The Epsilon EKO (Emergency Key Opener) boasts a bottle opener and a letter/box opener edge. Made from domestically sourced 6Al4V titanium construction it's waterjet and the rough blanks are then hand-finished entirely in-house by Prometheus. It has a stonewash finish and contrasted satin chisel ground edge. The edge is sharp enough to cut using the tanto style shape, but the point/tip of the tool is dull and rounded to prevent stabbing pains.
