The 2 I have are in the tool kit shipped in the box with a 4" 25-5 on the 31st day of 1986 and the other with a Model of 1988 625-2 that shipped on the 103rd day of 1989.These tool kits have the straight knurlned end cleaning rod.

On one side of the 2 bladed tool it says "Smith & Wesson Since 1852" stamped into the metal and on the other side it has the S&W logo and "Sight Adjustment Only" stamped into the metal.

The key ring holes on both my samples are the same size.

I am not the original owner of the guns.
