CIVIVI Ki-V FAQ

Designed by Ostap Hel, the CIVIVI Ki-V is a compact utility tool featuring a non-locking detent joint and a 5th-pocket-friendly profile. This series excels at precision scoring and light everyday carry tasks thanks to its distinctive Kiridashi-inspired blade geometry.

Does the CIVIVI Ki-V have a locking blade?
No, the Ki-V series utilizes a double detent slipjoint mechanism rather than a mechanical lock. This non-locking design uses internal detents to hold the blade in the open or closed positions, which can be advantageous in areas with restrictive local knife laws.
What is the blade shape of the Ki-V?
The Ki-V features a Wharncliffe or Kiridashi-style blade with a straight cutting edge. This geometry is specifically optimized for utility tasks, as the tip remains stable during scoring or piercing cuts.
Is the CIVIVI Ki-V small enough for a 5th pocket?
Yes, the Ki-V is an excellent candidate for 5th pocket carry due to its 1.55-inch blade and compact handle. It features a deep-carry pocket clip that allows it to sit low and discreetly in small watch pockets or shallow clothing pockets.
What steel is used in the Ki-V series?
The Ki-V series uses 9Cr series stainless steel, which provides performance characteristics roughly comparable to 440C. It offers a practical balance of corrosion resistance and ease of sharpening for a small utility folder.
How do you open the Ki-V?
The CIVIVI Ki-V is designed as a front flipper that can be opened one-handed using the thumb to catch the jumping on the blade tang. While it can be flipped quickly with practice, it is equally suited for a controlled slow-roll opening.
