High Performance from World Class Design
I designed my Venturi VIII Series™ Balisongs with high precision sandwich-style construction and radiused, domed tops for custom-made high-performance Balis that are completely faithful to the tradition of the original Balisong knife.

Every Venturi Series™ is a custom knife with a 4.25-inch blade and Titanium frames with a total weight of only 4 to 4.5 ounces. All Venturi Series™ blades are flat ground for optimal blade-to-handle weight ratios and the highest flipping speed. I mount them on highly durable, hardened stainless steel pivots with prosphorous-bronze washers and guarantee that they last. I’ve just completed the latest updates to my Venturi Series™ line and have tested it to ensure that these knives keep their reputation as the best you can buy. For those who learn how to handle them, Venturi Series™ are as fast as automatics and probably the ultimate hideout self-defense knife. Combined with perfect sandwich-style construction, my Venturi Series™ Butterfly knife is the one that famed self-defense expert Mike Janich called the best Balisong knife he has ever used. Martial Artist around the world use Darrel Ralph Knives.

World Class Design
The first knife I ever made was a Balisong and I am still in love with this knife. I draw inspiration from that encounter and I work to add to it everything that I’ve learned from designing and building tactical folders over my career. There is no faster, better built custom Balisong than the Venturi Series™.

Radiused and Carved Rails
Rounding and doming the rails on the Venturi Series™ was my original design to create the finest Balisong in the world. With this innovation, your Venturi Series™ becomes a working part of your hand. You don’t work around any high points to flip your Venturi Series™, because it doesn’t have any. You can develop high speed more quickly with the Venturi Series™ because it is the ultimate high-performance Bali. And the Venturi Series™ does not slip out of your hand.

SURE GRIP II™ System
I guarantee the best grip and manipulation with the Venturi Series™ by adding my Sure GRIP II™ grippers inside the rails. They make your Venturi Series™ grip back with the strength and skill of a sparring partner. The fastest, surest manipulation is the primary goal of the Venturi Series™ Balisong.

Guaranteed Durability
Never worry again about pivot wear. My Venturi Series™ pivots and studs are made from hardened stainless steel that I guarantee for life.
