I'm sure blood would stain the lighter colors.
The darker colors like OD green, woodland camo, multi-cam, and black would most likely wash out clean and never show a stain.
If I was going to put a functional lanyard on a working knife I'd use OD or black and not worry about it.
There's a reason I use black or OD on my coyote drags.
I can make lanyards that would loop into the hole in the handle, IF the hole is big enough for a doubled cord to fit through. They are so simple to make I could do a 5-pack that would last a long time for CHEAP.
