The Clever Design of the KNIPEX Pliers Wrench that Most Brands Have Mimicked
Written by Luis Montes Updated On May 13, 2025
Although there are countless brands and models of pliers wrenches, the name KNIPEX always appears in reviews and forums as a reference to originality, clever design, and high quality.
Since most tool companies have copied the KNIPEX pliers wrench design, you can get a similar product at a fraction of the price.
However, at Fortis, we don’t want any tools, but the best ones for the blue-collar community and DIYers, should this last group be willing to invest a bit more to purchase the best tools.
So why get the best if I can do the same for less? Think about it this way: which one of the options below would you give to your kid as a present? Or which would you have preferred as a kid? You can play with both, but it ain’t the same, is it? Now that you’ve grown up, why not get the best “toys”?

Let’s review why you should get a KNIPEX pliers wrench, the 1:10 leverage ratio, and how the tool compares to some popular competitors.
Why Should You Get a Pliers Wrench?

The pliers wrench is a great EDC multi-purpose tool that combines an adjustable wrench and tongue-and-groove pliers. It also replaces full sets of inch and metric open-end wrenches.
The pliers wrench saves you from carrying a dozen wrenches, making it ideal for hydraulic work. With a few exceptions, this tool can do every fitting.
The pliers wrench doesn’t fit 100% into the adjustable wrench or tongue-and-groove pliers categories, but it knocks it out of the park in every category.
It is faster to adjust and won’t get jammed. Its mechanism (which we’ll break down in the next section) generates much more clamping force, making slippage between the jaws and the fasteners virtually impossible; thus, it won’t round off the material.
Besides multiplying the clamping force, the jaws of the pliers wrench remain parallel, so it’s like having a little vise with you. You can do sheet metal, straighten bent nails, or safely grind small parts, such as keyways, to name a few applications.
The KNIPEX Pliers Wrench 10:1 Leverage Ratio

The signature feature of the KNIPEX pliers wrench is the ability to multiply the squeezing force applied to the handles. KNIPEX calls it the 10:1 ratio and relies on a simple mechanical principle. Check the following picture:
The force #1 you apply to the handle generates a torque around the adjustment position button, which is the pivot point. The same torque value divided by a shorter lever arm #2 generates a force #2 (10x greater than force #1) at the lever in the head of the pliers.
Force #1 x LEVER ARM #1 = Torque → FORCE #2 = Torque / lever arm #2
The multiplied clamping force of the KNIPEX pliers wrench enables it to develop a self-locking ability, similar to that of the KNIPEX Cobra pliers, but without relying on angled teeth.
Just like with the Cobra pliers, pushing the upper handle will make the pliers wrench bite further without squeezing the lower handle.
The self-locking feature allows you to focus on breaking loose stuff instead of wasting energy to prevent the pliers from slipping and rotating. It ensures the operator’s safety and makes work more efficient.

| The Knipex set has put all my Crescent and adjustable wrenches in the deep corners of my garage. I use them more often than I did the adjustables - for general-purpose wrenching, flattening and bending metal, etc. I like them as a tool, and they've been far handier than I expected, which is why I own three Knipex sizes and made the decision to get one for spare or travel. | ||

| I’m a DIYer and a value buyer. But I’ve been sufficiently impressed by the real Knipex stuff I’ve bought, and sufficiently disappointed by the knockoffs, that I’m not sure there’s enough savings to tempt me, even for a very good imitation. | ||

| One of these will replace a whole set of the usual spanners and is far better than any adjustable or novelty spanner I've ever used. It has infinite variability, parallel jaws, clamps like a vice and can be used 'ratchet' style, so it's quick to use and you'll never burr the edges on fasteners again. Looking now, I see that there are loads of videos on YouTube about them, all of which completely passed me by - wish I'd had them years ago. The only thing they can't replace is sockets, but you can use them in conjunction with a socket and square-ended extender. Anyway, can't recommend it too highly. | ||

| I have a pair, they’re nowhere near as good as the Knipex. The metal is soft. They change dimension too easily. You need to push a button to open the jaws’ width, but they’ll get smaller if you bump them. | ||
| Website: Reddit | Member: cuttingedgegeek | |
| The jaws on mine are super soft and deform easily. Hopefully just a bad batch, but I don't know. | ||
| Website: Reddit | Member: lavardera | |
| I have these, and the Knipex. The Irwin's cam is poorly sized, and the jaw motion is too small for the handle motion. The jaws are awkwardly large and hard to get into a nut or bolt head. It's nice that they're making one, but hopefully their second revision will be improved. In the meantime, treat yourself to a Knipex if you can afford it. Otherwise, $15, maybe $20 for the Irwin, any more wait and save for the Knipex. | ||

| I have all of the Knipex pliers wrenches and love them, but I did get the 2 sizes of the Irwins to keep in the truck for random or unplanned use. If I lose the Irwins, it won't hurt as badly. They have been useful. They are not in the same class as Knipex, but they are fine for the price. | ||

