The Sigma Pi Raptor (Epsilon-Nu Series) is simply an incredibly useful everyday carry (EDC) knife and cutter. We’ve designed and hand-crafted this Raptor to be a professional and quality knife suitable for many uses by many people.

The handle and pocket clip is made of Titanium alloy. Being titanium, the handle-lock is very durable and the blade clicks into place very quick and solid.

We’ve included quality bearings on the pivot pin to enhance the user experience. This flipping action with traction is very solid, sounds great, and to be candid, can be addictive to opening. Be careful, the D2 steel blade is very sharp.

Part of our CY6 Lifetime Guarantee includes sharpening. If you ever need your Raptor to be cleaned and sharpened, please contact us and we will give you an RMA number for sharpening. We will send it back at our expense.

We hope you love your new Raptor as much as we have loved hand-crafting it for you in South Carolina!

Each knife is hand-crafted and slight variations in engraving, color, etc. can occur. Please expect shipping to occur within one week of delivery plus delivery time.
