Construction

A butterfly knife is constructed in one of two ways, either a “sandwich construction” or a “channel construction”.

Sandwich Constructed butterfly knife is assembled in layers that are either pinned or screwed together. This method allows the pivot pins to move freely and not bind when adjusted. Upon closure, the blade resides between the layers.

Channel Constructed Butterfly knife Butterfly knife is produced from one piece of material and not layered. Each handle is solid and contains a groove where the blade resides when closed. The groove is created by folding, milling or cast and is considered to be stronger than the sandwich construction.
