Thanks Ferguson
This same dealer had a very unusual Katar type sword.Very Old it had about a 36 inch blade that was very thin and a hand guard and wrist atachment.
To put it on you reached into the handguard and grab a rod that runs from side to side then you hook the back of the gurd across your wrist about 6 inches back across your forearm.The blade then extends from above your knuckles atop of the back of your hand. it is very old. Have you folks ever seen one of these type blades?
Here is a link to one I found on the web
