and holder keep abrasives and sharpener neat and ready to use wherever your adventure takes you.

From repair work to reprofiling your favorite EDC to mirror polishing any blade, this sharpener offers the ultimate in performance.

- It includes the Precision Adjust sharpener and upgrade kit in one package.
- Sharpener with rod and clamp designed for ease and safety.
- 15° to 30° angle guides
- Includes 220, 320, 400, 600, and 800 grit diamond plates, ceramic plates, leather clamp, and ceramic rod for sawing.

Introducing the new Model 451 full-tang fixed blade field knife, designed and made by Freeman Outdoor Gear LLC.

The CerakoteTM coated LSS PGK steel drop point blade features a main flat grind with a thick secondary swedge for maximum toughness and piercing ability.

The exposed pommel with jimping acts as a flat hammering surface and includes a lanyard attachment hole sized for the included 550 cord lanyard. 

The blade is heat treated and double tempered to a hardness of 59-61 Rc and the cutting edge is ground razor sharp at a 40 degree included angle (20 degrees per side).

The handle scales are CNC machined from tough G-10 or optional Canvas Micarta with milled grooves for a secure and comfortable grip. The handle shape provides an ergonomic and balanced grip for use in multiple positions. Enhanced parrot's beak pommel and lower front guard aid in blade retention during chopping. Stainless steel hardware locks all the components into place.

Included is a Spec-Ops Brand fabric sheath with thermoformed puncture-proof kydex lining.

Note from Jeff: Before joining the US Army, I worked for 5 seasons as a wildland firefighter based out of Sweet Home, Oregon. While there, I battled scores of wildfires throughout Oregon and the Western United States with a very skilled, hard-working and dedicated group of young men and women. My crew's radio dispatch call sign was "451". 

I've named this knife family the "Model 451" in honor of those crew mates past and present that put it all on the line for the protection of our wildlands.
