I just had to put this quote from Sollima about La resa dei Conti in the Interview Novecento showed me, I do not if anybody else as read it, but coming from the director itself it’s just fantastic
MM: Resa… was different also from the point of view of introducing what the Italian newspapers called the political western. The character of Cuchillo is totally unprecedented in western cinematography, even in the american one. He fights with a knife against firearms. He points at the hyprocrit behaviour of the rich and powerful with few, piercing sentences, coming from the intelligence of a hunted human being who must simply survive, day by day.He is able to rock and shake the iron moral beliefs of Johnatan Corbett, who does things because he believes in the law. Cuchillo tells him …which law, the law of the one who chases or of the chased?.
SS: James Coburn uses a knife in Magnificent Seven, but it has a totally different and tactically limited meaning. Cuchillo uses a knife because he is a proletarian, he is too poor to buy a gun and ammo, in fact he does not want to be armed at all. He says in a certain scene, he would much prefer to use a knife to cut bread…! So the knife and Cuchillo bring a whole new view of the western myth into play, the one of the really poor, the forsaken, the people with no choice. In reality he traces an image of those who did not sustain the myth of the Wild West, on the contrary, Cuchillo abates the myth itself! And he triggers, symbolically, the crumbling of Corbett´s firm beliefs in a social order, in the law, in a cast-oriented structure of society, in the honesty of the wealthy in pursuing the “benefit of Texas”.
