Common Questions About the CRKT Attaboy

Designed by Flavio Ikoma, the CRKT Attaboy is a compact EDC powerhouse featuring the robust Deadbolt lock. It combines a high-utility sheepsfoot blade with an assisted opening system that is engineered for easier one-handed closing than traditional assisted folders.

What blade steel and shape does the CRKT Attaboy use?
The CRKT Attaboy features a 2.75 inch D2 tool steel blade with a stonewashed finish. The blade uses a high flat-ground sheepsfoot shape that provides a strong tip and a slight belly, making it highly effective for both precision utility cuts and general slicing tasks.
How does the Deadbolt lock function on the Attaboy?
The Deadbolt lock utilizes steel bolts that engage the blade at the pivot, providing extreme strength and security under pressure. It is operated by a button located at the pivot, which allows you to unlock and fold the knife while keeping your fingers safely out of the blade's path.
Is the CRKT Attaboy an assisted opening knife?
Yes, the CRKT Attaboy series employs an assisted opening mechanism that can be activated using either the flipper tab or the thumb hole. This specific assisted system is designed with a unique bias toward closure, reducing the resistance felt when folding the knife compared to standard assisted designs.
What are the handle materials on the Attaboy?
The Attaboy series uses glass-reinforced nylon (GRN) handles for a lightweight and durable build. To enhance both aesthetics and grip, the handles feature gray GRN onlays and are equipped with a deep-carry pocket clip for a low-profile fit in the pocket.
Who is the designer of the CRKT Attaboy?
The Attaboy was designed by Flavio Ikoma, a prominent knifemaker and inventor of the Deadbolt lock. His design focuses on packing high utility and advanced mechanical safety into a compact, EDC-friendly folder.
