You work in an office. Nothing you own needs to be tactical.

The tactical aisle sells you a story. It's on the end cap by the checkout lane, in the black-and-tan photos online, and in the desk drawer of the guy two cubicles down. The pitch never changes: something might happen, and you'd be ready. Something might. Odds are it's a dead phone battery and a parking garage gate that won't lift. Preparedness is a good instinct, and it's worth buying. Costume isn't.

The tactical pen

What it promises: A glass-breaker tip, a self-defense tool, and a pen all in one.

Why skip it: It's a pen first, and the makers want you to think it's a weapon second. Many take a specialty refill, so check before you buy. A pen you'd hesitate to lend a coworker isn't doing its main job. And a stressful moment is a bad time to find out you've never practiced with it.

Do this instead: Carry a plain pen you'd let anybody borrow. If you want a way out of a car in an emergency, put a dedicated window breaker and seatbelt cutter in the console. The truck kit piece covers what else belongs there.

When it's worth it: If you like the heft, and it takes a standard refill, buy it as a nice pen. Don't buy it as armor.

The MOLLE backpack

What it promises: Rugged, modular, ready for a mission.

Why skip it: Your mission is a laptop, a charger and a lunch. The webbing loops hold nothing, the fabric is heavy before you pack it, and the whole thing looks like you're deploying from the break room. Nothing in your cubicle requires a MOLLE panel.

Do this instead: Buy a plain bag with a zipper you trust. The zipper matters more than the fabric, and it's the part that quits first.

When it's worth it: If your weekends are range days or a hunting camp, and you'll really clip pouches onto it, the attachment points earn their keep. Buy that one for the weekend and leave it out of the elevator.

The two-thousand-lumen flashlight

What it promises: Blinding output, a strobe mode, and a body that looks like it was machined for a special-forces team.

Why skip it: The big number is a maximum, and the maker's own spec sheet will tell you how long the light holds it. Often that's not long. The strobe does nothing in a stairwell. And a light that's heavy and bulky ends up in a drawer, which makes it a very expensive paperweight. The lumens number is the least useful one on the box. Look at runtime at the setting you'll really use instead.

Do this instead: Get a small light you'll actually carry every day. Check the runtime at medium output and whether it takes a battery you can buy at any store.

When it's worth it: A bright, full-size light by the bed is a smart part of a home-protection plan. It just belongs on the nightstand, not in your pocket.

The mission-ready watch

What it promises: Compass, altimeter, barometer, and a case that looks like it survived a war.

Why skip it: You're checking the time in a meeting. Read what the maker publishes about battery or charging before you assume it's low-maintenance, because many of the feature-heavy models need regular attention. Features you never use are just a worse screen to read.

Do this instead: Buy a plain, well-built watch and keep it a long time. We wrote up the watch you'll still be wearing in twenty years.

When it's worth it: If you hike, fly, or run trails and will use the navigation features, a purpose-built sport watch is the right tool. Be honest about whether that's you or the man you picture in the ad.

The combat folder

What it promises: An aggressive blade, serrations, a tanto point, and a name with "tactical" or "combat" in it.

Why skip it: It's a box opener and an apple slicer, and it looks like you came to settle something. It also can raise eyebrows at an office with a weapons policy. Check your employer's rules and your state and local law on blade length and carry before you pocket anything. If you're unsure, ask an attorney or check your state's official site.

Do this instead: A modest, sharp folding knife with a plain blade shape. The pocket knife you'll carry for ten years is the model to follow. Keep it sharp and clean.

When it's worth it: If your Saturdays are on a farm or a job site, a harder-use knife pays for itself. Buy for the work, not the look.

The tactical belt

What it promises: A rigid rigger-style belt with a heavy buckle that looks ready for anything.

Why skip it: If you don't carry a firearm, you're paying for stiffness you don't need, with a buckle that sets off the airport scanner and looks wrong with a suit.

Do this instead: A good leather belt that fits your trousers and lasts. Dress well, and the belt disappears.

When it's worth it: If you lawfully carry, the belt is the one place to spend. A cheap belt sags under the weight, and a sagging holster is a safety problem and an uncomfortable one. Carrying is a right and a responsibility, so get a purpose-built gun belt from a maker that specializes in them, pair it with a quality holster, and get real training. Check your state's law and your employer's policy first.

The pocket-dump kit

What it promises: Twenty-two items, always on you, ready for anything.

Why skip it: It's heavy, it pulls your pants down, it ruins the lines of a good pair of slacks, and nobody ever needs item seventeen. Carrying more doesn't make you more prepared. It makes you tired.

Do this instead: Five things. Wallet, phone, keys, a small light, and a knife if your workplace allows one. Put a charging cable and a spare pair of socks in the desk drawer.

When it's worth it: A bigger kit is smart, but it lives in the truck, where weight doesn't cost you anything. If you want something that lasts for decades rather than a trend, buy-it-for-life should mean repairable, not expensive.

How to say no at the counter

Salesmen at a gear counter are good at the "but what if" pitch. You don't need a speech.

• "Just the one, thanks. I'll come back if I outgrow it."
• "I'll start with the plain version."
• "What's the return policy if I never use the extra features?"

The best-prepared man in the building is the one with a charged phone, a full tank, and a plan. None of that comes with a patch.
