For certain things, yeah I think so. Good knives, cast iron cookware. Fountain pens yes, as long as spare parts are available. Meze headphones are designed to be completely user serviceable, but that will entirely depend on if they continue to make spare parts.
I would say a majority of modern electronics and appliances are all designed for obsolescence. Born to die. Surprisingly, I have bought things off AliExpress that are more serviceable than most mainstream electronics! Linux-based gaming handhelds that are assembled with screws, no clips or glue. With replaceable components. Headphone amps with socketed op-amps so you can replace or change them at your will.
The real BIFL these days is definitely priced at luxury levels. Speed Queen washers and dryers. Sub-Zero refrigerators. Tudor watches.
With how electronic everything is these days, if you want to BIFL, you better get good at diagnosing and repairing tiny surface mount PCB components. That’s where I’m at now, with a lot of my game consoles. I can toss an SSD in my PS2 and play some San Andreas. No discs, no laser issues! But that PS2 still has 24 year old capacitors, and they’re probably going to die at some point.
I have no idea regarding locally sourced textile goods, sorry. Hammer Made has great men’s shirts, but I don’t know anything beyond that.
Yes, I did. I bowled a lot when I was younger, I was even on the varsity bowling team at my high school. That was the last time I regularly bowled. Now it’s like, once or twice a year.
