Beyond phones and tech is the physical world of appliances, toys, clothing, shoes and others. While quality has certainly gone down in almost all categories, they remain largely repairable. Most things still use screws and not glue. Old appliances are much better made than new ones. Most plans are on the internet. I once opened up a brand new but non-functional electric lawn mower, made in China, only to find that the core magnet had cracked in half at the factory, so they simply glued it back together and shipped it out.
Clothing continues to be old school, made as it was decades ago, and still repairable. Repair is the standard route of finding the last open seam as your entry point into the garment. Parts and supplies continue to be readily available. You can use fancy machines if you wish, but not always necessary. I am very thankful that, with the exception of shoes, no one has caught onto using glue. Shoe quality has markedly decreased with the move to China. Heels are now honeycomb and hollow. When they wear through there is nothing backing them up, the heel fails but is integrated into the shoe, so you need to buy a new pair of shoes. Maybe shoes are the smartphones of the clothing industry? An old school shoe would have a solid heel that you could repair and reinforce.
Repairability in the physical world is still viable, though product quality has markedly decreased. You buy cheaply and get cheap.
