I added some navy blue paracord to a Colt Skinny Mini boot knife, doing some lattice lacing on the sheath and West Country whipping around the handle.
I ended up using just under six feet of a single strand of gutted paracord to wrap the knife handle with the West Country whipping, #3458 in 'The Ashley Book of Knots', which is fairly simple with centering your length of cord to start and then tying half knots on each side of the hand as you work from one end to the other.
The textured G10 scales offered enough friction/grip to keep the paracord from sliding off, otherwise I would have first added some silicone tape before going over it with the cord.
For the lacing on the sheath, I used a three foot length of un-gutted paracord, having to run it through the top pair of lacing grommets twice, since there were just five pairs of eyelets instead of six.
The sheath does have a belt clip on the back, which holds to MOLLE straps/pals webbing on a bag/backpack/shoulder strap/vest well enough, but the cord could be used to further secure it in place if carried in that manner.
The rivet holding the belt clip sits up inside the sheath and rubs against the center of the blade when inserting/removing it, but you can't expect too much with lower end of the spectrum imported cutting tools and accessories. A custom kydex sheath would certainly be an improvement, and is on my 'to do' list for working with one of these days...
