BOYKINLP, it is nice to talk with a fellow antique knife guy. Early Case, xx and earlier, was my main focus for decades. Old Remington's were hard to find in my area. In my early collecting days, I believed W.R. Case and sons and Case Tested's were the elite "Snap-On" of the knife world, I have come to the conclusion there are some other outstanding brands. And ordinary brands that did outstanding work. Case could not hold a candle compared to early Remington bone stag. Those early Remington's with their dark brown bone stag has me weak in the knees. One thing I always looked for as a way to determine quality and care and pride of manufacture was the blade design itself. And in many cases, Case fell short by simply stamping out a flat blade with small nail nick and lack luster shape. Remington stood head and shoulders above most all others of their day. Their early long spear blades with cut swedges, and often not only on the main blade but even the smaller blades, and long pull was sexier than any girl in high school. When a manufacturer goes the extra mile to sculpt blades is my mark of excellence. Weird side note, that extremely rare stag handled baby bullet muskrat doesn't have sculped blades just flat stamped. As for the "6", this refers to 6 Remington's that are ultra-rare and very valuable. Without my books to remind me I can recall a few. One was the afore mentioned baby bullet muskrat #4466. Another was a bullet knife called the H.T.T. for hunter , trapper, trader, then their was a 5 blades sowbelly. Those are the ones that come to mind at present. My early interest was bone scales only. Now I lean towards odd US manufactures and fancy celluloid scales. There are some beauty's out there. I find myself carrying of all things, a very early Imperial, don't judge, serpentine stockman with cut swedge main blade, long pull and with scales I can only describe as linoleum. Green and black and looks just like the flooring in grandma's kitchen from the 1930's. Nickle bolsters and shield, with brass liners. Quality all the way and the steel is superb and easy to keep shaving sharp.
