Just try to take it from my son, he got his Totin' Chip for his knife and his Firem'n Chit for carrying fire-starting tools (matches or flint/steel). He's not giving up either of them.
Also, they're still able to earn the Rifle Shooting, Shotgun Shooting, and Archery merit badges. They won't be going away in our troop any time soon.
Fires will probably be a thing of the past too. GoreBull Warming and all.
