The long awaited and very desirable Rotten Design Evo 4.0 T. The first iteration with a tanto blade. It's been a long year of waiting and well worth the wait. This knife has always been perfection to me, and with every version better than the last. This is smaller than the 3.0 and more EDC friendly. The fit & finish impeccable as well as action and dead on centering. John Sorenson is a master of his trade and has continued to strive towards perfection. I can't imagine an avid collector without at least 1 EVO. It's like not having a Strider SMF, Sebenza, XM18 or Arius, shirogoraz, etc. These are the knives that shaped what is today's modern-day tactical collecting and continue to pave the way for the up and coming makers who will shape our hobby and that which will pass down to our children and grand children. I can go on for hours naming the great makers and the models and contributions that have shaped our subculture. Ken Onion, Nick Swan, the contributions of the great Sal Glesser and Spyderco can't forget the controversial Anthony Marfione, Sebastion Borka, and of course Greg Medford. Since 8 years old, I have not left home without a knife flashlight or pen. These are all tools and have made my life easier in many ways. Ad one to your collection if possible. You will be grateful you did. Enjoy and happy collecting!!
