Edward 2014 -08 -21 Moriarty , NM Had this knife for 6 years, It's a good knife but I was wondering, Do you sell the Glass breaker for this as an aftermarket part ? Ben 2014 -07 -19 Mesquite , TX What a fantastic knife. There's a short list of things that are ALWAYS in my pockets when I leave my house. My keys, my wallet, my phone and one of my M16-10KZs. This knife has handled every task with ease. Buy a couple. Don't just get one. I promise, you'll love it that much. Thank you, Kit. Thank you, CRKT .
