I have a Kershaw Leek too. It is a very good “Assisted Opening” knife. Mine has the same handles as the picture. I took off the blade lock slide since it was always getting bumped on. With some Assisted Opening knives, like CRKT models, you have to get the blade open past 30 degrees before the assist starts to work. Those are difficult to operate and, to me they are no better than a manually opening blade.
I confess that I don't always carry it, I only have it when I have pants...
