The hilt not the tang, besides the hilt is wrapped in layers of leather so something a bit more fancy something of a higher stationed officer would use. Silver is great for undead, ghosts and werewolves and they do glow in light unlike the dark ebony. Sure Silver may not be strong as Ebony or Daedric but Silver has alwasy been better than steel and iron in the TES series. The blade of Ebony would be left untouched. Plus have you seen Mehrune's razor in SKyrim? It has this strange ball as part of the decraction connecting the tang to the hilt. perfectly feasable to have a small gem here or there much like the daggers in the pictures.
But again, why would anybody want that on a silver weapon?
Or on an ebony or Daedric weapon? Those weapons are incredibly expensive and difficult to make. You don't create them to just put them away and let them lay around for nothing... At least I'd be seriously upset with a gift like that. Give me something useful.
As for Mehrunes Razor, you don't mess with the artifact of a Daedric prince...
Or at least the return of crossbows, whatever happend to crossbows?
After the events of Morrowind the Nerevarine used a flying spell to go up into the sky, there he used a hot air balloon to stay a drift for a while longer when a gaurd accidently shot a crossbow bolt through the balloon causing the Nerevarine to fall down... Of course the Nerevarine used a slowfall spell but too late and then he landed ontop of a spear... Piercing his body killing him instantly.
From that moment on, Levitation, Slowfall, Spears and crossbows have been made illegal.
