Crampons
Crampons are generally allowed in carry-on, but officer discretion and their sharp spikes make checked baggage the more reliable option.

Carry-on details
Generally allowed, but pack them in checked baggage if you can. TSA permits crampons in carry-on, but their multiple sharp metal spikes mean checkpoint officers have unusually wide discretion here — a call can go either way depending on the officer and checkpoint.
Checked-bag details
Allowed. Crampons are reliably accepted in checked baggage. If you're also traveling with an ice axe (which is checked-only regardless), packing crampons alongside it in the same bag is the simplest approach.
Special instructions
Wrap or sheathe the spikes to protect baggage handlers and your other gear, and pack them in checked baggage if you want to avoid any chance of a checkpoint judgment call.
