Sharps and betweens made of hardened steel . Their fine and sleekly-polished tip shape, along with the smooth and non-porous, coated surface, can slide well through all fabrics without bending and breaking – even with the finest needles. The needle head is shaped in such a way that the needles can be effortlessly inserted, even without a thimble. The sharps hand sewing needles are approx. 7 mm longer than the corresponding betweens needles and are used for all conventional sewing work. Many consumers prefer the sharps needles due to their better grip.
