I wanted to see the reasons given for walking with a rod tip forward. So I searched for sources on the web that say to walk with the rod tip forward and could not find any. I then searched Google for “breaking fly rods” and found three more sources that say that carrying the rod tip forward is is a good way to break rods.

“Tip 15: When carrying a fly rod, hold it “backwards”: i.e., with the butt end in your hand and the tip facing the opposite direction of travel.”

"3. Poke the rod tip in the ground while walking. The setting can be anywhere: a river bank, a beach or a flat. You can be alone, with a friend or accompanied by a guide. Whether you are observing the water in search for fish, daydreaming or chatting away with your companion, it doesn’t matter.
Point is, you are not paying attention and unnoticed, the rod tip goes slowly down and suddenly bores itself into the ground. If the walking pace is high, the sanction comes immediately: snap! If you walk slowly or your buddy stops you in time, you can get away with a warning.
How should you carry a rod ? Hold it horizontal but backwards."

"7. Carry your rod through the bushes, tip first. Pointing your rod backwards when you?re bushwhacking is really boring ? the strong part of your rod hangs up first, and you?ve got plenty of time to maneuver before the fragile tip section comes bouncing through.
If you point your rod straight in front of you though, you?re forming a giant, weak spring, and the exploding tip of your rod will do a great job letting you know that it just got hung up on a tree branch."
