Knipex Cobra and/or Pliers Wrenches. Unbelievably helpful, and they will actually last forever. The XS variants are popular as a pocket tool.

Mora Companion knife. Srsly, if you need one utility knife in your life, it’s this. Dang cheap, good steel, easy to (re-)sharp, forgives a lot of abuse, and did I mention it’s dang cheap.

Lundhags shell boots (e.g Park, Forest, Vandra). Best bad weather hiking boots. Basically indestructible, easy to maintain and repair. Waterproof, no GTX membrane that pollutes the environment forever but dies after a year or so. But be aware you need to take out the insole to let it dry and wear several socks. They’re waterproof from both sides… If you can live with that they’re excellent value, insanely comfortable, and will probably outlive you.
