I can't recall Thanos ever using a melee weapon at all.

depends whether their durability still in effect. Odin as proficient as he is more with melee weapon would fall eventually if Thanos immortality and eternal physiology still in effect. If only offensive powers are disabled in this fight, Thanos. If not, Odin. If they are still allowed to use powers, Odin in a landslide.
Yeah although he was on the defensive against a formidable opponent. some guardian or such. I have to go back and check because I'm not sure if the battle was an abstract one of the mind. All the same, it shows that he has used a weapon, or knows how to use one. He also briefly deflected a blow from Morg with a weapon.
Honestly no lol, I just like Thanos more than I like Odin, and I was answering the question of has Thanos ever used a sword. Thanos could win, but I see him being pushed back, and put on defense. One of Odin's things is weapons. He obviously wins. IMO.
If they were regular swords then durability would be more of a factor, but dude these are Light Sabers, there is no minor cut just severed limbs, decapitations, and bisections. IMO, speed will be the biggest factor. Odin is much faster than Thanos. Factor in his combat experience and Thanos doesn't have a prayer.
skill shmill! With the way things are going, Odin will be headbutting people left and right and they'll probably have Thanos drop kicking everyone on sight.
