First of all, this beautiful knife only took 4 days to reach me in South Australia. The thin blade is sharp and strong. I find it easier to open with 2 hands. I use both buttons at the same time. Since l am not John Wick, l do not need to open the knife quickly with the thumb disc. I choose to remove the belt clip & replace the end spacer & the two screws. You cannot tell that there was once a clip on the knife. The spacer rattles a bit but the clip no longer irritates your hand. The 2 Carters l have are the highlight of my collection.
