The Matthew Lerch designed Shrill fixed blade is a tactical boot knife to aid in protecting. It has a symmetric design with a 4.8" dual-edged dagger blade and full-tang handle with layered Micarta scales. CRKT kept the Shrill's weight down to enable comfort in everyday combat attire, and it includes a leather sheath for attachment to your boot or belt.
I couldn't find a lot of reliable reviews on this knife so I rolled the dice and bought it, I was not disappointed. I have thin layered boots, but that doesn't stop the clip from hanging on tight, allowing me to pull the knife out with ease. I hope I never have to use one of these for self-defense, but just in case, it's not leaving my boot! My one complaint about this knife would be that it's a bit tricky to get a firm and reliable grip on the handle. Otherwise, solid build and design. UPDATE: It's been a few months, and I've had to retire the knife far earlier than I expected. The tip of the blade is bent somehow, causing it to fail to enter its sheath properly.
