Non-Tradeable Melees

A lot of people have made many threads about certain items that are non-tradeable melees. I don't understand why they are non-tradeable melees. My acc has a lot of non tradeable items and it's quite annoying to see them on my inventory other than trying to trade them away. Eleven Sword is one example , it is from 2013 from the quest that made you free 100+ elves from the ice that held them. This sword is really cool and has many perks that a lot of people want. People make offers on it but I say it's non-tradeable. Making me kinda annoyed because I could've gotten some $$$ items with it.

Things like frying pan, cotton bud, rainbow mallet, blood axe, and other melees should be a part of tables

Woah I forgot about this thread
