The Tantilla, by ProTech Knives, is an excellent little OTF knife. Automatic open, manual close, the Tantilla has incredible styling and the very high quality craftmanship that you expect out of a ProTech knife. This OTF looks like the original Cupid knife and works well as an everyday carry knife or for your collection. The action is fast. The lock up is tight. Overall, this out the front knife ranks as one of the better Cali-Legal knives you will find.
