This model has us as knife junkies, very impressed. If you're a true fan of burl wood, this is a unique knife as there aren't too many gut-hook blade models on the market that include burl wood scales. You're sure to be pleased with the quality of this fine framelock knife. It features a spring-assisted operation. When you start to manually push the flipper tab portion of the blade, the spring assist starts to kick in after a certain point for a smooth opening operation.
