"TIHK allowed me to scenario-escape in record time ... The escape was after being frisked, and 2 of my other implement plants had been discovered, [but] the TIHK went unnoticed." - Police Officer
“The TIHK key is the smallest but most necessary tool I can think of to keep on me everyday.” - Adam, Security Professional
"I was a little skeptical at first... but after trying it out with several different types of cuffs I am thoroughly impressed! It has worked on everything that I have thrown at it so far. I really like how compact and undetectable it is. I will be purchasing more for all of my friends and family. These are a must for your everyday carry." - Prepared Citizen
