Civivi Hypersonic C22011-1 Folding Knife — Stylish and Reliable EDC Tool

Civivi Hypersonic C22011-1 is a durable and elegant folding knife for everyday carry and outdoor tasks. Designed by Brazilian knife designer Gustavo Thome Cecchini, this model combines thoughtful ergonomics, high-quality materials, and advanced technical solutions. The Hypersonic features smooth blade action thanks to a ceramic ball bearing mechanism, ensuring quick and comfortable one-handed opening.

The blade has a reverse tanto shape and is made from fine-grained 14C28N steel, which contains about 14% chromium and offers good corrosion resistance. The steel hardness is 57-59 HRC, balancing edge retention with resistance to deformation. The blade finish is stonewash with a black coating, which creates a natural aged metal effect, hides signs of use, and reduces metallic glare.

The blade is opened with a flipper, and an additional finger choil prevents the hand from slipping onto the cutting edge. A frame lock ensures reliable blade fixation in the open position. The handle combines stainless steel and non-slip G10 fiberglass inserts, providing a secure grip even in wet conditions. The metal, single-position deep-carry clip allows for discreet pocket carry.

The dimensions and weight characteristics make the Civivi Hypersonic compact and convenient for everyday carry: total knife length — 222 mm, handle length when folded — 128.1 mm, handle thickness — 11 mm, blade thickness — 3 mm, weight — 167.6 g. The review text states a blade length of 93.2 mm, while the specifications list 93.9 mm; both values are present in the model's original documentation.
