Yep, that's an Old Timer. I've had that longer than I've owned the Blackhawk. Great knife. I found myself needing to remove some small branches in the area of a game camera the other day and that Old Timer did the job as well as any pruners.
The Blackhawk is my hunting backup, which is why I carry the shotshells. Lots of rattlesnakes in the country I hunt in. And those shotshells are the ticket in controlling the snake population around the cabin.
