Kershaw Knives

The Injection 3.0 is destined to become you new favorite pocketknife.

It 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-in. blade is the perfect size for so many day-to-day applications. 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 larger knife? Check out the Injection 3.5.
  • Manual - There is no mechanical assist, such as SpeedSafe, used to open the folding knife. It opens the classic, old-school way.
  • Liner Lock - Locks the blade open during use; one side of the knife's steel "liner," the steel plate to which the handle scales are attached, moves into position behind the blade to securely lock it open.
  • Reversible - Pre-drilled holes in the handle enable the user to change either the tip position or the side on which the knife carries.

Pros: Handle Material, Pocket Clip, Lock Ease of Use, Handle Feel, Overall Quality, Ease of Opening, None
Cons: Weight
Quality far exceeds price!
I generally have little interest in budget folders w/8CR13MOV blade steel, but have been interested in the Kershaw Injection 3.0 since it's initial release due to it's simple, elegant design, 3" blade, and especially since it's a collab. with custom knife maker Todd Rexford. When I saw KC had it on sale for $13 I jumped on it. Not only was the F & F impeccable, but the custom touches like the radiused & relieved G10 scales, sculpted thumb studs, and fancy machined pan head pivot screws blew me away since a folder of this quality and features at this price, from a premier production manufacturer like Kershaw, would have been unthinkable several years ago. The real surprise however is that after I put my own 30 degree (inclusive) edge finished w/600 grit DMT stones the humble 8CR steel FFG blade is a cutting/slicing the edge is holding up far better than any previous 8CR or AUS8 blade that has passed through my hands?! Forget that this is a budget blade and just get one...I'm a real steel snob, own far more expensive folders, and yet I can't get myself to EDC another knife (yet) since I bought it!

A great edc
I love my Kershaw injection. I use it at work for cardboard,tape,plastic jugs,mop head material,cleaning agitator beater bars on vacumn cleaners,wire and everything one would use this tool for. The blade width,grind and length are perfect. The handle is contoured and grippy. Blade lock up is solid and came razor sharp. I enjoy using the 3820.
