Klein Tools has two new pliers wrenches out, and the thing that sets them apart is the jaws. Unlike the Knipex-style smooth jaws most of this category uses, the new D5327 (7-inch, $28) and D53210 (10-inch, $33) come with knurled, grooved jaws. Both are in stock at Amazon now.
Pliers wrenches are adjustable-jaw tools meant to replace a whole set of wrenches and slip-joint pliers. Squeeze the handles and the parallel jaws flatten out on a nut or fitting. Push-button adjustment sets the width. Klein’s version adds slim heads for tight spaces, laser-etched size markings, and that knurled gripping surface.
Specs and Pricing
| Model | Length | Jaws | Price |
|---|---|---|---|
| D5327 | 7″ | Knurled | $27.98 at Amazon |
| D53210 | 10″ | Knurled | $32.98 at Amazon |
Klein already sells a smooth-jaw line in the same sizes (D5317 and D53110, around $25 and $30). So the knurled version sits a couple dollars above its smooth-jaw sibling at each size. The company’s pitch for the teeth is extra grip on rounded or damaged fasteners, where a smooth parallel jaw would slip.
The Trade-off in the Jaws
Smooth jaws exist for a reason. Knipex built the whole category on them because flat, untextured faces don’t chew up chrome nuts, trim pieces, or plated fittings. Grooved jaws grip harder but leave marks. Milwaukee’s toothed 10″ and 12″ pliers wrenches made the same bet Klein is making now: grip over finish-safety.
If you work on plumbing rough-ins, rusted hardware, or anything you plan to replace anyway, the teeth are a plus. If your work involves finished fasteners, trim rings, or anything a customer sees, Klein’s own smooth-jaw models are probably the better pick from the same shelf.
How It Fits the Market
This is Klein’s second pass at the category. Earlier Klein pliers wrenches used reversible double-sided jaws, one face smooth and one knurled, which covered both use cases in a single tool. The new D53xx line splits them into separate models instead.
Milwaukee launched its first pliers wrenches in February with smooth parallel jaws across five sizes. Tekton, Channellock, Irwin, and Harbor Freight’s Icon all sell versions now. The category has grown fast enough that brands are competing on jaw texture, adjustment feel, and head profile rather than the basic concept.
At $28 and $33, Klein is pricing under Knipex, whose 7″ and 10″ pliers wrenches typically run $40 to $55. For an electrician who already trusts the Klein name and wants one tool that adjusts across a range of nut sizes, the entry cost is low.
Both sizes are available now at Amazon (7-inch) with the 10-inch at $32.98.
