Description:

The Interval from Kershaw knives is an original design for the Project ATOM. Like all models included in Project ATOM, the Interval has blunt edges but a sharp and piercing tip. With a larger blade surface, it gives its user plenty of room to work, split, and more! The fixed blade overall resists rust and will last for years to come! Put it to the test and see what makes the Interval so great.

Kershaw has many top of the line knives. If this one doesn’t speak to you, check out more from our selection of
all Kershaw knives!
