Standing at the bar with a guy you used to call your friend. You put your long haul on the counter while you rummage through your coat for a nic stic.
When you look up, your long haul is gone.
This asshole just palmed your long haul.  You pull a knife
And pretend to be a sewing machine while you scream obscenities.

I want to make a melee character that dual wields daggers, knives, rapiers, something stabby, with a lot of attacks per round.

How best would I achieve perforating my opponent -nd making his holes numerous?

I want a cyberhand with a jackhammer attachment that I can put a blade on.

Extreme cyber-implant weapon

And there is no D&D 3.5 mechanic for multiple attacks: You get one per combat phase, no matter how many hands you have.

There are rules of dual wielding under Martial art and they are pretty good, they are in Run & Gun. I would stick to those, they aren't very complex and they offer some decent bonuses.

Okay, so we got Initiative Passes and Combat Turns. In an Initiative Pass, you are only allowed 1 offensive action. Melee also is Complex to begin with, so doesn't matter. You can take the Multiple Attacks action, but that involves splitting the dicepool. So there's 2 things you need to execute a lot of attacks.

1: High dicepool count, so the split doesn't hurt too much.
2: High initiative.

Now sure there's initiative-boosting powers and gear, but a cheaper way is Edge. Just grab whatever Intuition and Reaction boosts you can get (Mystic Adept with combat-stats and Quickening for Increase Attribute spells is the most solid way but requires at least 8 karma after chargen and 7 kept during, an alternative is Resources A, Attributes B, +2 very expensive Intuition, +3 Reaction ware), then spend Edge to roll 5 Initiative dice.

Remember that combat rules are an abstraction. If you shoot someone with an assault rifle on full auto, it's just one attack test and one damage resistance test no matter how many bullets are involved. Melee combat works much the same way. You attack with a blade, the target defends and soaks the damage. Depending on the result, the GM might say "Your knife traces a thin red line across his arm" (one box of damage) or "You drag him across the table and stab him repeatedly" (ten boxes of damage).
