Hobnail (3.5e Equipment)
From D&D Wiki
The hobnail is an iron bar with a curved and flattened point on one tip. The other end is tapered to a point. The shaft is jagged and roughened for scraping motions against bare flesh. The hobnail is forged by some tribes of hobgoblins for use by infiltrators.
The curved end of the hobnail can be use to pry, providing a +2 circumstance bonus to Strength checks made to open doors and containers.
