1. An applicator device for applying a fluid or pasty product to keratin fibers or to an area of skin, comprising:
an elongate core extending along a longitudinal axis X and having a longitudinal cylindrical shape,
a plurality of spikes distributed over said core, each spike extending from an anchoring end in the core to a free end and being formed in one piece with said core,
wherein the each spike has a first stage extending from the anchoring end to an intermediate section and a second stage extending from the intermediate section to the free end,
wherein the each spike also has a joint face parallel to the longitudinal axis X,
wherein the each spike has:
an intermediate point which is at a middle of an intersection segment between the joint face and the intermediate section, the intermediate point being contained in a first half-disk of radius R1, the first half-disk having a first segment forming a diametral edge of the half-disk, the first segment being parallel to the longitudinal axis X and lying on a first plane, the first plane being parallel and distinct to a radial plane containing the longitudinal axis X, the first half-disk extending from the first segment parallel to the longitudinal axis toward of the radial plane and
an apical point which is at a middle of an intersection segment of the joint face and a section of the free end, the apical point being contained in a second half-disk of radius R2, the second half-disk having a second segment forming a diametral edge of the second half-disk, the second segment being parallel to the longitudinal axis X and lying on a second plane, the second plane being parallel and distinct to the radial plane containing the longitudinal axis X, the second half-disk extending from the second segment parallel to the longitudinal axis toward of the radial plane.
