CR2081: 2081 RASP Rescue and Special Purpose, Designed by Darrin Sirois


Sometimes, it IS about the size of the dog in the fight.

Retired Sergeant Major and designer Darrin Sirois knew what he was doing when he took a pencil to paper and dreamt up the RASP. Deployment-ready, ridiculously strong, and incredibly sleek, this stout tactical knife is made for the mission.

As a Green Beret, Darrin Sirois of Fayetteville, North Carolina is the kind of guy that expects his knives and tools to take hard abuse...and he designed the RASP tactical knife to accept the challenge head-on. RASP stands for "Rescue and Special Purpose" and it'll do just that and so much more. The blade is at once a workhorse and a head turner—there's simply nothing else quite like it. It's a modified Wharncliffe, dubbed, "Warn Clip," in Darrin's terms, and features a subtle recurve. Though barely detectable just by looking at it, it effectively elongates the cutting surface and gives it a distinctly unique style.

Deployed from its stainless steel handles with an unobtrusive flipper or a right-handed thumb stud, the blade is anchored in place by a burly frame lock. Nearly every last detail of the RASP features a stonewash finish, so it's as sleek as it is powerful and resists rust and wear even in tough conditions.

Where this knife is headed, 'oversized' seems just right.

About the Forged By War Program

In 2013, Ryan Johnson of RMJ Tactical, designer of elite, military, tactical tomahawks, approached CRKT with the news that he had been working with a few combat veterans that had returned from war with varying degrees of post-traumatic stress disorder (PTSD).

To help work through their challenges, they have been designing and forging steel into custom tools. Drawing from their experience earned in combat situations, they have been creating tools they wished they had available to them on the battlefield.

CRKT cares deeply about our returning veterans and they saw a way to give back to the community that created them. In 2016, they launched the Forged By War program.

These are mission ready tools, designed by veterans, with 10% of the CRKT net profits of the program donated to the veterans' charity of choice.

Crazy amount of features
I collect fully custom knives, but i bought 2 of these to give as gift. One went to Darren's (knife desiger) cousin the other went to my father in law who is a career military man so he loved the forged by war program. As for the knives, i was amazed at all the design features in a single knife. The blade is wharncliff, hollow ground, and recurved. The jimping has good placement and texture. The handle has a finger relief cut the makes thumb stud opening instant and also makes for a rock solid grip to provide cutting confidence. The pocket clip has a unique design in look and its placement is also unique in that it serves as the over travel stop. Excellent fit and finish, this a bigger edc knife that can take a beating. This is a great value, for the money you can't get such a well made and designed knife
