Almost all braid is pretty slick out of the box.
If you look at my link at the head of this thread. Note how I burn the tag on every knot or termination.
Melting the knot with heat is an binding option but be careful not to weaken it.
Superglue is also an option.
It being slick is a positive attribute. It resists catching dirt and debris…but yes…knots can be challenging.
Under normal use with reels this coating breaks down after a dozen outings. But with tenkara it takes a whole season.
