Flying w/ Ice gear

I will be flying to Calgary to do some outdoor winter activities. Does anyone know if I have to check a bag for crampons??? My assumption is yes, but I am not sure. 

Definitely check anything sharp and pointy

Check it!

Crampons                         Carry On Bags: Yes (Special Instructions)Checked Bags: YesCrampons are generally permitted in carry-on bags. However, TSA officers have the discretion to prohibit an item if they feel it may pose a security threat.

if i have TSA precheck, can i just wear my crampons and carry my tools over my shoulder?
