The Volcan Knives Amsterdam double action AUTO (Matt Diskin) has a 3-1/4 inch AUS8 stainless drop point blade. The textured G-10 handles provide ample grip for an everyday carry. The highlight of the Amsterdam is its double action auto capability, allowing the user to manually deploy the blade with the thumb hole or use the "sneaky" automatic scale release. There is a switch on the clip side of the handle allowing you to control whether you want it in manual or automatic mode. To automatically deploy the blade, simply slide the switch to automatic mode and slide the front handle scale to quickly deploy your blade.These are Very Impressive & getting Harder & Harder to get....So Don`t miss out !!
