I sent this guy a message requesting more info about the knife. I asked him if it was marked Ulster anywhere on the knife and asked if he thought that the knife originally had 2 blades. He informed me that it is tang stamped Schrade Walden NY USA and it is not marked Ulster and that the confusion arouse when he was "researching the knife". He informed me also that the 2 OT was the first Old Timer knife produced in 1959 and he apologized for such a dumb mistake in his ebay ad. He did not address if the knife had been apart or originally had 2 blades. He has changed the wording in his ad slightly but is still asking $499.99.
