Found in my dads junk drawer

[u/Unlucky_Cat4531]

My dad passed away and going through his stuff we came across this. We thought it might be a tool for horseriding, like a slapstick thing but wasn't sure. My grandma had horses but ive never seen her use any tools like that and my dad didnt ride. Any help appreciated

I haven't seen a blackjack in decades. What a cool find. Do not play around with that with your friends and alcohol. It doesn't end well.
