    Small, but I needed small
  

*by C***O on Reviewed in the United States on February 6, 2024*

This is exactly what I needed for my toolbox. I didn't realize that I needed it until my others were too large. This is simple, straight, and built like a tank. Plus, I can use it as a throwing star during the zombie apocalypse.
