CRKT Shrill Fixed Blade - Designed by Matthew Lerch #2075

Serves and protects while you're doing the same. The Shrill™ tactical boot knife knows its place on a mission: keeping you and others safe. It's no wonder this fixed blade has the name it does. With a 4.8" dual-edged design it seems to pierce anything in sight.

Matthew Lerch of Sussex, Wisconsin, has been balancing art with mechanics for over 31 years and he's raising the bar once again with the Shrill™. It's a back up knife in the field or a go-to knife in the outdoors, on-duty, and everywhere in-between.

You're asked to work in all conditions. You should expect the same from your knife. That's why the Shrill™ features a versatile dual-edged design with a lightweight 4.8" blade. If it weren't clipped to your boot, you might not even know it's there. But it makes its presence known when there's work to be done.

We made the Micarta handle tough for all conditions, yet stylish as well with a distinctive two-tone design. After all, just because you're battling a 4-alarm or a bad guy in the field doesn't mean you can't look good while doing it.

Just unleash the Shrill™ from its leather sheath attached to your boot or belt. The task at hand doesn't stand a chance.
