The byrd Line's BY17 Cara Cara Rescue and BY19 Meadowlark Rescue both have Sheepfoot, safety shaped 8Cr13Mov stainless steel blades. They're hollow-ground, plain edge, 50/50 or fully serrated for sliding safely under rope, seatbelts or clothing and offer the highest level cutting performance. Ergonomic comfort is equally important as cutting ability in a rescue knife so the fiberglass reinforced nylon handles are Bi-Directionally Textured and have jimping above the Comet Shaped Hole and along the finger choil. Both models have a four-way clip that carries: right/lefthand, tip-up/tip-down. A half-moon of steel removed from the locking lever (called a David Boye Dent) lessens the chance of gripping the knife tightly enough during use to inadvertently unlock the blade. Safe and smart.
