The Benchmade 530 is based on Benchmade knives Mel Pardue designed Model 350 Knife. The basic looks are the same with the spear point blade and coffin style handle design but, the AXIS lock was incorporated for added performance function of these knives. The overall design was slimmed down for a low profile, low drag carry, and the weight is still incredibly light. So if you liked the Model 350 knife, you’re going to love the Model 530.
