I went to NAPA for Oil and Found my New Favorite Everyday Carry Knife – The TRUE Berm Keychain Knife

It was a classic Midwest Tuesday, gray skies threatening rain, and, as if on cue, my oil life had dropped below 10%. Synthetic oil isn’t cheap, but neither is a blown engine. So I grabbed my keys, smiling at the familiar inevitability: time for a NAPA run. Then I pointed the car toward the one place that always feels like a treasure hunt, the local NAPA Auto Parts store.

TRUE BERM Keychain Knife

What I expected was a quick in-and-out for two quarts of 5W-30 full synthetic, a fresh filter, and maybe a drain plug gasket. What I got was an unexpected upgrade to my everyday carry setup that has since become one of my favorite possessions. Tucked among the impulse buys near the register sat the TRUE BERM Keychain Knife – a thumb-sized flipper that’s equal parts clever engineering and pure utility. I bought it on the spot, clipped it to my keys, and haven’t looked back. This isn’t just a product review; it’s the story of how a greasy errand turned into a lesson in preparedness, self-reliance, and why the best tools are the ones you never notice until you desperately need them.

Quick Life Tip

Let’s back up. Why bother with a DIY oil change at all? Modern cars are marvels, but they’re also high-maintenance divas. Motor oil does triple duty: it lubricates moving parts to cut friction, carries away heat so your pistons don’t weld themselves together, and suspends contaminants so they don’t grind your bearings into dust. Over time, roughly every 5,000 to 7,500 miles for most synthetics, the oil breaks down, picks up metal shavings, and turns into a thick, acidic sludge. Skip it and you’re looking at reduced fuel economy (up to 2-3% loss), sluggish acceleration, and eventually costly repairs. According to general automotive wisdom (and my own wallet’s painful lessons), proper oil changes can add tens of thousands of miles to an engine’s life and save you hundreds in shop fees. One change runs $30-40 in parts versus $80-120 at a quick-lube. Do it four times a year and you’re banking real money while actually understanding what’s under the hood.

Back to the True Berm Knife

Walking into NAPA is always a sensory overload in the best way. The fluorescent lights buzz overhead, the air smells like rubber hoses and fresh grease, and every aisle whispers “project time.” Customers in Carhartt jackets chat about torque specs while kids stare wide-eyed at the wall of spark plugs. I headed straight for the lubricant aisle, scanning the color-coded bottles until I found my match: full synthetic 5W-30 that flows like silk in Indiana winters yet holds viscosity when the highway gets hot. Grabbed the filter, a funnel, and some new Mechanix gloves because nobody wants oil under their fingernails for a week. Tip: Get Black it hides oil much better…..

As I waited in line, my eyes wandered to the end-cap display of tools and gadgets. That’s when I spotted it: the BERM Keychain Knife, hanging innocently among multi-tools and flashlights. At first glance it looked almost too small to be serious, closed, it’s barely longer than a standard key fob. But I picked it up anyway, and the moment I felt the weight (a featherlight 0.17 pounds) and the textured G10 handle, I was intrigued.

Flipped it open with the thumb stud, smooth as butter thanks to the ball-bearing pivot, and there was this perfect 1.5-inch modified clip-point blade in 7Cr17MoV stainless steel with a Titanium Nitride coating that gives it a sleek, dark finish. The liner lock clicked into place with authority. Integrated carabiner on the back let it clip straight onto a keyring; the deep-carry pocket clip was reversible and removable. For under thirty bucks, how could I say no?

I tested the edge on a scrap of cardboard from the counter. It sliced like it was born for the job. The sales associate noticed my grin and nodded: “People sleep on those little flippers until they need to open a package one-handed in the parking lot.” Sold. I added it to my haul, paid, and drove home feeling like I’d just upgraded my entire keychain game.

Another life tip

Back in the driveway, it was go time. Here’s the step-by-step for anyone who wants to try their first oil change (and why the BERM made it easier). Safety first: park on level ground, chock the wheels, let the engine cool 10-15 minutes so you don’t get a face full of 200-degree oil. Jack the front end, set it on jack stands, never trust the jack alone. Slide under with your catch pan, locate the drain plug (hex or square drive), loosen it with a wrench, and back it out the last few turns by hand. Hot oil pours out fast; let it drain fully while you tackle the filter. Spin off the old one (counterclockwise), wipe the mounting surface clean, dab fresh oil on the new filter’s gasket, and hand-tighten until snug plus a quarter turn. Reinstall the drain plug with the new washer, torque to spec (usually 18-22 ft-lbs – check your manual). Lower the car, pop the hood, remove the fill cap, and pour in your quarts slowly. Start the engine for 30 seconds, shut off, check the dipstick, and top off. Recycle the old oil at any auto parts store, they take it free.

Total time: 45 minutes. Mess factor: minimal with the right gloves (Mechanix Gloves Recomended). Satisfaction level: through the roof. And right there in the middle of it all, the BERM proved its worth. The oil filter packaging was that infuriating clamshell plastic. One flip, one clean slice, and it was open. No more hunting for scissors or tearing it with my teeth like a caveman. Later that same afternoon I used it to open amazon boxes as well as open a few letters in the mail. The blade stayed razor sharp, the flipper action never failed even with slightly greasy fingers, and the carabiner kept it exactly where I needed it, on my keys.

Over the weeks since, the BERM has become quite useful in ways I did not anticipate. The Titanium Nitride coating shrugs off moisture and fingerprints; the G10 scales give confident grip even when wet. At 4.1 inches open and a sub-2-inch blade, it’s legal pretty much everywhere and disappears in the pocket or on the keys without printing or weighing you down. Compared to bulkier folders I’ve carried, this one is pure minimalism done right.

Here’s the Insightful Part

The reason this little knife earned a full article on PoszPerspectives. In a world obsessed with apps, subscriptions, and “smart” everything, there’s something profoundly grounding about a tool that requires zero batteries, zero updates, and zero subscriptions. The BERM embodies a quiet philosophy of readiness: you don’t need to be a survivalist to appreciate having the right edge when life hands you cardboard, rope, or a loose thread. It’s a reminder that self-reliance isn’t dramatic; it’s the accumulation of tiny, competent moments. NAPA itself feels like a temple to that idea, a physical space where people still solve problems with wrenches and know-how instead of just clicking “buy now.” Wandering those aisles isn’t shopping; it’s connecting with the mechanical world that keeps us moving.

I’ve since looked up the BERM family – TRUE makes a cleaver and tanto version too – but the keychain model is the perfect gateway drug for anyone dipping their toes into EDC. It’s not pretending to be a tactical tanto or a kitchen chef’s knife. It’s honest: a compact, reliable cutter that lives on your keys and stays out of the way until the moment it saves you frustration. Maintenance is laughably simple, wipe the blade, drop a tiny bit of oil on the pivot every few months, and it’s good for years.

No Caption

Life’s best upgrades often hide in plain sight – on the end cap at your local auto parts store, right next to the motor oil. Next time the dashboard light comes on, don’t just fix the car. Upgrade the way you move through the world. You’ll thank yourself the next time you need to open a package one-handed while juggling groceries, keys, and a phone call. The BERM didn’t just slice plastic that day; it sliced through my old habit of being unprepared for the little things. And that, more than anything, is why I’m still smiling every time I flip it open.
