By now you must have realized that Thor is extremely proficient with weapons and that has always been the case, as seen here when a young Thor easily schools a fellow Asgardian in battle.

Note: Sif is an incredibly skilled warrior in her own right as seen here when she easily bests Volstagg.

A drop kick to an opponent's face is always fun.

He Does something similar to Hercules.

Demonstrates skill when he adds Ulik's weight to his own for a toss.

Thor darts and weaves between Ulik's blows, then flips him.

Thor illustrates his superior skills against Masterson, leading to comments such as "Thor's dodging and weaving like a pro!" and "I can't seem to land a blow on him!".

The Absorbing Man believed that simply possessing all of Thor's powers made them equals, but he soon learned that was not the case, when Thor outfights him in moments using his superior skill.

"How can I fight 'Im? He's everywhere at once!!" is how Crusher Creel describes Thor who beats him down using his incredible fighting skills.

Thor might brawl like a brick against his peers in strength, but that is because he chooses to. When he truly gets ticked off and uses his skills, the fight gets one sided, even if his opponent is someone as formidable as the Juggernaut.

After their teammates were defeated, Thor and Hercules take on the Exemplars -beings who are peers to the Juggernaut- "in a display of skill and strength that rivals anything seen in Earth's long history." If they were not so outnumbered,"their centuries of experience" would have allowed them to win.

Thor once again shows what separates him from other powerhouses when he beats the utter shit out of an amped Loki and Fenris without letting them lay a hand on him.

The Man Beast was apparently an incredibly skilled individual, possessing the knowledge of every form of combat evolved by a million years, and Thor's fighting prowess still proves to be the superior.

Note: This might be a different Hercules from the one we are currently familiar with.
Captain America himself has described Thor's abilities as such: "He is an expert combatant; having been trained for hundreds of years in the art of war. His understanding of tactics and strategies encompasses the teachings of cultures over several centuries. Thor has shown himself to be proficient as a swordsman and in the use of his enchanted Uru hammer, Mjolnir."
