Pen Knives-Novelty Knives - - Items tagged as "Martial arts"
Pen knives are easily concealed so you can take them with you just about anywhere. No one will think that this expensive looking writing instrument actually contains a knife that can be unsheathed very quickly. Nice looking and writes nice too! Keep one in your shirt pocket and keep one in your binder so you'll always be prepared.
These pen knives are refillable and are great to keep around whether you need a letter opener or knife. We make many of these ourselves, so you know they'll last.
