The clipper
Wide blade, guards from an eighth of an inch upward, built to move fast across a scalp. It is the tool for head hair and for nothing else in particular. Hair clippers here start at the Philips HC7650 at $90 and run to a professional Panasonic at $200.
The beard trimmer
Narrower blade, a range that starts below one millimeter, and steps fine enough to hold a stubble at an exact length. The specification that matters is the step size between one and three millimeters — under an eighth of an inch, the band a designer stubble lives in, and the thing most listings never quantify. See beard trimmers, and how to hold a stubble for the counts.
The shaver
No guard at all: a foil or a set of rotary heads cutting at skin level. It does not trim and it is not meant to. Rotary suits a neck that grows in several directions; foil suits a face shaved daily. Both families carry a scheduled part, which is the running cost worth checking first — the heads on this site are $25 to $34.
The body groomer
Rounded teeth and a guarded head, for skin that is not flat. This is the one substitution people try and regret, because the blade — not the comb — is what differs. The Braun BG3530 at $57 is the plainest example on the body groomers shelf: two comb lengths, no foil head, and it does not pretend to shave.
Where one tool covers two jobs
An all-in-one kit covers beard, body and often head hair from one motor, and all four here publish a price — $59 to $165. A OneBlade-type tool trims with a comb and shaves without one.
Both are genuine answers if the ranges suit you. The check is the same in each case: where does the range begin. A kit that starts at 3 mm (0.12 in) cannot hold a stubble, whatever else is in the box.

What people ask about this
Can a beard trimmer cut head hair?
Badly, and slowly. The blade is narrower and the guards are shaped for a face. It works in an emergency; it is not the tool. For a full head you want a [hair clipper](/hair-clippers/), whose blade is two or three times the width.
Can I use a clipper on my body?
A [body groomer](/body-groomers/) has rounded teeth and a guarded head because it is designed for skin that is not flat. A clipper does not, and fitting a different comb does not change the blade.
Is one tool ever enough?
For one job, yes. For two jobs, an [all-in-one kit](/multigroomers/) shares a motor across heads, and the Philips [OneBlade](/reviews/philips-qp2824/) at $95 trims with a comb and shaves without one. Neither replaces a proper clipper on a full head — check where each range begins and ends before deciding it covers you.
