Since the rounded tip does not penetrate the fibers but pushes them to the side, the blunt-tipped embroidery needles are particularly suitable for embroidery with coarser materials such as wool.
The needles with the symmetrically punched eye are completely free of burrs and made of hardened steel.
For threading coarser yarns or wool, the eye of the embroidery needles is accordingly large.
The balanced ratio of length and thickness gives the needles their good usability elasticity.
