CIVIVI Sinisys Frame Lock Knife Twill CF/Steel (3.7" Damascus) C20039-DS1


  • Hand-rubbed Damascus steel clip point blade.
  • Traditional CIVIVI design flipper opener.
  • Carbon fiber twill overlay on G-10 with stainless steel on the lock side.
  • Stainless steel frame lock.
  • Tip-Up steel pocket clip for right-or left-handed users.


Leave it to CIVIVI to come out with another excellent knife that we immediately want to add to our collection. With the Sinisys, they once again combine beautiful design with functionality, and they pull it off using higher-grade materials than other knife brands out there at the same price point. The caged ceramic ball bearing pivot ensures a buttery-smooth opening, and the tough steel promises a happy, long blade life.

Who doesn't love a flipper knife? We know we sure do. Pick up this one while you still can, and then take a look at more flipper collectibles.

Classy for sure !
Vernon M. on Oct 23, 2022

As I noticed this blade did not stay on the shelf long and I can see why! Very comfortable in the hand nice and sharp, work of art on the Damascus. Not too heavy. Size of the blade is perfect! 5 star for sure….

Very 1st Civivi

Bought it the moment i saw it and im so glad i did. The action is so crisp and the blade looks amazing. Very light and an easy pocket carry. Came right out the box razor sharp and for $100, a great buy. Highly recommend this knife.
