Freezer keeps -18C, but it's a big difference between touching ice and touching metal.

Once in St.Petersburg I went from an apartment at the sixth floor, down to the car, picked up some skates at -20C, and carried them up to the sixth floor holding the skates by the metal. Not smart at all! I had marks after the iron on my hands for several days after.

Oh it's hard and not smart as you said 😲