| The reversible jaw is a near useless gimmick, and I wouldn't put any weight/value into it. If you need V-jaws, then you'll want a set of Cobras or a decent copycat instead of just a plier wrench anyway. 12" Cobras + 10" pliers wrench gets me by on most things, and I'd be after a bigger set of XL Cobras as my next tool rather than another pliers wrench, but that's just me. | ||
| Website: Reddit | Member: DeadlyTacoFarts | |
| I use these and the Knipex plier wrench often. IMO, you're better off having a set of the Knipex PW and some Cobras (or solid copies of them). You know, 2 items that do their jobs spectacularly instead of 1 that's just OK at everything. That being said, the Klein works fine with the flat jaw, but the toothed jaw is gimmicky, and its grip is only so-so. One big difference I've realized, though, is that the handles of both my Klein pairs have flex to them and seem weak and bendy when applying higher forces. My Knipex handles feel solid AF in comparison. | ||
| Website: Reddit | Member: Sabertooth_Monocles | |
| I had those Kleins. Hated them. There is very little variability in each position. It's super frustrating to get them set just right for the job at hand. | ||
| Website: The Garage Journal | Member: Renegade1LI | |
| Just received 2 pairs today, they feel nice, I like the release mechanism better than Knipex. The reversible jaw, I think, will be the weak point. I hope they sell extras. These will get abused in the next few days, giving them to a fitter crew doing some small pipe, up to 2". I want them to beat them up like their channellocks, don't hold back, and we'll see what's left. | ||

| The jaws of the Knipex are perfectly flat, where the Icon pair allows a tiny bit of daylight through. I've used my Knipex pair to flatten metal a few times, which is a rare but really useful thing. Since this is a road-pair, I don't really care - it works fine on the fasteners I tried, and that's what it will be used for exclusively. I agree with the folks who say the "Designed by Icon" on the package is ridiculous (it's on most or all of Icon stuff) and wish they'd taken a couple of options to be less... Knipexy... in the overall design, but ultimately it isn't a big deal for me. | ||
| Website: Reddit | Member: r/harborfreight | |
| Used the Icon Pliers wrench now for a couple of days in the field, and honestly, I'm underwhelmed. The quality compared to Knipex is just not the same. It's a lot sloppier, doesn't adjust as easily, and the finger grip areas on the Knipex, along with the body texture, make the Knipex much nicer to use. | ||
| Website: Reddit | Member: M635_Guy | |
| I have a fair number of Knipex pliers - they're great. They're pricey, but they're great, and their customer service seems to be pretty great. But other than a couple of millimeters less opening and being a bit more rudimentary in design (like the Knipex 1st-gen pliers wrench essentially), I don't find the Icon at any real disadvantage to my Knipex 250mm pair. | ||
| Website: Reddit | Member: JoshvJericho | |
| I swear, people need to learn to temper expectations. Is the Icon pliers wrench good? Yes. Is the Knipex PW better? Also yes. However, the Icon costs half the price if full priced, but only newbies or someone in a hurry pays full price at HF. As long as I'm getting at least 50% of the same efficacy as Knipex with the Icons, it's a good buy. | ||
| Website: Reddit | Member: Acceptable_Canuck | |
| I haven’t tried the Knipex, but I’d agree underwhelmed is a good word for the Icons. For a cheaper option, I prefer the Irwins. | ||

| Yes, they are goofy and ugly, hahaha, but as long as they get the job done, oh well. | ||
| Website: Reddit | Member: Jataka | |
| The jaws have a much wider opening/footprint than any other pliers wrenches of a similar handle length. The mechanism is akin to Knipex, obvi, but is not on the same level as Gedore, Knipex, Fujiya, ICON, etc. | ||

| My biggest concern is that this spring-loaded pin mechanism on the Wiha pliers doesn’t look like it would be easily serviced if the spring broke or wore out. That’s in comparison to the Knipex tool, where the mechanism can be easily replaced by removing a screw. | ||
| Website: www.toolguy.com | ||
| I must admit, button-free Pliers Wrench operation sounds appealing. But on the other hand, my Knipex Pliers Wrenches have never let me down. They were all pricey, and continue to be pricey, but they’re well-built and top-quality tools. | ||

| I have a set of Lindström Supreme pliers that I have had for about 25 years now. They are very good. At that time, Lindström was made in Sweden, and I think they still are. I also have a couple of Knipex and Wiha pliers, and they are good too. | ||
In a Nutshell
Not having a pliers wrench nowadays is like still using a rotary dial phone to make a call. Just like there are better ways to communicate, the KNIPEX pliers wrench is a much better way to work on fasteners without rounding them off than using an adjustable wrench or a tongue and groove pliers.
Although there are many pliers wrenches on the market, KNIPEX is the standard, as shown by the testimonials from the previous section.
Stop purchasing knockoff tools, get the real “toys,” get KNIPEX.
