Spyderco is known for making solid knives. With the Dog Tag Folder they really went outside the box from their typical designs. The single-sided handle is solid titanium and the overall design is an accurate replica of the shape and size of a military dog tag. The blade is a stainless steel with a stonewashed finish and has the Spyderco trademark round hole for easy opening. The light weight and compact design make it a pretty sweet neck knife. The color we prefer is the Black but it also comes in a Blue/Green.
