The term 'Tie Holder' can refer to three different items: a CLASP, a stickpin, and a tac. A CLASP is a fastening device used to secure two objects together. It usually consists of two interlocking pieces that are connected by a hinge. A stickpin is a small pin with a decorative head that is used to secure a tie or other clothing item in place. A tac is a small metal pin with a sharp point that is used to attach a tie to a shirt or other garment. All three items are used to hold a tie in place and keep it from slipping off.
