I have never been a fan of framelocks. I liked the Axis lock and the Compression lock and CBB lock more. But I decided to try a Spyderco advocate...and it was fantastic. I was won over! I like bigger blades...and I saw the 0452CF by ZT so I ordered it. When it arrived it needed sharpening! So I hit the sharpmaker and then started to carry and use it. I can't believe what I have been missing! Light weight, epic action, great fit and finish (except the edge). Holy cow what a great knife! I do not like most of ZT's other offerings...huge, heavy...ugly to me. But the 0452CF is the freaking bomb! I am a happy camper now! Sinkevich for the win! Does anyone else here like this knife? I can't believe it is so good!
