[Nuanced]

Summary: 
Enchanting a Boulder material weapon (Dagger, Shuriken) with a Feather has failed to halve the weight.

      Details: 

• My weapons are the Venomous and Knock Down variants of Shuriken.
  
• Boulder material is very heavy, so naturally I've enchanted them with the Feather enchantment to alleviate this.
  
• I did the enchants myself. I am a level 1 Enchanter +1 from LE.
  
• My weapons still weigh a ton with no noticeable changes in combat.

So, if my numbers are right- Depending on if Talent and Thinning weight are taken before or after the weight halving-

The top one should weigh 10.25 at most, 5.5 at least.
The bottom one 13.75 at most, 9 at least.

With my other equipment weighing 0, this should make me at heaviest 24 weight.
Even if the calculations are played out differently, the numbers aren't adding up to any difference granted by the enchant.

I have no idea if this is intentional or not, but I found it worth bringing up since I've a feeling this should work proper.
