What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, the Klein 11063W "Katapult" is the most consistently praised wire stripper in this pool. On r/Tools and r/electricians, longtime users describe it as the stripper they keep coming back to after trying others, with multiple threads calling out its gauge-specific stripping holes for producing cleaner cuts than squeeze-style automatics regardless of insulation type. A r/Tools comparison thread specifically credits the Klein over a comparable Irwin for its dual-adjustment design and dedicated cutting blade.
What reviewers liked
- High-trust subreddit consensus (r/Tools, r/electricians) treats it as a long-term keeper
- Gauge-specific stripping holes produce cleaner cuts than squeeze-style automatics on tough insulation
- 4.8-star average across roughly 11,000 Amazon reviews — very high engagement
- Built-in cutter is well-regarded in community threads
Where it falls short
- Reviewers on r/electricians note it is bulkier than traditional Klein strippers
- Wide jaw opening for MC cable is a dealbreaker for some users
- Katapult action has a learning curve called out in multiple YouTube demos
- Not ideal for very fine-gauge electronics wire below the supported range

Verified-purchase reviews surfaced on retailer listings echo the durability story, and thespruce.com (verified-tier) places Klein wire strippers prominently in its best-of coverage. Reviewers do note the tool is bulkier than traditional Klein strippers and that the wide jaw opening required for MC cable isn't for everyone. Across mainstream YouTube demos, the consensus is that the Katapult action is fast once you adapt to it but has a learning curve.
The trust-weighted picture is unusually clean: a verified source, multiple high-trust specialist-community threads, and very high retailer engagement all point the same direction.
- Wire Stripper and Cutter cuts and strips 8-20 AWG solid and 10-22 AWG stranded wire with ease
- Compound action stripping
- grip and strip via single-action squeezing motion
- Precision machined stripping holes easily remove insulation without damaging the wire
- Removes up to 1-Inch (25 mm) in length of the insulation layer (jacket layer) in a single step
- Tension loaded wire-grip gently holds the cable while retaining cable geometry
- Cast alloy chassis with heavy-duty Ecoat finish for corrosion resistance and durability
The Klein is much more recent with 2 adjustments and has a (probably Klein-exclusive) cutting blade. I own the Irwin and have been underwhelmed ...
It has blades with holes specific to each supported gauge. The upside is that you get a perfect cut, much better than the other one, regardless ...
