CR2870: Kommer I.F.B.™
Columbia River


Russ's Integral Fixed Blade is simple and just about indestructible, ready for special forces use with a multi-position quick-release sheath.

Here’s a knife designed by Russ Kommer
for special forces units. He knows that operators want a knife that gets right to the point. So there are no bells or whistles, nothing to break or fall off. Instead, it is a single hot-forged piece of carbon steel that is just about indestructible. We call it the Kommer Integral Fixed Blade, or I.F.B.™

Steels in their as-cast or bar stock state have randomly oriented crystals and occasional defects such as voids and inclusions which can create weak areas. In hot forging, we heat 6168CrV carbon steel to 1,000 degrees F and force it into a die under pressure. The resulting plastic deformation refines the grain structure and improves the physical properties of the metal, including its strength, ductility and toughness. After finishing and heat treatment, we arrive at 59 to 61 Rockwell hardness for great edge-holding ability. Finally the knife is given a black EDP non-reflective coating to resist corrosion.

The I.F.B. design uses a modified drop point 3.82" blade, taper ground for maximum strength. The handle is wide to give a secure grip, and is contoured to fit the hand. It is fully skeletonized to reduce weight, and ample smaller holes allow the operator to fit a lanyard or to cord wrap the handle if desired. At 7.7 ounces, the I.F.B. has very good balance for a one-piece knife and enough heft to aid penetration.

Tactical Sheath. The I.F.B. comes with a custom-molded black Kydex® sheath with a detent which firmly grips the knife, allowing inverted carry. The sheath uses our patented* multi-position quick-release clip, which can be attached with Chicago screws for vertical or horizontal carry on belts, webbing or equipment. To remove the sheath, you simply squeeze the locking clips together and pull up on the flexible tab.

There you have it. Not much poetry here. This is a knife with a mission, and it’s designed to take abuse that most other knives cannot tolerate. Gentlemen, you have your orders.

About the Knife Designer
Russ Kommer of Fargo, North Dakota, has been a commercial hunting guide since 1980. He started making knives when one of his hunter clients brought a custom knife and dressed an entire moose without sharpening it. He began working with noted Alaskan knifemaker John Shore, who took Russ into his shop and showed him how to grind. He began making his own line of knives in 1997, and his custom catalog shows a range of fixed blade knives, including Bowie and Camp Knives, Fillet Knives, Hunters, Fighters and Boot Knives, all available with a variety of exotic handles and with engraving. He is the designer of the CRKT Bear Claw, Big Eddy, hunting knives including our Pro and Signature Hunters, 30-30, and Surf ’N Turf, plus the Kommer Fulcrum and I.F.B. He says, “I set out to make a quality knife that would perform and be comfortable to handle. I have found knifemaking to be my calling, and would like to thank all the people who have helped me along the way!"
