Eh, I can sympathise. Apart from the knife I've been in similar situations at school. It doesn't matter really how big the either of you are, the wolfpack type dominance thing runs deeper than just physical traits (besides, if they're small and wiry, and you're more doughy, they could probably still kick your ass). There's a whole lot of attitude and confidence involved too. And if there's a couple of them working as a pair, that's harder to effectively kick against.
Until of course your ability to block the twats out is exhausted, you snap, and deliver a wholly unexpected and purely adrenaline-fuelled beatdown, possibly involving nearby furniture, that gets the whole group of you a trip to the headmasters office and a thorough talking to, including an Ed Psych and parental involvement.
I managed to avoid the suspension, but maybe because I didn't actually have a weapon (having put my contraband 2-3ish inch flick pocketknife away in its drawer following the evaporation of a regular potential mugging threat on the way home when a particular local character moved schools and the street lighting improved), and there was others' candid confirmation that they'd been ripping on me a good while. Funnily we ended up sort of friends not that long after, in some wierd Dragonball Z (or again, wolf pack) kind of way.
If he's pulled a blade on someone, staying away until it's all calmed down may be for the best, because someone else may then come at HIM with a weapon in retaliation...
Oh ... and something I noticed in my later years at school ... something changed with the Playstation generation, like a switch was flipped. The incoming youngsters were a lot nastier and harder to deal with all of a sudden. Like, in the 3rd or 4th year, the 1st years were OK, went about their business, often cheeky/annoying/argumentative but would usually do what they're asked. 5th and 6th? Bad tempered and antagonistic savages (whereas those who had moved up a year or two were still alright). Seriously, WTF. I really wouldn't have liked having to deal with a Y7 who had it in for me whilst I was in Y10/11, though actually beating up someone several years my junior would require an exceptional amount of harrassment.
