[substeps] Place a soft cotton swab at the beginning of the splinter, just above and over the area. (B) These tweezers should be so sharp that they won't pierce skin easily. Close your hands over the splinter and hold them there until the splinter should come out. (C) [substeps] Hold the tweezers parallel to your skin. Insert a thumb into the space between the splinter and skin. (D) Grab the tip of the splinter with a firm hold, and slowly pull it out. [substeps] Sterilize the tweezers before using them.
