No one asked but here's an unofficial thread of Wirecutter picks that are basically "buy-it-for-life":

The @LandsEnd Waxed Canvas Duffle is the toughest bag we could find that's also consistently available, and its lifetime warranty has you covered, too. https://wrctr.co/3kEUvoZ 

After years of use, the @AllClad Stainless 12" Covered Fry Pan remains our pick for the best skillet.

Though it’s pricey, we’re confident this skillet is a BIFL item that will provide you with years of use (it also comes w/ a limited lifetime warranty) https://www.nytimes.com/wirecutter/reviews/the-best-skillet/#our-pick-all-clad-stainless-12%e2%80%b3-covered-fry-pan

Expect to pay around $40 or more for a Peugeot Pepper Mill, but know that it provides a lifetime’s worth of use.

It's been a favorite since its introduction over a century ago & it’s still the best due to its ease of use, even grind, & classic look. https://www.nytimes.com/wirecutter/reviews/best-pepper-mill/

What experts say about it:

"Still the only pepper mill I use; it's amazing" -Martha Stewart

"The BMW of grinders" -chef Michael Symon

"No mill, in my experience, creates a more consistent grind. They're beautiful, too, like noble wooden chess pieces" -food historian Bee Wilson

Our upgrade pick for carry-on luggage, the @BriggsandRiley Baseline Domestic Carry-On Expandable Spinner, offers superlative build quality, an ingenious compression system, & comes w/ a lifetime repair warranty (even for damage caused by an airline).

In fact, Wirecutter founder Brian Lam has carried a two-wheeled Baseline while traveling 150k+ miles over the years. After considering all the bags in our test, & logging 40k miles w/ a similarly priced bag, he’s convinced the Baseline is the best for anyone always on the move.

An unbeatable classic: The @KitchenAidUSA Artisan Series 5-Quart Tilt-Head Stand Mixer

It tackles nearly any recipe w/ ease & won’t knock around on the counter. It’s sturdy, easy to clean, & a time-tested appliance worth the investment & counter space.

The Le Creuset Signature Enameled Cast-Iron Round French Oven is the best Dutch oven, and it's very expensive at around $360.

But if you get it, the Le Creuset will probably outlive you, and maybe even the kids you pass it down to. https://www.nytimes.com/wirecutter/reviews/best-dutch-oven/#upgrade-pick-le-creuset-signature-enameled-cast-iron-5%c2%bd-quart-round-french-oven

Made from a single piece of steel, the Estwing E3-16C has an indestructible steel design, perfect balance, a great grip, and a stellar reputation: plenty of carpenters agree it’ll last a lifetime.

Observe a new Estwing compared to a well-used Estwing:

The hammer on the right served our writer during a decade of construction & carpentry. The Estwing is so universal on construction sites that he added a blob of weld to the neck to be able to tell his apart from the others

If that still isn't enough, check out the comments on our hammers guide, where you can see people talking about Estwing's being passed down through the ages.

"You won't regret getting the Estwing, and maybe your grandchildren will also be glad you did." http://disq.us/p/1fdocu2 

It's expensive, but the @AllClad Stainless 10-Piece Set is the cookware set you'll likely never have to replace.

Because it’s so durable, All-Clad was the name that came up again and again when we spoke to the pros. https://www.nytimes.com/wirecutter/reviews/best-cookware-set/#upgrade-pick-all-clad-stainless-10-piece-set

If you want a vacuum that can clean the heck out of your home for decades (30 years isn't unheard of), buy a Miele canister vacuum.

Every industry expert we’ve spoken w/ (even one from a competing brand!) has told us that they're simply excellent.

The @Filson name has long been a byword for rugged quality, and the Filson Original Briefcase is part of that legacy.

Its not as dressy, but the Briefcase is basically bombproof & comes w/ a lifetime warranty to boot.

The @Leatherman Skeletool CX is an investment: at around $80, it's not the most expensive multi-tool we looked at, but it's up there

It's backed by a 25 yr warranty, but unless you lose them or are doing something truly stupid, they should last for life https://www.nytimes.com/wirecutter/reviews/best-multitool/

Not everyone needs a backpack so tough that it will survive decades of abuse. But for those who do want—and can afford—such a bag, it can travel with you to the office and to any corner of the globe, for any activity, year after year. Our picks: https://www.nytimes.com/wirecutter/reviews/buy-for-life-backpack/

A previous gym bag pick wasn't strong enough to withstand our long-term testing. Originally, we liked its cost & build, but none of that matters if a bag can't handle wear & tear

So we enlisted squat world record holder Roy Glenn for destructive testing https://wrctr.co/2YJaQyz 

Our current top pick, the King Kong Jnr Kong, is a buy-it-for-life gym bag: it's functional, has a 25 yr warranty, & was the toughest bag we tested.

In our destructive testing, Glenn took one look at this bag, threw up his hands, & said, “No f*cking way.” https://wrctr.co/35gHQ3x 

These buy-it-for-life picks shouldn't wear out except in the toughest of circumstances. Something failing on one of these BIFL products should be a surprise, not an inevitability.

Get these, and you'll likely never have to think about buying it again.
