I really like a good dual action knife. There is something appealing to me about a knife that looks and feels like a manual folder but can be used as an automatic knife if needs be. The Harkins ATAC dual action automatic knife by ProTech is the best one I have ever seen. Lightweight, it feels just like the manual version of the same knife. The speed of the opening mechanism is fast. Just like you would expect from a ProTech automatic knife. And the look is top notch. With the carbon fiber scales (there are two on the handle, an upper and a lower) this knife looks like it belongs in the boardroom. You lightly press the upper scale and the blade snaps out. This is a definite 10 out of 10 for me. Review by T
