"Our Blades Are Sharp" - Why those exact words?

[Schwarze Sonne]

"Our Blades are Sharp" is a motto meant as reassurance to their victims that at least the flaying knives would be sharp thus reduced the pain they would have suffered during the flaying process.

The Boltons are unexpectedly kind and considerate.

 

It's a blatant lie of course. If the Boltons are truly thinking about their victims, they should at least use obsidian blades. Those are the sharpest blades in the world. Instead they probably used copper blades, then steel blades, without sharpening.

Also, I believe the Bolton sigil and Roose Bolton's bloodletting practices are associated with rubies.

Very interesting post overall, but If I recall correctly the Boltons wear garnets. Both gems are blood colored, but Tywin thinks that garnets lack the fire of rubies. Which would seem to make rubies a good symbol for Fire and Blood.

Ramsay was clad in black and pink—black boots, black belt and scabbard, black leather jerkin over a pink velvet doublet slashed with dark red satin. In his right ear gleamed a garnet cut in the shape of a drop of blood. - ADwD, Reek

Ramsay Bolton stood beneath them, clad in high boots of soft grey leather and a black velvet doublet slashed with pink silk and glittering with garnet teardrops.

After a moment of silent prayer, the man and woman rose again. Ramsay undid the cloak that Theon had slipped about his bride’s shoulders moments before, the heavy white wool cloak bordered in grey fur, emblazoned with the direwolf of House Stark. In its place he fastened a pink cloak, spattered with red garnets like those upon his doublet. On its back was the flayed man of the Dreadfort done in stiff red leather, grim and grisly. - ADwD, Reek
