What an incredible coincidence -- you advised use of toothbrush and paste, which is precisely what I stumbled upon myself, just yesterday. Great minds thinking alike, etc.
Actually dug out a lot of the broken resin, then heated the back of the blade red-hot over a fire in my ashtray, jammed the back of the blade into the remaining resin and -- viola! It seated itself!
To be safe, I did line the new seal with epoxy, let it cure for a day, then drilled it down far enough so the hilt could fit onto the scabbard (which is sparkling cleaning and brand spanking new, thanks to the ol' toothbrush - n - silver cream polish treatment!)
Result? The little khanjar shines, is functional and beautiful. Even though the seller offered to refund our purchase price, I chose to keep it and repair it. Now my wife no longer gives me The Look....you know the one.
Only problem now is, where to hang it? (Please see pics attached)
* Above the big Scimitar?
* Above the Koummyas?
* Or leave it in its current spot?
* Right below the flag from my father's coffin (WWII Vet)?
And HOW to hang it on a wall without damaging the khanjar or the belt? Hmmmm.... Any ideas greatly appreciated.
