Correct me if I'm wrong but weren't the earlier knives, (by that I mean 20s-50s) mostly dropped forged, where as beginning after the 50s more steel mills were sellin' rolled steel where the manufacturers only had to have them die cut and finished on a belt grinder for the bevels.
The physics of drop forgin' would allow for more compacted thinner edges where rolled steel ground to shape, (bevels) would depend more on a proper heat treat in regards to edge holdin' ability.
I have quite a few older knives that were made in Germany, or early Western Euorpean manufactured knives that have forged blades, even my Case small Coke Bottle Damascus takes an easy edge to razor sharp and holds it three to five times longer.
I find myself gettin' ready to touch up the edge on an older forged blade and it seems to never need it, compared to some of my more current "Super Steel" knives.
I can't say when the steels changed 60's with more modern steel makin' methods or the 80s when greed was the thing runnin' most corporations and if ya wanted to compete ya had to make concessions somewhere.
There now that I've used up my quota of intelligent comments I'll go back to my normal hick self and remind ya'll one more time to get in on any of the giveaways on the traditional forums one of them ends in about 30 minutes still plenty of time to get in on a free Boker Canoe Model 200, (selfless plug for contest)
Very good question, sir! And it brings up the old forging vs stock removal arguement.
Buck knives used to drop forge thier knives back in Hoyt Bucks day. With the mechanization that transformed this country just after WW2, there were breakthoughs in the way metal products were produced. The rolling of steel became more popular, and the Buck family investigated this method. From what I remember reading back in the 1960's and early 70's, Buck was buying thier steel from the Universal Cyclops Mill in Cleveland Ohio, and Universal was rolling the steel. Acording to the factory litature of that time, Buck stated that the rolling prosess alligned and compacted the mollocules in a very similar way to the drop forging. Wenger of Switzerland also used a rolling method of treating thier steel for the sak's they made. Both companies were known for good knives.
Drop forged or rolled, that is the question. Is it nobler to suffer the sparks and flying cinders of pounding away on a hot piece of steel, or have it delivered rolled and ready to grind? Does it make a difference?
Now having used up MY quota of semi-intellegent comments, I'm going to retire to a nice toddy and my favorite chair by the fire.
