The Razor VX5 is a 3.0″ replaceable blade EDC (everyday carry) folding knife, with features like a ceramic ball bearing pivot, carbon-fiber/G10 handle scales, and a liner lock

Blade system: it uses RazorSafe® replaceable blades (types 300 and 301 are compatible) which allow you to remove and replace blades without tools.

The “VX5-4 Blades” designation refers to the fact that it is shipped with 4 blades (in many configurations). For example, one listing says it “comes equipped with four black-oxide coated blades — including a tanto, two drop-points, and a 50% serrated drop-point.

Another listing says one version includes three plain-edge drop point blades and one 50% serrated drop point blade.

So “VX5-4 Blades” is really shorthand for the VX5 version that comes with 4 replaceable blades.
