So I just checked the TSA website and none of it makes much sense. An avalanche shovel with a sharp/serrated edge is out but with a smooth edge would be up to the individual screener as its not strictly prohibited but could be construed as a bludgeoning weapon though one would argue avy shovels do not have enough heft to bludgeon anything bigger than an insect.
Amazing that it's even listed. I found the web page

This will be entertaining reading
Edit: Ooo. No cast iron skillets!
Crampons! Yes with a 'but not advisable'
Thank god, yes to duct tape. Would come in handy if a crack develops in the fuselage
"Emergency Position-Indicating Radiobeacons (EPIRB)"; "check with airline". Is that our beacons? It sounds like our beacons.
Film. What's that?
Hand grenades. So handy for checking avy conditions. Can't even check the in
Harry Potter wand: Yes. Yes? And, I can't bring on my collapsible ski poles? Have they seen what a Harry Potter wand can do?
Ice Axes: No. And sheathed in check in bag, to protect inspectors. I've had my stuff rummaged through and in a mess. Why should I want to protect them?
Light saber: Yes. TSA says the technology doesn't exist for real ones. Oh, ok..., I've been checking in, but yeah, ok...
Live Fish: Yes. But, no mention of dead fish.
Shoe/Snow Spikes: No. Yet crampons are a possibility?? Huh?
Skates, including ice skates: Yes. Guess they haven't tuned skates or skis to know
Ski poles: No. At least I can bring on my Harry Potter wand
Snowboards: Yes. Ok, I see that. How does one submit a request for consideration, the ban on snowboarders?
Snow shoes: Yes. Interesting. Mine are spiked.
Thermometer: Yes. I was beginning to wonder.
Toys (Adult): Yes. In have lots of toys when I travel to ski. I mean, it's ask all toys. That's very unhelpful.
Trophy, Yes. How about 57 trophies? Trophies that include reindeers (live), crystal, like Mikaela's?
Waffle Iron, yes. But, I can't bring my backcountry cast iron skillet?
Walking sticks, No. Damn, they've thought of everything.
@headybrew, I've give though the entire just and no where is the any mention of avy shovels. What gives? Oh well, doesn't matter. I've got my Harry Potter wand
Ski talk - at the highest level
