KNIPEX Cobra XS Water Pump Pliers
A pocket-sized 100mm gripping tool — useful specifically for small nuts/pipes in tight spaces, not a substitute for full-size pliers where real leverage is needed.
Quick verdict
Yes, if you want a pocket-size gripping tool for small nuts, fittings and pipes in tight spaces. KNIPEX lists the 100 mm Cobra XS for nuts up to about 24 mm and pipes up to about 28 mm, with the same push-button adjustment as the full-size Cobra. Its serrated jaws can mark finished surfaces, it has little leverage on stuck fasteners, and it isn't insulated for electrical work.
- Best for:
- Small nuts/pipes in tight spaces; pocket/EDC carry.
- Watch out:
- Limited leverage versus full-size pliers on larger fasteners.

Part of our buying guide: Serrated or Smooth Jaws? Choosing Compact Pliers for Small Nuts and Pipes
Our Take
KNIPEX's own product documentation lists the Cobra XS at 100mm overall length, gripping nuts up to roughly 24mm and pipes up to roughly 28mm, with the same self-locking, push-button adjustment mechanism as KNIPEX's full-size Cobra pliers, just scaled down for pocket carry. The real distinction worth knowing before buying is jaw type: Cobra XS uses serrated jaws (strong grip, can mark softer or finished surfaces), while KNIPEX's separate Pliers Wrench XS uses smooth jaws instead (gentler on finish, somewhat less aggressive bite). This is not an insulated or electrical-rated tool — that label belongs to a different KNIPEX product line, and this small size is genuinely about pocket/EDC convenience and small-job gripping, not a replacement for full-size leverage on a stuck or large fastener.
Best For
- Small nuts, fittings, or pipes in tight spaces where a full-size tool doesn't fit
- Pocket/EDC carry for occasional small gripping jobs, not a primary workshop tool
- Buyers who specifically want serrated jaws for maximum grip strength on small fasteners
Skip If
- You need real leverage on a larger or stuck fastener — this small size has limited mechanical advantage compared to full-size pliers
- You're working on a finished/soft surface where serrated jaws would mark it — compare the smooth-jaw Pliers Wrench XS instead
- You need an insulated, electrical-rated tool — this is not that product line
What We Like
- Genuine KNIPEX engineering (self-locking, push-button fine adjustment) scaled down, not a cheaper simplified mechanism
- 100mm size is real pocket/EDC-portable, not just "compact" in name
- Serrated jaws give real grip strength for small, stubborn fasteners
What To Know
- This is not an insulated or electrical-rated tool, despite "Cobra" branding appearing across KNIPEX's broader catalog, including some insulated lines — check the specific product page before relying on it near electrical work
- Serrated jaws can mark soft or finished surfaces — if that matters for your job, the smooth-jaw Pliers Wrench XS is the better-suited KNIPEX tool
- Confirm you're buying the single tool, not a bundle with another KNIPEX product, if you only want this exact pliers
Pros
- Genuine KNIPEX self-locking, push-button adjustment mechanism
- Real pocket-portable size for small gripping jobs
- Strong grip from serrated jaws
Cons
- Limited leverage versus full-size pliers on larger or stuck fasteners
- Serrated jaws can mark soft/finished surfaces
- Not an insulated/electrical-rated tool
Alternatives
- KNIPEX Pliers Wrench XS — Smooth jaws instead of serrated — better if you're working near a finished surface you don't want marked.View on Amazon
- KNIPEX Cobra 125 (87 01 125) — A slightly longer (125mm) Cobra with the same push-button mechanism — the longer handles give a bit more leverage, though its pipe capacity (about 27mm) is no larger than the XS's.View on Amazon
Why PriceDropIQ Selected It
The serrated-versus-smooth-jaw decision (Cobra XS vs. Pliers Wrench XS) is a real, concrete choice buyers in this category actually face — explaining it plainly is more useful than generic "great little tool" praise.
Before You Buy
- Confirm the fastener/pipe sizes you actually work on fall within this model's roughly 24mm nut / 28mm pipe capacity
- Decide whether serrated (stronger grip) or smooth (finish-safe) jaws suit your typical job — compare against the Pliers Wrench XS if unsure
- Don't rely on this as an insulated/electrical-rated tool — check KNIPEX's dedicated insulated line instead if you need that rating
Frequently Asked Questions
Is the Cobra XS insulated for electrical work?
No — this specific model is not an insulated, electrical-rated tool. KNIPEX sells separate insulated product lines; check those specifically if you need a rating for electrical work.
Cobra XS or Pliers Wrench XS — which should I buy?
Cobra XS has serrated jaws for maximum grip strength, which can mark soft or finished surfaces. Pliers Wrench XS uses smooth jaws instead, gentler on finish but with a slightly less aggressive bite. Choose based on whether marking the surface you're gripping is a concern.
