What should be done before cutting the toe nail to avoid injury?

The correct approach before cutting a toenail involves soaking the nail in warm water. This practice helps to soften the nails, making them easier to cut and reducing the risk of injury or discomfort. Soaking can also help to prevent nails from splitting or cracking during the trimming process, which can be especially important for thicker toenails that may be more resistant to cutting.

Slightly squeezing the clipper does not adequately prepare the toenail nor ensure safety during cutting. A thicker clipper may be beneficial for sturdier nails but isn't a comprehensive solution to injury prevention. Trimming from the sides instead of the center can lead to ingrown toenails and is typically not recommended as an initial step. Hence, soaking the toenails is the practice that will best prepare the nails for a safe and effective trim.
