Back off! The Papa Delta is small, but can be ready in an instant when you need it.


There are a lot of reasons to carry a knife every day. From regular daily cutting tasks to pocket jewelry, to self-defense, and more. What an individual decides to carry is a deeply personal choice with many factors to consider, such as local laws, permissiveness of the area, what clothing is going to be worn, etc.

Leo Espinoza designed the Papa Delta with input from a retired undercover police/intelligence officer. So the thought process is specifically for people who need to be able to wear the knife completely undetected. That is why it’s thin, skeletonized, and low profile in every aspect.

The “incomplete” finger hole is purposely not closed off. The reason is so that the knife can be let go of more easily than a normal karambit where the ring is specifically there to retain the knife. It’s also double-edged with a fuller to make it as useful as possible for defensive purposes.
