KNIPEX is the world's leader in plier technology and supplies pliers to professional-grade tool companies such as Snap-on, Matco Tools, and MAC Tools, as well as many others. KNIPEX also supplied pliers to NASA for the Apollo missions. Here, NASA Astronaut Charles Conrad Jr., commander of the Apollo XII lunar landing mission, is photographed during extravehicular activity (EVA) on the Moon's surface. An EVA checklist is on Conrad's left wrist. In Conrad's right hand is what NASA type classified as an "Apollo Lunar Hand Tool", which KNIPEX designed and manufactured for NASA's use on the Moon.

Our line of KNIPEX pliers represents the latest designs from KNIPEX, which are fitted with the new two-piece ergonomic handles for maximum comfort and ease of use.
The ergonomic handles feature a two-piece material construction. The blue material is softer than the red material but not spongy so as to decrease feel or make the pliers clumsy to use. Very slight waists and palm swells are molded into the handles to maximize indexing and comfort. The two-color handle design also makes the tools more patently visible on work surfaces and thus easier to find and harder to leave behind.
Different KNIPEX Plier designs feature different handle shapes to maximize utility for each plier's particular task or tasks. Smaller pliers designed for control feature bulged, pear-shaped designs while larger, gripping pliers feature straighter handle shapes. The subtle shapes of the handles combine with the slight waists and palm swells to form handles that provide supreme control and comfort.
The forwardmost portions of the ergonomic handles feature a flared surface so as to prevent the hand from slipping forward under compression loads.
All KNIPEX pliers are made in Germany to exacting standards, from high-grade tool steel, oil-hardened and tempered, with cutting edges separately induction-hardened to a hardness of approximately 60 HRc and gripping teeth induction-hardened to a hardness of approximately 62 HRc.
Unique to KNIPEX is the patented Cobra Plier design.
The Cobra Plier is designed primarily for use on pipes but is a very handy tool to have in the tool box. Unlike other channel-locking designs, the Cobra Plier features jaw adjustment at the push of a button. There is no need to swing open the Cobra Plier's handles to widen or narrow the jaws as on channel-locking designs, only to find that the adjustment is off and further constriction or enlargement is required, which requires another opening of the handles to adjust the jaws. There is also no inadvertent "adjustment" when the jaws are opened widely. The Cobra Plier is different. Quick, comfortable, and positive tool adjustment on the workpiece is possible with the Cobra design. Simply position the upper jaw to the workpiece, push the button and move the lower jaw. This is an ingeniously simple and elegant design. Furthermore, the Cobra Plier features finer adjustments than channel-locking designs, so it is easier to find an optimum handle width for a particular job.
The unique, unidirectional jaw profile of the Cobra Plier is self-locking on pipes and nuts. There is little to no slipping on the workpiece and less hand force required to obtain a hard bite on fasteners or other working surfaces. The harder the Cobra Plier is turned, the harder the jaws bite into the workpiece.
The Cobra Plier's handles are designed to work in conjunction with the unidirectional jaw profile. As the top handle is tightened to turn a fastener or pipe downward, the bottom jaw hinges upward and bites harder. The harder the pushing force on the handles, the harder the jaws bite into the workpiece. The top handle flanks the bottom handle on both sides for a box-jointed design that resists sideways flex under load and delivers optimal transmission of compression forces. The box-jointed design also prevents pinched hands during use, a problem with channel-locking designs.
The Cobra Plier features gripping surfaces with special hardened teeth for secure gripping of differently shaped workpieces. The unique jaw profile is equally effective on round, flat, square, and hexagonal surfaces.
The serrated tips and bottoms of the jaws are suitable for gripping smaller, irregular surfaces.
The button adjustment on the Cobra Plier is significantly easier to use than other, inferior designs that require the jaws to be opened to be adjusted. The Cobra Plier may be adjusted with the tool on the workpiece.
The Cobra Plier with ergonomic handles is available in both 180mm, 250mm, and 300mm sizes to suit different applications.
As versatile as the other KNIPEX pliers are, the KNIPEX High Leverage Combination Pliers are even more versatile.
Combination Pliers are so called because their jaw profiles permit them to grab and cut equally well.
The High Leverage Combination Pliers are constructed from high-grade tool steel, oil-hardened and tempered, with the cutting edges separately induction-hardened to approximately 60 HRc.
