This is the optional LANYARD CAP for the knife handle survival type tube handle.
This cap is aluminum and is sold as a method to create a fully enclosed tube vs using it as a knife handle.
The tube is heavy duty thickness 300 series stainless steel that is knurled on the grip. You can leave this as is or wrap the handle for athestics with thin nylon colored cord. The caps are aluminum.
The knife end cap is sloted with .65" x .20" opening. (300 series stainless steel) Insert a 1.5" to 2" stub tang, pin it in place and drizzle some epoxy through the other end to hold the blade in place. It will never come out. The other end is a solid cap with lanyard loop milled into the end. You can grind this off if you chose. The tube is sealed with included washers that have tested water impervious to 50'.
