The Wharncliffe knife blade on my Gerber MP400 multitool came from the factory with the nail nick on the wrong side (inside) of the blade.
I used a Dremel rotary tool with a cutoff disk to cut a nail nick on the outside of the knife blade. That makes the blade easier to grab with a fingernail when opening.
