Quick Verdict
The Civivi Hypersonic is a well-crafted tactical flipper featuring 14C28N steel with a black stonewashed finish and a reverse tanto blade profile. Designed by Gustavo Cecchini, it offers smooth action via caged ceramic ball bearings and a sturdy frame lock. The steel handle with G10 inlay provides durability and grip, though it adds some weight compared to all-G10 knives. At 3.7 inches, it's a solid EDC size.
What We Like
- 14C28N blade steel with 57-59HRC hardness for good edge retention
- Smooth caged ceramic ball bearing pivot assembly
- Reverse tanto blade shape ideal for tactical use
- Sturdy frame lock mechanism
- Includes ambidextrous deep carry clip
Considerations
- Steel handle adds weight compared to G10 or other lightweight materials
- Black stonewash finish may show wear over time
- Limited to tip-up, right-hand carry only
