Inspired by the series Demon Slayer, this knife features a striking black and purple blade with blue and purple handles. It includes a metal safety latch to securely lock the blade in place, both when not in use and when deployed. 

Also known as a Balisong or Butterfly knife, this folding pocket knife has two handles that counter-rotate around the tang, concealing the blade within the handles when closed. Butterfly knives are particularly useful in situations where using both hands to open a knife is inconvenient. Please ensure you check your local laws regarding the possession and import of these knives.
