Two heirloom categories
Hand tools publish the best warranties of anything on this site. Watches publish some of the worst - and are the only things here that are genuinely designed to be rebuilt forever.

Watches and hand tools sit together because they are judged the same way: not on how long they survive untouched, but on whether there is a documented path to keep them working. They arrive at opposite answers.
Nowhere else does a buyer get terms this good. Knipex publishes a Lifetime Limited Warranty. Klein warrants tools made for commercial or industrial use for the normal life of the product. Channellock's Built Strong Limited Lifetime Warranty is admirably specific about its limit: it covers defects in materials and workmanship, not the natural wear that comes from hard work - possibly the most honest sentence in any warranty we read for this site. Wera publishes a lifetime warranty against breakage from defects, with bits and L-keys excluded as consumables. Craftsman's full lifetime warranty on hand tools survived the brand's change of ownership, and claims are still made by walking into the shop.
TEKTON goes furthest and it is worth naming: no time limits, no receipts, shipping paid by TEKTON, and claims filed before 2pm Eastern on a weekday ship a replacement the same day. The tools are good. The process is exceptional, and process is most of what a warranty actually is.
Estwing deserves credit for the opposite reason. It states plainly that its warranty is not a lifetime warranty: it warrants against failure in normal use and not against misuse, abuse or wearing out. A one-piece forged hammer does not need a lifetime warranty - it has no handle joint to fail - and the company declines to pretend otherwise.
A knife wears out by being sharpened, which is a strange thing to warrant, and the brands handle it differently. Benchmade's LifeSharp program re-sharpens, cleans, oils, inspects and adjusts a knife free for the life of the knife - you pay shipping one way. Spyderco warrants against defects for the life of the product and explicitly excludes improper sharpening. Buck's Forever Warranty covers defects for the life of the knife and, unusually, the company will repair misuse damage for a reasonable fee rather than simply refusing you. Opinel publishes a lifetime warranty on a seventeen-dollar knife.
Mechanical watches are the most genuinely rebuildable objects on this site - a movement can be stripped, cleaned, re-lubricated and re-assembled indefinitely, which is why 1960s watches run today. The warranties are short. Seiko raised its worldwide warranty to three years in October 2024, which is now the best in this group. Hamilton publishes twenty-four months. Tissot publishes two years, three on COSC-certified models. Orient publishes one year on standard models.
The real durability question for a watch is not the warranty at all - it is whether a service is economically rational. A full service costs more than a Seiko 5, which means those watches are run until they stop and then replaced, whatever their theoretical rebuildability. Above roughly $400 the arithmetic flips and servicing becomes the obvious choice. That threshold, not the spec sheet, is what separates a watch you will own for life from a watch you will own for a decade.
The honest exception is the G-Shock. It is not rebuildable in any romantic sense - the module is replaced, not repaired - but straps, bezels and batteries are cheap and user-replaceable, which is why thirty-year-old DW5600s are still in daily use. Cheap, replaceable parts beat expensive, serviceable ones more often than enthusiasts like to admit.
Maglite warrants its lights for the life of the original owner and sells o-rings, lenses, switches and lamp modules as spares - genuinely rebuildable. Streamlight publishes a limited lifetime warranty with a sensible two-year carve-out for electronics and rechargeable cells. Fenix uses a removable 21700 cell, so the one part that truly wears out can be replaced forever. Olight publishes a lifetime warranty including the built-in battery - but that battery is not user-replaceable, which is the trade. Pick the architecture that matches how long you intend to own it.
How we judge this category. Every pick here is scored on the same three things: what the published warranty actually covers, whether the product can be repaired and by whom, and what it is made of. We own none of these products and run no test lab. The full method is here.
