Kershaw Injection 3.5 Liner Lock Knife (3.5" Bead Blast) 3830

This was the knife that started it all. Comfortable grip, not too heavy or too light, and the perfect ergonomics for me. I've never had trouble with it and it still works great. The 8Cr13 steel is easy to sharpen so I've been practicing on this one. Overall a great starting knife if you don't know much about knives.

Honestly I thought that this knife for the price would be pretty bad. But boy was I wrong! The injection is very handy and light. Had it for about a year now and I'm loving it.

It feels more like a $50+ knife for sure. It has a good heft to it. The knife came a little slow to deploy, but once I took it apart, oiled, and then reassembled it, it works like a dream! Very solid lockup, minimal to no blade play, and blade centering was nearly perfect after the reassembly. Easy knife to work on. Best beater knife/starter knife.

I love this economical knife. It's prefect for your every day activities and extra heavy duty thing.

Got one to give to a friend. Came sharp, but wanted go clean up the edge on a sharpening system. It was tricky to remove the thumb studs without damaging them. But, for the price, no complaints.

For the price, this can't really be beat. I used some sandpaper to knock some off the edges of the g-10 scales. It took maybe 10 minutes and made it more comfortable. The blade shape and length allow it to be very useful as an edc knife. I carried it for several months. No complaints. I have a couple of the 3.5 and 3.0 versions.

This is my favorite kershaw import to date. Smooth and solid and the best knife for the price period. Everyone should have one!

This knife has a great looking design. The knife is smooth opening. Good ergonomics. Nice flat blade and as all the Kershaw I've purchased always sharp out of the box. Centering was a little off but was able to fix that with a little pivot adjustment. The biggest selling point is it's price. Definitely a knife worth more than the price.

PROS:
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.

Unbelievable price for this knife. Started carrying everyday. Sharp. Looks nice too.

For and finish is great considering the price. Fair easy to open using thumb stud. Bought it for my wife to try to get her used to something other than a assisted opener. Don’t want her to get spoiled. It’s extremly light weight. Decent edge.

This isn't an epic top-end knife, but you'll be hard pressed to find anything better for the clearance price. It's a tiny tad on the heavy side for EDC, but it's still a great blade for utility. The only reason it loses a star is because the thumb stud opener is seated too close to the liner, making it less easy to flip open then other knives.

First off, this is not a bad knife. Sturdy construction, sharp blade, and looks good. Complaints I would make against it would be;
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.

You just can't say no to this knife at this price! It's the most popular knife of Blade HQ for a reason. Easy to open, locks solid, sharp blade, and feels great in the hand and very well built. Will be buying these as gifts for all my friends!

I love this knife so much I bought a second one. Fits perfectly in my hand and cuts beautifully. I never thought I would say I loved a knife, but I love this knife. It's a shame it's discontinued.

For the price honestly it's awesome. Opens smooth, blade feels great, and it has a nice weight to it. Personally, I don't care for it, I prefer flippers and a bit lighter knives, but this is well worth the price.

I was pleasantly surprised by this knife. Got it for a great deal too! The construction of this knife is solid and beautiful. The action is smooth as butter and the G 10 handles perfectly textured. Steel snobs may not be as big a fan but does the job great for me. Love this knife!

Really nice knife for the low price I got it as a Christmas gift for a friend. A few small things is that out of box the handle is losing color around the pocket clip area, another is that around the pivot you can see machining marks and there are scratches on the blade as well as the thumb studs have some play in them. Other than that is built really well no blade play ,no lock stick. Overall really well built for the 13.99 price

This is my first ever knife and so far it's been amazing. I'm not sure if it's even built for some tasks I've used it for, but I've cut through plastic sealed products, paper, a bit of wood, and I've jabbed it at my tomahawk target practice just to test its durability - it's still good and sharp. However, I don't recommend jabbing it through wood all the time! I'm at least sure it's not made for tactical combat and will get damaged.

Weight and grip feels comfortable as well. I'm not afraid of it slipping from my hand.

Hard to beat this knife for the price! Solid G-10 handle, good grip, even in my large hand. 8cr13mov blade takes a wicked sharp edge in quick fashion and has good edge retention. A slicer, a stabber, and an all around great EDC for less than $15! Better than some of my $50 knives!

Got this Knife a month or so ago and I have to say I really like it, the blade shape is perfect for my everyday needs, keeps a decent edge and I only touch it up at end of day and it is good to go for another day...only flaw I can see is it is not a real deep carry, looking to change that though...
Good Knife for EDC..

I love the value of this knife, and I wasn't expecting much from the knife. Once it came I wasn't much of a fan of it. The design was meh in my eyes, and the main redeeming factor was how smooth the blade was out of the box. However after having it for a little bit, I found myself carrying it around more and just doing some fun things with it, and if you want a cheap knife easy to screw around with then this guy will be your buddy.

