you think spiderman could take a slash to the arm and just keep coming? (scratches head) hmmmm. assuming that sabretooth doesn't even hit any nerves rendering spidey's arm completely useless, he still as a low probability of using that arm in the fight again. Spiderman could barely fight when he had a sprained arm, a slashed up one isn't going to do him any good. Spiderman may have his spider sense and he will be able to dodge some of the punches but not all of them. I mean he took a pummeling from the vulture and the vulture's an old guy. If wolverine surprised spiderman with his speed and even made spidey second guess himself as being the faster of the two, and sabretooth is faster than wolverine, i really don't know how much of a factor spidey's speed plays into this. Hie strength either, someone said he'd cave sabretooth's face in which is just retarded. Wolverine can stand up to class 60-100 punches with ease. Sabretooth may be in a 3 to 5 ton range, possibly even more, but nevertheless even if sabretooth is 3 times as strong as wolverine and has a faster healing factor with an adamantium skeleton spiderman's punches ain't doin nothin to sabes.
Spiderman's webbing isn't always unbreakable. A battle fatigued venom got covered head to toe in spidey webbing and broke completely free of it in a matter of a minute or so. I'm not implying that sabretooth can break free of the webbing himself, but the webbing isn't indestructible.
Once again, it all comes down to whether or not spidey can web sabes in such an uncomprimising way that sabes won't be able to break free. Considering that sabretooth won't just be standing there taking it I would say it could go either way, but in a straight up brawl spiderman will lose.
Aside from KOing rogue in 3 hits (I doubt spiderman could knock her out in 3 blows), crummpling an iron curling bar into an rion shotput, uppercuting logan 3 stories into the air, lifting and tossing cars, nearly killing killpower (who sports hercules level strength, superhuman speed and agility and a healing factor himself), and turning wendigo into a fur coat, other exapmles of sabretooth's strength include him pushing through a forcefeild that was strong enough to hold back a full grown raging elephant, and ripping shiva's head off with his bare hands, who's armor is supposedly second to adamantium only. Unless spiderman can properly restrain him with his webbs all this is gonna be is spiderman dodging and weaking for his life.
