Those look goodman. I have never made a kiridashi, but i have done a few cord wraps, and i always had to gut the cord to get it to lay flat and even. I am not sure how it would affect the GITD cord, but i soak mine with super thin CA glue and they are great. Very durable and super grippy.
That glow in the dark para cord would make a really cool under lay wrap on a handle! What steel did you use for them? I would like to have a kiridashi for at work.
I used 154 cm and haven't decided exactly how they will be wrapped heh. it will be a lot of experimenting.
