Specifications

Color Gray

An 8-in-1 hand tool that performs wire stripping, cutting, twisting, crimping and outer-sheath removal, with built-in cable scissors. It includes an AC/DC voltage tester (12–250 V) with dual alarms for hot/neutral detection and accommodates common AWG sizes (18–10) and metric conductors (1.0, 1.5, 2.0, 2.5, 4.0 mm²), plus sheath work on cables up to 25 mm².

First impressions and setup

I tossed the GADO 8‑in‑1 into my service pouch for a week of mixed tasks—swapping out receptacles, trimming fixture leads, tidying a low-voltage control box, and a quick car repair. The idea of one compact tool handling stripping, cutting, crimping, sheath work, and quick voltage checks is compelling. Right away, the footprint and weight felt appropriate for daily carry: compact enough to fit alongside standard pliers, substantial enough to inspire confidence.

The tool’s jaws combine several functions: wire stripping slots sized for common conductors, a set of cable scissors integrated into the head, a crimping section, and features for dividing and opening outer sheathing. The markings lean metric (1.0, 1.5, 2.0, 2.5, 4.0 mm²), though there are references to common AWG sizes. That dual labeling is helpful in theory, but in practice it shaped how and where the tool excelled for me.

Build quality and ergonomics

The construction is reassuringly rigid with tight tolerances where it matters. The cable scissors are the standout: they’re sharp and track true, producing clean, pinch‑free cuts on PVC‑insulated single conductors and typical fixture leads. The handles are comfortable, with enough leverage to get through jacketed cable without wrestling. It’s a deliberately simple mechanism—no ratchet, no complex linkages—so you feel exactly what the blades are doing, which I prefer when stripping insulation.

Fit and finish are solid for the price bracket: even edges, consistent grind on the blades, and legible markings. The compact profile means it drops into a pouch easily and doesn’t snag on other tools.

Stripping performance

On the stripping side, the GADO 8‑in‑1 shines with common household and light commercial sizes—especially 14 AWG and 12 AWG copper, both solid and typical stranded fixture conductors. Using the appropriately sized slot, I got repeatable, clean pulls with minimal rotational effort. The geometry of the blades helps avoid nicks when you’re attentive to conductor size and technique.

Where it gets tricky is at the edges of its range:

  • 18 AWG works, but the clearance is tight and you need a controlled pull.
  • 10 AWG is hit‑or‑miss, particularly with stiffer solid conductors. I could manage with care, but it required a lighter touch and sometimes a second try to avoid chewing at the insulation. You can get there, just don’t expect it to be as easy as 12/14 AWG.
  • There are no dedicated slots for smaller gauges (20–24 AWG). If you dabble in thermostats, sensors, or speaker wire, you’ll want a separate precision stripper. This tool just isn’t set up for those sizes.

The metric sizing bias is noticeable. If you work primarily in AWG, you can still get excellent results, but you’ll want to confirm the slot selection with a quick test pull the first time you strip a particular cable. Once dialed in, the results are clean.

Cable cutting and sheath work

The cable scissors are genuinely good. They make straight, burr‑free cuts on individual conductors and do a neat job finishing pigtails. On jacketed cable, the tool’s features for opening the outer sheath are useful when you don’t want to reach for a dedicated jacket stripper or a utility knife. Within the stated range (up to around 25 mm² equivalent jacket work), I had enough control to slit and peel cleanly without damaging the inner conductors—just remember to keep the cut shallow and let the tool’s edge do the work.

If you routinely cut armoured or braided cable, you’ll still want purpose‑built cutters. But for everyday PVC‑jacketed cable, this is an efficient single‑handed solution.

Crimping and twisting

The crimping station is a pragmatic addition. It’s not a ratcheting tool and doesn’t pretend to be one, so think of it as a field‑friendly crimper for insulated and uninsulated terminals when speed matters more than laboratory‑grade repeatability. Using standard insulated butt and ring terminals in the midrange sizes, I got solid crimps that passed a firm pull test. For production work or critical terminations, I’d still reach for a dedicated ratcheting crimper. As a “one tool, one pocket” companion, though, it earns its keep.

Wire twisting is straightforward: the geometry of the jaws gives you good leverage for aligning and pre‑twisting two conductors before applying a wirenut. It’s not a twist tool in the specialized sense, but it does help keep pigtails tidy and consistent.

Voltage testing: quick checks, not a multimeter

The built‑in 12–250 V AC/DC tester is a convenience feature I used more than I expected. It provides dual alarms—audible and visual—to indicate presence of voltage and differentiate hot/neutral in typical 120 V AC circuits. As a go/no‑go checker before grabbing conductors or swapping a device, it’s handy.

A few caveats from my use:

  • Treat it as a quick screening tool. It’s not a replacement for a multimeter or a properly rated two‑pole tester.
  • Sensitivity can vary with shielding and how you present the probe to the conductor. On one recessed outlet with short leads, it took a second angle to get a confident indication.
  • In 12 V automotive work, it correctly indicated power presence, which is great for basic troubleshooting. But again, verify critical measurements with dedicated instruments when polarity, load, or precise voltage matters.

Keep fresh batteries in it and confirm operation on a known live source before trusting it on an unknown circuit—standard practice, but worth repeating.

Day-to-day usability

What struck me over the week was how often I didn’t need to stop and dig for a different tool. Moving from cutting to stripping to a quick test, then finishing with a crimp, the workflow is efficient. The learning curve is minimal, but there is a rhythm to using a multi‑function head: pause to choose the right slot, set the conductor, strip with a straight pull, and keep your fingers clear when transitioning to the scissors. Once that muscle memory sets in, it’s fast.

The only time I really felt constrained was with fine‑gauge conductors and stiffer 10 AWG solids. In those cases, I swapped to a dedicated precision stripper or heavy‑duty cutter. That’s not a knock—just the reality of any all‑in‑one compromise.

Durability and maintenance

After some purposeful abuse—cutting a handful of copper conductors back‑to‑back, repeated crimp cycles, and sheath work—the edges are still clean and the pivots tight. Wipe the blades after jacket work to keep adhesive residue from building up, and you’ll maintain that crisp cut. There’s nothing exotic to service; a drop of light oil at the pivot occasionally will keep it moving smoothly.

Who it’s for

  • Electricians and techs who want a compact secondary tool for service calls, light installs, and quick diagnostics.
  • DIYers who want to simplify a small kit without buying five separate tools.
  • HVAC and automotive folks who work primarily in midrange gauges and need to make quick, reliable terminations.

Who should look elsewhere: anyone doing high‑volume crimping, frequent work in very small gauges, or heavy stripping of 10 AWG solid and larger. You’ll be happier with dedicated, size‑specific tools in those scenarios.

Value

On balance, the GADO 8‑in‑1 offers strong value. The cable scissors and stripping performance in the 12–18 AWG band carry the experience, the crimper is “good enough” for most field tasks, and the integrated tester saves trips back to the bag. Replacing even three separate tools in light‑duty contexts more than justifies the footprint and price.

Recommendation

I recommend the GADO 8‑in‑1 as a well‑rounded, compact multitool for everyday electrical tasks. It’s at its best with common household and light commercial conductors (12–18 AWG) and routine jobs where cutting, stripping, quick checks, and occasional crimps come up in succession. The built‑in voltage tester is a useful convenience for go/no‑go checks, provided you treat it as a supplement to, not a replacement for, proper test equipment.

If your work leans heavily on smaller‑gauge wiring or you routinely strip a lot of stiff 10 AWG solid, pair this with a dedicated precision stripper or a heavy‑duty cutter. For everything else, it’s a compact time‑saver that earns a spot in the pouch.
