I think BRK's knives are more handmade than not, but it's kind of like leather to me. Bonded leather is still technically leather, but it's obviously inferior to full-grain.
Fully handmade to me would be made from bar stock and block cuts of handle material with the fasteners made from round stock metal or composites.
Grades of handmade would range from using purchased fasteners on the most minor end (mostly handmade) to using blanks with the primary bevel and mostly-formed handle scales on the extreme end (barely handmade at all).
Fully factory made would be everything but final sharpening done on machines.
Hand-assembled would be final sharpening and assembly and fitting of factory-made parts.
There are, of course, good knives made on both ends of those spectrums as well as everything in between. Having some level of factory machine manufacturing involved doesn't miraculously make a knife worse, just less handmade.
That's a separate issue that's not really relevant, because whether it's hand made or not has nothing to do with whether the hands that put the steel in the waterjet cutter... or the saw... or the forge... put the correct steel in. You could waterjet, hand-cut, or hand-forge the wrong steel, the method you use to cut the blade blanks is not relevant to that. Stock steel bars have to be marked for a reason, so people don't do that. That's an inventory and process management issue at Bark River not relevant to whether or not their knives are handmade.
