Shades of meaning
Fernald has no entry of its own for utensil; he lists it under tool.
Where he writes about it:
A utensil is that which may be used for some special purpose; the word is especially applied to articles used for domestic or agricultural purposes; as, kitchen utensils; farming utensils. — from tool
Implement is for the most part and utensil is altogether restricted to the literal sense; instrument, machine, and tool have figurative use, instrument being used largely in a good, tool always in a bad sense; machine inclines to the unfavorable sense, as implying that human agents are made mechanically subservient to some controlling will; as, an instrument of Providence; the tool of a tyrant; a political machine. — from tool
