Don't worry, @Avirup. You're not the first and you won't be the last. I know people who have been CUT UP by the props. @CarolineTyler's advice isn't just a good idea. It's a biblical level Commandment if we want to avoid trips to the Emergency Room.
I hope your thumb heals rapidly. Thank you for making this post, as a reminder to us all to take the darn prop off!
