Solution

The wooden handle would have been warmer than the metal blade because metal is a good conductor of heat. So, in cold night, metal blade would transfer its heat to cold environment. But wood, being a bad conductor of heat, would not transfer its heat to cold surrounding and would remain warmer than the metal blade.