The serrated flats on the tips of the jaws are shaped for grabbing flat surfaces, surfaces that are too large to be handled effectively with needlenose designs. The concave serrated portions are for gripping round or tubular surfaces. And, of course, the cutting surfaces are optimized for cutting. The cutting edges are long for cutting large-diameter wire.
The High Leverage Combination Pliers, with their optimum position of the joint, facilitate easier cutting as well as powerful gripping, bending, and seizing.
While the KNIPEX High Leverage Combination Pliers feature the ergonomic handles, there is more to ergonomics than handle shape and construction. These High Leverage Combination Pliers feature an improved lever action that requires 35% less effort to achieve the same result. Cutting a 2mm thick hard piano wire with a 180mm High Leverage Combination Plier requires an effort of only 318 N (31.8 kg) instead of 486 N (48.6 kg) with a common combination plier of the same length. Combine the improved lever action with the ergonomic handle design and the result is a plier that is eminently easy and comfortable to use.
Unique to KNIPEX is the the patented Plier Wrench, which is a is a multifunctional fastening, gripping, pressing, bending, and holding tool with fast adjustment at the touch of a button. The high lever ratio, parallel jaws, and infinitely variable adjustment guarantee a secure and smooth grip without play on the workpiece. The revolutionary Plier Wrench performs all of the functions of an adjustable wrench, but possesses enough advantages to make adjustable wrenches almost obsolete.
Like adjustable wrenches, the jaws of the Plier Wrench are adjustable to suit different fastener sizes. However, the Plier Wrench has a substantial advantage over a similarly adjustable wrench. An adjustable does not and cannot grip the fastener. The Plier Wrench is different. As the handles are compressed together, they lever closed the Plier Wrench's parallel jaws. Thus, tip spread is minimized. The long handles provide lots of leverage for turning fasteners and the lever ratio for squeezing the jaws together is greater than 10 to 1 for very strong compressive power. As with the Cobra Plier, the top handle on the Plier Wrench flanks the bottom handle on both sides for a box-jointed design that resists sideways flex under load and delivers optimal transmission of compression forces. The box-jointed design also prevents pinched hands during use.
Tip spread is inherent to any open-ended wrench design, whether fixed or adjustable. The tips on an open-ended wrench are not bridged together and thus flower open under load. The result is slippage and rounding of fasteners and work surfaces.
This is why the box end on a combination wrench is so much slimmer than the open end. The open end must be heavily bolstered on its three sides to resist tip spread. The bolsters help but without a bridge to connect the tips, the open end is inherently weak and must remain bulky with little turning power. Though the box end is considerably slimmer than the open end, the box end provides considerably more turning power. (Turning power and leverage are not the same thing. Though the user obtains equal leverage using either side of this combination wrench, he obtains considerably less turning power with the open end than the box end. The open end drives a fastener on only two sides and suffers a tip spread problem with resulting slippage and fastener rounding. The box end drives a fastener on all six sides and suffers very a minimal amount of radial expansion, even under heavy loads.)
This is why open-ended wrenches slip easily under load and round fasteners under heavy loads. The problem is compounded on wrenches with parallel jaws, which by nature must be large enough to fit over a particular fastener size. Even when the wrench is not under load, there is play, however minimal, between the wrench's parallel jaws and the fastener. When the wrench turns the fastener, it must by nature turn the fastener on the fastener's tips rather than its flats. The problem is compounded when the parallel jaws spread open under load. This is why open-ended wrenches tend to slip under load and round fasteners under heavy loads. And the problem is even worse on adjustable wrenches because of the inherent play in the adjustable wrench's jaws.
Many tool companies have ingeniously overcome many of the open-ended wrench's weaknesses. For example, Snap-on Tools offers its patented Flank Drive Plus profile, shown above. This unique design features serrations that grab the fastener under load and prevent wrench slip. In addition to the serrations, the jaws feature a recessed portion into which the points of a fastener will go into under load. The non-recessed portion of the Flank Drive Plus jaw engages the fastener on its flats rather than on its points and drives it on its flats, which prevents fastener rounding under heavy loads. This innovative and brilliant design helps tremendously when only an open-ended design will work on a particular fastener or workpiece. Snap-on offers the Flank Drive Plus concept in both fixed and adjustable designs, and both provide much more turning power thank parallel-jaw designs.
