I need some advice. I’m looking at vintage Barlows and pocket knives in general, primarily of the single-bladed jack knife variety (THIS IS NOT A WTB THREAD). Can anyone give me some information on what brands to look for? There seems to be countless old brands but I have very little clue as to which brands represent high quality and which are just kind of meh. I get that it will be a different metric than today’s since the bygone eras tended to probably not obsess over every small detail like we do. However, there has to be some sort of brand hierarchy, right? Any help is appreciated. Thanks everyone.
