CR2605: A.B.C. Operator's Model
Columbia River

Jim Hammond is an active outdoorsman as well as a custom knifemaker and Knifemakers' Guild member. When his diving and whitewater friends pointed out the need for a better multipurpose fixed blade, he developed his custom A.B.C. (All Bases Covered) knife/sheath system. The CRKT production versions are faithful to Jim's designs and priced to put them within reach of everyone who depends on a knife for work, survival and rescue.

The dual-grind Tanto A.B.C. Operator's Model is an ideal general purpose fixed blade for special forces operators, as well as hikers, climbers, pilots, parachutists, and military personnel.

The bottom hollow ground Razor-Sharp edge is suited to fine cutting tasks. The top Combined Razor-Sharp and Triple-Point™ Serrated edge is ideal for rapid rough cutting through cord, nets, and other entanglements.

The blade is a full-tang skeletonized design of premium AUS 8 stainless steel. For maximum corrosion resistance, the steel is first mirror polished to close the pores, and then black titanium nitride coated. The finger choils are heavily friction grooved for sure grip.

The black injection-molded Zytel® scales have an aggressive texture, and they are held in place with corrosion-resistant stainless steel Torx® fasteners.

The Zytel sheath with dual attachment panels and black stainless spring steel clip allows eight carry modes and countless variations. Black finish brass Chicago screws allow adjustment of the knife compression fit into the sheath. Equally important, they are used for a multitude of attachment orientations: on webbing, with leg straps, on PFDs, or with a neck cord.

Strong. Simple. Versatile. Extremely corrosion resistant. All bases covered.

Cons: Blade Material, Blade Sharpness
Nice utility knife
I bought this as a gift for an EDC. Out of the box, the weight was fine, grip comfortable and the design offered a variety of uses. The one disappointment was although the straight edge was sharp out of the box, the serrated blade on the opposite side was not. This will definitely need sharpening beforing use. The sheath was quite versatile depending on the users choice of carry although the sheath is somewhat bulky for an EDC.

Cons: Sheath/Scabbard, None
excellent knife
excellent multi purpose knife I use this while kayaking and hiking as a back up. Blade is very thick and purposeful, the knife is rugged as Hell. The sheath could use some work but is good for a lot of abuse, I have molded a kydex sheath for EDC.

Good emergency/diving knife
I bought this knife mostly as alternative diving/emergency knife- with idea to have some multipurpose tool. In general, it fits to purpose. Knife delivered with moderate sharpness- required some sharpening. The edge retention is average- as expectable for AUS8- which has very good corrosion resistance, especially with provided finish. Handle material is durable and feels good in hand. Cons- The tanto blade, located on the working side of the handle, is not suited for any chores- grinding is too thick. Serration is good and sharp, but for my opinion, it will be better to install it on the “tanto” side. If the drop point side will be plain hollow grinded and “mirrored” on handle-this will made this knife a truly multipurpose- and I will give him a higher rating. Seller is good and very efficient
