Blade Finish

This Ultralight Caping and Boning Knife is built for hunters who need a stronger, stiffer ultralight blade for fast, clean caping and boning work. Designed with professional hunting outfitters, the double-edged point is ideal for fine caping work while the stronger, stiffer backbone cleanly powers through joints, tendons, and around the bases of antlers.

Crafted from the same premium A2 Tool Steel used across Iron Will’s precision engineered knife lineup, this ultralight knife offers incredible sharpness, edge retention, and reliability in the field - without adding unnecessary weight to your pack.

Ideal for hunters who desire:

  • A strong ultralight knife for joint and tendon cutting
  • Straight top, stiff blade for precision boning work
  • Narrow, extremely sharp point for fine, precise caping cuts
  • Premium steel and durability trusted by outfitters
  • Minimal weight with maximum performance

Lightweight. Razor sharp. Outfitter approved. The K4 is the ultimate caping and boning knife for serious hunters.

Additional Features

Natural Steel Coating

To protect from corrosion, Natural Steel blades feature a light mineral oil coating. A2 Tool Steel is not stainless, so we recommend applying a light treatment of wax or mineral oil to blades after use.

Black Steel Coating

Our Black Steel option features our same A2 Tool Steel blades treated with a black composite coating for additional wear resistance, reduced friction and enhanced corrosion protection. Though more corrosion resistant than our Natural Steel blades, A2 Tool Steel is not stainless, so we recommend applying a light treatment of wax or mineral oil to blades after use.

G-10 Handle

Precision CNC machined from G10 and at only 0.7 ounces, this handle adds extra control and comfort without contributing significant weight. G10 provides a confident grip when wet or dry so you can finish the job safely and efficiently.

Skeleton Handle

For the backcountry ounce counter, simply throw the skeletonized knife with sheath in your kill kit and you’ll forget about it until you punch your tag. For added grip and backcountry readiness, wrap your handle with the included paracord.

Kydex Sheath

The lightweight and minimal Kydex sheath included with every knife keeps your blade secured, out-of-sight and out-of-mind when you don't need it. And with exceptional durability, it's ready for all the blood and frequent use you can throw at it.

Pack Attach Sheath

Designed to fit straps from 1.5" to 2.25" wide, the Pack Attach Sheath is perfect for mounting your Iron Will knife to MOLLE webbing, to your backpack's shoulder straps, or your pant's waist belt. This external knife attachment features multiple configuration options for left- or right-handed knife access, plus dual locks so it won't shake or come loose.

Sharp Edges that

Stay Sharp

Iron Will knives are engineered to be extremely sharp and stay that way. A2 Tool Steel, which is commonly used by manufacturers to stamp metal, is treated with our proprietary cryogenic steel hardening process to produce edges with 60 HRC hardness. The result is a reliable blade you can count on to completely debone and field dress big game. So you can spend more time cutting and less time resharpening.

A STRONG BACKBONE FOR

POWERFUL CUTS

Wild game is tough. The K4 is engineered to give you the power and control needed to work through joints and tendons with ease, including the difficult areas around antler bases.

“The K4 lets me break down my clients’ bears fast and clean during our spring hunts, while ensuring the hide and trophy are in perfect shape for the taxidermist.”