The flipper is quite hard

I've used this for a couple of months now and still love it. Perfect blade shape. Easy to sharpen with a ceramic rod and strop. The action still feels good with no slop. I know it's not an expensive knife so I don't hold it to a really high standard, but for an everyday user, you can't go wrong!

Its a great EDC. Small, cheap, and sharp. I bought one for me, and one for a friend.

Overall Rating: 9/10

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.

Solid knife, love the design. Very good price point. Blade HQ awesome to deal with as well

I can't believe this is a $14 knife. The blade centering is pretty good, it's fairly sharp, and it feels pretty good in hand. I will be getting more to edc. The only thing is that the blade is thin.

This was the first knife that I've ordered from BladeHQ. I saw their YouTube video of their top selling knives for 2017 and when they showcased the Injection I immediately loved its design and general aesthetics...It is a Todd Rexford design after all. A budget friendly version of a custom designer's design + an unbelievable price reduction = mind blown. I've had this knife for about a month now and I think it's an excellent budget EDC choice. It feels and performs even better than it looks. The ergonomics on this knife are off the charts...Definitely a great option for a gentleman's EDC. The knife came hair-popping sharp out of the box. The centering is a little off, but that's to be expected on a budget folder. If I'm being nit picky, the liner lock is a tad shallow and won't be very compatible with gloves (although if you're wearing thicker gloves and using this knife, you're probably in need of a more robust knife anyway). I also noticed that there was a minor chip and scratch on the handle of the one I received, but I'm sure this is an extremely rare occurrence. I'm very impressed with BladeHQ's customer service, and the package arrived a day earlier than
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.

Needed a beater knife for the truck and threw $14 at the Kershaw Injection hoping for the best. Couldn't be happier. Smooth opening, good ergonomics and sweet design. I've returned two sub-par $60 knives that didn't match the quality of this knife.

Great knife! I wasn't expecting much as first but when i got it i was blown away. The handles are awesome smoothed g10. Something you never see on a 14 dollar knife. Also, the action was great. Very similar to a rat 1's action. Snappy and quick. The decorated pivot is beatiful and just adds more character to the simple design. 2 suggestions i have is the blade spine be rounded and the finish be stonewashed. However the bead blast makes great cotrast. Overall a great budget knife to throw in a pack or car or even be used as an edc

No where on earth will you find a pocket knife at this price point the reaches the same quality sits nice in your hand opens smooth sharp blade and easy one handed closing

Best for my job for cutting plastic and boxes

Everything you want in a little beater knife

Great edc for the price love it!

She’s inexpensive on the heavy side but, she carry’s well and cuts like a dream. After a little bit of sharpening and tooling around she has been great to have around the homestead for cutting needs.

It has great ergonomics and amazing blade geometry, really thin and ok blade steel when the price is considered. The action on the few I have handled were great. The clip is alsmost perfect, minimal and carries deep enough, I like the way the lanyard attachment is postioned so it isn't and eye sore for those who don't like paracord sculptures on their blades and it is easy to use. My vote for the best gift knife. I especially like the bigger size in my knives.

This is an outstanding value, once taken apart and with the washers polished, this thing was so dang smooth

This is a new favorite of mine. Kershaw did a fantastic job of bringing this Rexford knife to the budget knife market. The ergonomics are excellent, and I really appreciate the chamfered G-10 scales and backspacer. The bead-blasted finish on the blade looks nice until you start using it, and the liner lock bar pushes my blade off center when closed, but not enough to rub the liner. All in all, an excellent, cheap EDC that I'm not worried about beating up. For $14, I can't think of a knife as good as this one. Certainly far better than many other budget knives for two or three times the price. I'll be picking up another soon!

The blade steel isn't a plus or a minus for the price of this knife, and 8cr13mov is very easy to sharpen and use. You aren't going to be carrying this for tactical, hunting, or bushcraft use, so it does not need to be judged compared to those types of knives. This is a great edc folder which is a little heavy, but not too heavy that it's unattractive. This knife is well suited for small edc tasks, and I would recommend this to anyone who wishes to buy a great knife with good design and not feel bad about breaking the bank or possibly losing it.

This knife is great. It is outstanding in just about every category. Just a little locktight on the pivot and this blade is perfect.

Pros:
----------------------
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.

Got it on sale and I'm happy to report that it's a rather nice knife. Good solid build quality, thick liners, great action running on washers, pretty easy to deploy. If I'm nit picking I'd say the thumb studs could use some more texturing and it's a little heavy. The thumbstuds also get in the way of sharpening the blade. It did not come razor sharp so I touched it up with a 1000 grit stone and got it hair popping sharp, it felt like the steel is a little soft but only time and use will tell. Overall it seems well made and has a nice action so I'm having fun flipping it.