Flank Drive Plus does, however, have a disadvantage. Its serrations are aggressive and leave marks on plated and soft fittings. Fittings such as the brass pneumatic fittings attached to this impact wrench will suffer cosmetic damage when turned with Flank Drive Plus wrenches.
Hence the Plier Wrench. Its smooth parallel jaws avoid damage to plated and soft fittings. The tightening action of the Plier Wrench, a feature that the adjustable does not and cannot have, also minimizes tip spread and fastener rounding.
The Plier Wrench is also easier to use than any adjustable wrench. In this setting, the Plier Wrench may be used to hold flat stock or grip anything of minimal thickness.
Again, the tighter the handles are squeezed together, the tighter the Plier Wrench's jaws clamp together.
Opening the jaws is very simple. Simply let go. Gravity alone will pull the lower handle downward and the jaws will open. Whether open or closed, the jaws always remain parallel, just as with an adjustable wrench.
When the handles hinge open, the jaws also widen.
Adjusting the jaws is very simple. The Plier Wrench adjusts just as the Cobra Plier does. Simply depress the locking button and adjust the jaws to the required size. The Plier Wrench's jaws allow infinitely variable gripping of all widths to the specified maximum size. Furthermore, there is no unintentional adjustment on the Plier Wrench, as there can be with adjustable wrenches. The non-slip joint on the Plier Wrench will not slip unless the locking button is depressed.
The locking button is spring loaded so as to prevent unintentional adjustment.
The Plier Wrench features a great range of adjustment. The 180mm Plier Wrench is suitable for use on fasteners from zero to 35mm/1.375" fasteners.
The 250mm Plier Wrench is suitable for use on fasteners from zero to 46mm/1.75" fasteners. This is a tremendous range of adjustment and gives the Plier Wrench unmatched flexibility.
In addition to the other advantages of the Plier Wrench over an adjustable wrench, there is yet another. The unique action of the Plier Wrench's jaws allows one to tighten or loosen fasteners quickly using the ratchet action. With the Plier Wrench oriented correctly, pushing down on the upper handle both tightens the jaws on the fasteners and simultaneously turns the fastener. Tip spread, a problem common to all open-ended designs, is minimized and damage to the edges of fasteners and other sensitive components is minimized. The tighter a fastener is and the harder to turn it is, the more tightly the Plier Wrench's jaws clamp onto the fastener. To employ the ratchet function, simply lift the upper handle, which in turn opens the jaws and reorients the Plier Wrench on the fastener. The Plier Wrench both tightens and loosens when it needs to.
Like all of our KNIPEX pliers, the Plier Wrench features KNIPEX's proprietary ergonomic handles, which are shaped so as to provide maximum indexing and user comfort. These handles are much more comfortable to use than the handle on an adjustable wrench, even the soft-grip versions of various adjustable wrenches.
The ergonomic handles are eminently comfortable and usable. The ergonomic enhancements work at all adjustment ranges of the Plier Wrench.
The Plier Wrench is available in 180mm and 250mm sizes to suit different applications.
Two more pliers in our KNIPEX line are the Snipe Nose Side Cutting Pliers, in both angled- and straight-jaw profiles.
The Snipe Nose Side Cutting Pliers are forged from a particularly high loadable Vanadium steel, oil-hardened and tempered, with the cutting edges separately induction-hardened to approximately 59 HRc. The slim and precise tips withstand high demands, particularly heavy twisting loads.
The Snipe Nose Side Cutting Plier With Angled Jaws features a 40-degree bend in the jaws for reaching into confined spaces or obtaining a different grab angle on a workpiece. The cutting edges provide cutting ability.
The gripping surface of the angled jaws is serrated for maximum traction on the workpiece.
The long and slender jaws of the Snipe Nose Side Cutting Plier With Angled Jaws provides reach into confined spaces. The rear of the jaws feature a cutting edge for cutting wires.
The Snipe Nose Pliers feature the same pear-shaped handle profile. The handle material is the ergonomic type. The front of the handle is flared so as to prevent the hand from slipping onto the jaws as compression forces increase.
The handles are are flared slightly sideways in a slight palm swell pattern in the rear and a waisted design in the front to provide greater indexing and comfort.
When the hand is squeezed on the handle for a hard hold, the compression forces are spread across the hand and greater comfort is achieved.
The Snipe Nose Pliers are not the spring-loaded type. Many savvy plier users use their pinky to open the handles.
Others simply let gravity pull the lower handle downward to open the jaws.
