if you go to yahoo.com, then click on images, then input a specific description of the sword, yahoo will scour the web for matches. This presumes the thief will advertise it with specific description.
A fellow RN had his unlocked cellphone that hadn't been turned on with any cellphone company stolen out of his car in the hospital parking lot and he got it back because he did keep a seperate record of it's serial and simm numbers, but also the fact that he had it customized with a Miami Dolphin skin with his name on the back, and any attempt to remove the skin would have left severe blemishes. He did the search with yahoo images and input Blackberry etc.... with miami dolphin skin and found it the 2nd day it had been missing and it's now back home with him.
Good luck on your search, I hope they catch the scum.
