While Supplies Last – TIHK No review yet. On order. TIHK is a patent pending handcuff key that utilizes an integrated clip for easy attachment to your clothing so it is ready when needed. Its minimal, low-profile design and low-visibility coating ensure that it can be carried inconspicuously and go undetected when detained. Attach it where you can easily access it when cuffed: jeans belt loop, pants pocket, shirt tag, socks or even on the inside of your pants or underwear waistband. Important Notice The TIHK is to only be used to counter illegal detainment and in accordance with all local, state and federal laws by trained law enforcement, military and security professionals. Improper use by civilians is not endorsed or encouraged. Use of the product is at your own personal risk and discretion.
