Well, the three heads make it easier to block than a spear, as you can put your sword between the heads .It is maybe why they haven't been seen much on the medieval battkefields. I rather see tridents as a fishing 'weapon'. The simpler weapon is often the better one. I thought they used maces during WW1, not flails, you need to train a lot to efficiently use a flail, and a tranche is rather a small place, so the mace is better. The main fault of the bayonnet is you have to fix it to your gun, plus your gun is not a melee weapon, and so has a deficient balance. No perfect weapon exists !
