This is the Select Fire Double Action Knife. The blade opens manually with thumb studs or use the firing button for quick automatic action. Each knife comes with a Microtech "key" to turn this automatic into a manual only knife.
This Select Fire knife has an aluminum handle with carbon fiber inserts (front), tip-up pocket clip (back) and colored anodized back spacer up top. The nested locking liner tab is slick and functions solidly. The reverse tanto styled blade is hand ground and satin finished with the Microtech logo on the front face. The blade features an index choil for choking up and notched thumb placement on the spine.
