CIVIVI Synergy4 — Design and Use

Jim O’Young’s Synergy4 expands the Synergy design into a larger folding format. Its sculpted handle and long blade carry the family’s flowing lines through a full-size everyday knife, with a flipper as the opening point.

The nested liner lock sits within the handle, and ceramic bearings support the pivot. Trailing-point and tanto configurations provide different edge and tip geometries, so the exact blade style below matters. The dimensions also distinguish the Synergy4 from the smaller Synergy3 and Mini Synergy designs.

The C21018B-1 blade is made from Nitro-V. Its finish is black. The handle uses G10.
