... I don't know what any of the words you said mean ...
I can't guess what words might baffle, other than blue; and that's easily explained.
We used to ride the big beemer to a B&B in Tidioute PA every Fourth of July to attend the Battle on Bull Mountain at Hickory Creek Ranch. The little town holds a 4th of July parade literally a block and a half long (unless the fire truck gets called away, as happened one year right before the parade, in which case a block will do). A gal on a horse holding a flag, a Model T, the PBR rodeo clown in his go-kart, about a dozen fellers in Civil War garb calling themselves Buffalo Soldiers (I dunno why, cause they're all white), and the fire truck long's someone didn't light up his trailer in the woods playing with fireworks. So. One year workers from the Queen Knife factory in Titusville (birthplace of the oil well) set up a card table in front of the Ace Hardware & sold me one of these:
Of course, when it was brand new, this high carbon steel knife was shiny. Naked high carbon steel rusts quickly. So what I did, I walked into the grocery next door and bought a lemon. Stuck the knife in my lemon, under the approving nods of the factory guys, for as long as it took for the parade to pass, then folded it up & let the lemon juice do its work. Not a chemist; don't even play one on TV; just know lemon colors your steel a midnight blue that prevents rust. It's called blueing your steel. I took a high carbon kitchen knife like this Old Hickory to sea:
Blued it before I used it. Took and Old Timer pocket knife like this one, back in the days before they made them stainless:
Used it up until there was only a sliver left. Always at my waist in a leather holster on a fathom of line. Dove with it, rigged with it, never rusted. The advantage of high carbon is you can get a super sharp edge. Disadvantage is rust. Easily cured by blueing.
Ever get yourself a new rifle? Well, they ordinarily blue the livin hell outta those barrels so's they're jet black. Done right, you can get an irridescent effect. Stop at any sporting goods store, they'll sell you a bottle of chemicals to do this. Turns out they also sell you a bottle of blue remover, in case you want to renew your blue. Happened to have one such.
That explain your puzzle?
