It also brings up another question. Are you talking old school blade on blade fights? In effect dueling? If so, this has been relegated to the studying of various arts with blades made specifically for that purpose. Take the Crossada. If I wanted a dueling knife or a knife to fight an equally armed opponent, thats it. Its heavy, got lots of reach, has a sharpened back edge, and the screw in side quillons mean four sided hand protection and the ability to trap and remove an opponents blade. A bowie like the Hells Belle excells at this also. For the chance encounter on the street? Very few people want fo fight an equally armed opponent, even hardened criminals rarely want a fight. For this, violence of action and agressiveness will mean more than what blade your holding. A box cutter, steak knife, or other cheap throw away would be my choice here. Sharp and pointy enough to carve someone up, then bleach it and toss it. No money lost and it did its job. This is all just my opinion of course, its worth what you paid for it
