A metal spoon feels colder than a wooden one at the same temperature because metal carries heat away faster.

The longer version

A metal spoon conducts heat readily because its electrons and lattice carry energy outward quickly. Wood is riddled with tiny pockets of trapped air, and air is a poor conductor, so warmth leaves the surface slowly. Both objects sit at room temperature and hold the same amount of heat per unit mass.

What the hand detects is not temperature but the rate at which heat is drawn away. Faster removal cools the skin more, and the nerves report a colder surface. This is why polished stone, water and metal all feel cool, while cloth and foam feel warm by comparison.
