Kershaw Knives

Custom details without the custom price—that's the Injection 3.5 from Kershaw and custom knifemaker Todd Rexford. 

From the tip of its classic drop-point blade to its 3D-machined G10 handle, the Injection offers streamlined good looks. Details like decorative pivot hardware and machined thumbstuds give the Injection a high-end custom look and feel. The G10 handle features six incised cutouts on each side, letting you see through to the stainless steel liners. The G10 is slightly textured for a secure grip. Even the backspacer is cool; 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 price that definitely won't break the bank.

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.
  • 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: Pocket Clip, Overall Quality, Lock Ease of Use, Handle Feel, Handle Material, None
Cons: Weight, Blade Sharpness
I bought the knife to give as a gift. It was a special item, so the price was great for the quality of the knife. I thought the knife was somewhat stiff to deploy, but that could change from use. I saw several reviews, and I too thought the knife was a little heavy in the butt end. It came off centered, and when I did center it, from the pivot screw, it was extremely stiff. I do think it is a good looking knife for the money spent.

Surprising Quality
I was pleasantly surprised at the quality of the Kershaw Injection 3.5 considering the price; I might have expected to pay twice the price for the blade material, finish, and quality, and the fit between the blade, the bearings, and the liners. The liners are interesting; thick, with sturdy lockup. Milling them out would have reduced weight but cost money. The question is, do you accept the trade off? The scales; nicely shaped (I wish many, more expensive knives had this much shaping), but with milled slots that seem to be designed to catch dirt or pocket lint. What is that about? I like the blade; full flat grind, tapering simply to the point, a very nice bead blasted finish. The thumb studs are a little long, but work well for me. The closed retention is good. A plastic spacer instead of open construction with barrel spacers? You have to decide. Again it is a cost issue. It is open enough, and the smooth liners help keep it clean. I think a slightly different set of priorities might have made a nicer knife for the price, but over all, the result is a very good feeling, more than adequately sturdy, knife for every day carry without concern for losing the knife entirely, or losing value by damaging something. That fits my description of an excellent EDC.
