CR5410: Flavio Ikoma 5410 Attaboy Folding Knife

Columbia River (CRKT)

Light as a feather, sharp as a talon. Built to handle whatever the day throws at you, the Attaboy puts everything you need from an everyday carry into an ultra-compact folding knife that weighs just 3.5 ounces. Whether on the job or out exploring the backcountry, it won't slow you down.

Incorporating designer Flavio Ikoma's eponymous IKBS ball-bearing pivot system and Ken Onion's Assisted Opening, the Attaboy glides open quickly and smoothly. The 2.7-inch drop-point blade is made of D2 steel for superb edge retention, while Deadbolt, another Ikoma innovation, holds it safely in place when deployed. Despite the small proportions, the knife offers a strong and secure grip that feels natural in the hand. The hybrid front flipper ensures the blade's entire cutting edge is available to use without interference, while the choil lets you choke the blade for maximum control.

Built to spend the whole day at your side, the Attaboy uses a glass-reinforced nylon handle that helps it reach its featherweight status. It measures less than 4 inches long when closed and the deep-carry clip lets it ride low in your pocket, where it comfortably fades into the background until it's needed. Now that's a job well done.

How Assisted Opening Works

It's held securely closed in your pocket, but initiates the deployment, and partway through the rotation, the blade opens at an impressive speed for a simple, powerful, one-handed opening.

How Deadbolt Works

Steel bolts interlock with the blade when it's deployed to yield outrageous strength. A prominent button sits at the pivot point for simple, intuitive disengagement without fingers crossing the path of the blade. It's ingenious, safe, and reliable, what more could you ask for?

About Flavio Ikoma

Some kids dream of being a ballplayer. Flavio wanted to be a knifemaker. In his adolescence, he worked on knives of the Japanese sword variety in his father's shop. He has gone on to learn metallurgy, to work with Ken Onion, and to become a force for innovation. Flavio brought to market the revolutionary IKBS ball bearing pivot system (with Rick Lala), and evolved the classic locking liner with the ILS safety, exclusively available from CRKT in the No Time Off knives.

Sweet little knife
Bought this with a couple of other flippers during a sale. I didn’t know what to expect, but I thought it looked kinda cool, just a little bit different from the rest of my collection, so I bit. Great looking piece, action is snappy and smooth; it’s assisted and fires open nicely, but you can still close it with one hand. Speaking of closing, the push button axis lock is a very cool feature. And SHARP right out of the box - don’t be dissuaded by the D2, it’s still a very decent steel and did a surprisingly fine job chewing through a bunch of boxes that had been piling up. This guy is just a very cool little knife that has quickly become one of my favorites and is definitely going to see a lot of use around the house.

Mine lasted two months
Bought one for Christmas. Used it like a fidget-spinner, probably flipping it 400 times? The spring broke so I took it apart and then contacted CRKT to purchase a new spring, but they don't stock that part. They sent me a brand new replacement, and I'm not gonna use it as a toy so this one should last longer. My blade was loose, too! They never used any locktite or something, so right off the bat it was wobbly. An easy fix, but still. Would choose a different model.

Great design
I always use/carry smaller knives so wanted to get this after seeing the release. The pros: feels great, perfect blade shape, fast opening closing, small pocket clip that surprisingly disappears when you wear it (more manufacturers should try half length or just smaller clips, really dig it). The cons:. Price, not exactly something to beat up with the cost. Overall hope to see renditions of this model.
