The Injection 3.5 offers sleek good looks, from the tip of its classic drop-point blade to its 3D-machined G-10 handle. The Injection is a collaboration between custom knifemaker Todd Rexford and Kershaw and we think the results are outstanding. Look for high-end custom details like decorative pivot hardware and machined thumbstuds. The G-10 handle has incised cutouts on each side, letting you see through to the stainless steel liners. The G-10 is textured for a secure grip. Even the backspacer offers a custom touch; it's chamfered (cut at an angle) on the back end. Another nice detail is the inset lanyard pin so nothing interrupts the smooth line of the knife. And all of this at a value price.

The 3 1/2-in. blade gives you a little extra length for taking on larger tasks. Built of high-performance 8Cr13MoV, it comes razor-sharp and holds its edge well. The manual opening is smooth and easy. Once open, the blade is secured with a steel locking liner. The pocketclip is reversible for left- or right-handed carry. Want a slightly smaller knife? Check out the Injection 3.0.

The Injection 3.5 is the larger version of the Injection model, and has the same custom features as the smaller version.

Perfect EDC knife!
Jonathan S.
The knife itself is a beautiful design! The blade is the perfect size, and it's very sharp out of the box. The handle is a very nice size as well, and made of a very comfortable material. It's a very good blade, HOWEVER, the screw on the bottom of the handle that holds the handle together was a bit loose when I opened the knife for the first time. It caused a very annoying jiggling noise, and made the handle shift back and forth. EASY fix however as all you have to do is tighten the screw. I love this knife and recommend it to everybody!
