CJRB Ekko Button Lock Black – 3.25in blade, AR-RPM9

$76.95

(In-Stock)only 1 left

The CJRB Ekko Button Lock Black is an all-black folder with a button lock. Press the button and the blade releases, both to open and to close. It is 4.25in closed with a 3.25in blade.

The steel is AR-RPM9, a powder metallurgy stainless developed for knives at this end of the market. Powder steels have a finer, more even grain than conventionally rolled steel. As a result, AR-RPM9 holds an edge better than the usual budget stainless while still sharpening without a fight. It also handles damp well. So it is a sensible middle ground between cheap steel and a full super steel.

The CJRB Ekko Button Lock Black has a stainless handle finished in black PVD to match the blade. Steel gives it a reassuring weight in the hand. There is a thumb pull, an extended tang and a pocket clip. A black nylon zippered storage case is included in the box.

  • Button lock, one-handed open and close
  • 3.25in (8.26cm) black PVD coated AR-RPM9 stainless blade
  • 4.25in (10.8cm) closed
  • Black PVD coated stainless handle
  • Thumb pull, extended tang and pocket clip
  • Black nylon zippered storage case
  • Supplied boxed

Wipe it dry after wet work and oil the pivot occasionally to keep the button crisp.

In short, this is a well-specified folder that punches above its price.

Not only is this a 5 star review, I am going to throw 5 more ⭐️⭐️⭐️⭐️⭐️ making it a 10 star review ! Scott is such a nice guy. In this show I bought flashlight and then at the end of the show I got picked for the buyers givvy at the end of the show. Scott knew that I really wanted the full size pen made by Olight and he gave me the option to upgrade ( for free ) the prize. He told me to pick a hand and I picked his left and wow it was the one that I wanted and the other hand was a knife with a leather sheath. Now I don’t know if the pen was in his left hand under the table or if he switched it to his left hand because he knew that was what I truly wanted. Regardless I ended up getting what I was wanting so THANK YOU Scott you are awesome !!! During the same show he ordered a knife that he didn’t have that I wanted because it would save me some money if he purchased it instead of me just spending more buying it from the manufacture. Now all I have to do is hope that no one runs me up.

The knives I bought are Extremely nice and the prices of them were Great - The O Clip light is very nice and bright for its size - The mini pen and pencil is smaller than it looks. I have very big hands so I will probably end up giving it to my wife. - The O light i3T - 2 Is a nice color but it is extremely dim for the advances in flashlight technology that other light makers are utilizing. I have a Nebo flashlight about the same size that puts out 3 times the light that the i3T-2 does. - Overall not a bad deal. - Shipping went out same day or early next day - Package arrival time from purchase was remarkable - Thank You
