The CRKT Thunderbolt is a heavy-duty liner locking folder series. It has an InterFrame build with stainless steel liners, one locking, and CRKT's patented LAWKS safety. Ron Lake designed this ergonomic handle with a center swell and grooved areas at the thumb and pommel. The 6061 aluminum scales are anodized charcoal gray with bronze anodized inserts that provide a nice contrast. The pocket clip, like the stainless steel frame is black oxide finished. The dual-grind Tanto-style blade is 8Cr14MoV stainless steel with a non-reflective black oxide coating. Fast one-hand opening is accomplished by a large oval thumb hole.
