At least the opening is big enough, but too much curve.
The opening between the cutting edges is okay, so at least it will fit a normal male big toenail, but the end is too curved. The curve radius is closer to that of a fingernail than that of a toenail. Ideally they should just be flat with a big enough opening to fit the side parts of a normal male big toenail, where they bend back toward the tow. This is difficult with these, because, although the opening is big enough, the curvature is too much to do this effectively. If you cannot cut that part of the toenail they are useless.
