The Injection 3.5 folder is a Todd Rexford design with milled G-10 scales and a stout liner lock frame. It features custom details that include a decorative pivot, machined countersunk thumb stud and a chamfered backspacer too. The flat ground drop point blade has a bead blast finish and plain cutting edge. The Injection is loaded with all the things you'd want in an everyday carry knife, including a reversible tip-up carry pocket clip.
The Injection 3.5 is the larger version of the Injection model, and has the same custom features as the regular version, the Injection 3.0 knife.
Customer Reviews
1) The action is smooth, and easy to open and close – detent is not absurdly hard.
2) The blade edge seems quite sharp out of the box.
3) The handle is quite comfortable.
4) Clip provides very tight grip, but it's not *too* difficult to clip onto a pocket.
5) The overall appearance of the knife is quite handsome.
6) The size of the knife is quite practical.
CONS:
1) Very noticeable lock rattle when blade is open and wiggled from the tip (to be expected at this price point).
2) Blade is visibly off-center when closed, favoring the top scale (to be expected at this price point).
3) Lockbar could use a bit of dehorning (to be expected at this price point).
4) Thumb studs are insanely sharp on the edges, I’m actually a little worried I would cut myself on them if I moved fast and hard enough on them. I placed heat-shrink rubber tubing on the stud, and that has pretty much addressed that problem.
NEUTRAL:
1) The scales are only very lightly textured, but the flutes help with traction – overall it doesn’t feel *too* slippery in the hand, but I wouldn't mind a little more traction.
1. Locking mechanism is small, and begins to hurt hands after long use.
2. Action is a little sticky and hangs up once in a while, if not for the gloriously huge thumb-stud, opening this knife could be tricky.
3. Be careful how you hold this knife or the pocket clip could create a hotspot in your hand.
4. My Injection 3.5 came to me with a blade that was slightly twisted. As you looked down the edge, you could see that the last third of the blade was bent to the right. But that might just be mine.
All around good knife, will use and love it regardless, and can not beat the price with a stick. 70/100 Would recommend to a money conscious friend.
Weight and grip feels comfortable as well. I'm not afraid of it slipping from my hand.

Good Knife for EDC..
Pros:
Sharp Out of the Box
Beautiful knife
Less than 20 dollars
Very ergonomic
Beautiful Blade
G-10
Great Thumbstud.
Pocket Clip.
Smooth out of box
Full Flat Grind (Personal preference)
Cons:
Comes Tip Up and is not reversable (up to your standards)
Opening and closing for fun hurts thumb a little
A little hard to get to liner lock.
A little on the heavy side.
No jimping.
Pocket clip not deep carry (Personal preference)
Overall a solid knife, worth the price.
predicted. I have yet to find another online retailer that offers the same level of savings, customer satisfaction, and selection as BladeHQ. If you're even contemplating getting this knife, just pull the trigger (or flip the flipper, lol). You definitely won't regret adding this knife to your EDC rotation, knife collection, or even tool box.
----------------------
1) Outstanding functional value for the price!
2) Rock solid comfortable handle, no flex whatsoever with the G-10
3) Not a deep-carry pocket clip, but rides acceptably low where Kershaw has positioned it
4) My first experience with 8Cr13MoV steel, edge came “so-so” out of the box. Was super easy with only few swipes on sharpener for scary sharp edge
5)Great blade tip for precision work
Cons:
----------------------
1) No jimping on rear blade spine for thumb traction, can be slick with wet hands
2) Thumb studs not the most comfortable.
Quick Thoughts:
----------------------
25 days since purchase. I picked up both the 3.0” and 3.5” versions. Honestly you can’t beat the Injection models, they give you a lot of usable knife for such little investment.
My only comment to those considering a purchase, is the thumb studs. They are 100% fine for normal use. However, if you want a knife you can open/close 500 times while watching a movie, you’ll get one heck of a sore thumb. The studs have traction grooves milled into them which can become painful.
