While we accept most engraving requests, we cannot honor all. Some may contain trademarks or other terms that we do not have the right to use.

Engraving requests may contain material that Blade HQ considers inappropriate or simply do not want to place on products. At times this obliges us to decline engraving requests that may otherwise seem unobjectionable. If your engraving request is deemed unacceptable, your order will be canceled and you will be notified via email.

Blade HQ reserves the right to cancel any engraving requests after they have been submitted.

Prices are subject to change without notice.

Cancellations are not possible once the engraving process has begun.

The SOG Trident series features a line and seatbelt cutter in the handle, which allows the operator to cut paracord, fishing line, etc. without having to open the blade or risk puncturing anything in the process. The handle also includes a Digi-Grip variable pattern for coarser grip and notches along the edges in areas that require it. The bayonet style clip is easily switched for right/left hand carry or removed for pouch storage.

SOG's Trident series uses the SOG Assisted Technology (S.A.T.) to quickly propel the blade open with a push of the thumb stud. SOG's patent pending Arc-Actuator helps the Trident to lock up stronger and release easier. On the face of the handle is a built-in safety to lock the blade closed.
