Tulwar hilt repair.

I do not think you will be able to "re-harden" the stuff.

I would take it out, clean the cavity and the tang thoroughly and then use Epoxy Putty: you can get it in aquarium stores. Originally, it is intended to attach rocks, corals etc.

Get the grey variety (there is a green one) and add a little black and red/brown paint (art shops). Squeeze and mix thouroughly for a minute or two, add more pigment to adjust color, fill the cavity, stick the tang in, adjust the angle, tamp the putty in to get rid of air bubbles, remove the excess putty. Leave it alone for 24-48 h. Will hold like a dream.

Just rememver not to linger: epoxy putty hardens fast and then becomes uncomfortable to work with.

Total worktime: 5 minutes flat and you got yourself a battle-ready Tulwar!
