Thanks for your comments, buddies.
Reg E. The handles are wrapped and then locked by two knots. I have experienced with many handle styles and most work well enough. Of course if you keep twitching and pulling, any handle of this type will come loose.
The idea is that the owner can use the cord in an eventual unforeseen need, even though this is unlikely to occour, or substitute it if it gets root or damaged. Eventually, the knife can be re-handled with anything at hand at the moment, eletrical wire, duct tape, etc, or grabbed by the bare tang as it has its corners rounded.
Bryan, I am dedicating myself a lot lately to my Spartan line of working knives and am having a lot of fun with them. The Kiridashis were well received by the public these will also.
Dave, you are not the first to see the piuc and say that but as a matter of fact, it is the temper line. The blade is full flat ground.
