I bought a #4 Faithful a few years ago then didn’t get chance to use it for a year or two as I moved house and workshop. When I came to use it I discovered it was needing a lot of fettling, luckily I’d just read Schwartz’s book on hand planes https://amzn.to/3SSj8k4 so I spent a day flattening everything that needed it (which was everything), and quite some time sharpening. When it was all done I managed some very fine passes on some knotty oak which I was rather chuffed with. The next day on my second pass the blade dug in quite badly so after some swearing I had a look at the plane and discovered the frog had loosened itself so I set it again and tightened it down. Turned out whatever I did the screws holding the frog down would work themselves out causing the blade to dig in.
I replaced it for a Clifton #4 and while it too needed fettling it wasn’t to the same degree as the Faithful and it hasn’t stopped cutting since.
