Once the final coat of latex is dry lightly dust the sword with talcum powder. This will remove and residual stickiness and will stop the sword sticking to all and sundry. If you have varnished the sword the talc isn't essential bit I think its still a good idea.
This is an alternative to talc. It doesn't dull the finish like talc tends to but it does make the weapon feel oily all the time.
The final stage is to wrap the hand grip in leather. Don't be tempted to use leatherette as this can be horribly sweaty and clammy. The leather can be either glued or sewn on.
