The watch case knife is too thick and useless. The screwdrivers are junk and the tips bend or break. The screw drivers wouldn't fit the battery keep screw in two of my watches. I tried to file down the tip of the smallest screw driver so it would fit the screw but it just crumbled. The tweezers quickly magnetized making it very difficult to set the smallest screws. The JAX is OK (why I gave the set 2-stars) so I would just buy it without the rest of this junk.
