The Etfile-Aiguille for the tapestry needles with/Without a point is a flat stainless steel plate with two hooks of different size on each side for different needle sizes.

Since stainless steel makes it extremely stable, even threads and thick wool can also be threaded through a narrow chas. Thus this threader is an essential help in embroidery and knotting. Matter: stainless steel.
