Taylor Brands would be Tata... an overseas, very low-cost company that's bought up lots of formerly respected makers.
Gerber would be Rover-- used to be respected, used to build some really great products, on a long downhill slide but still sell a ton.
Opinel is Vespa-- quirky, good value, way more common in Europe than in the US but owners swear by them.
Leatherman is International Harvester-- sure, they make an occasional car or small SUV, but that's not their primary product line.
