And the rapier isnt Iconic?
That isn't the point I was making with scimitars being iconic. The word "scimitar" is used
instead of the words "curved sword", because the scimitar is so iconic that those two are almost interchangeable.
There is a mechanical difference between a rapier and a generic sword [...] It would be a sword for stabbing instead of slashing
That's not a significant mechanical difference, they are still used the same way, generally speaking. You slash, you stab, you bash with the hilt. Introducing something that just specialises in one of those but still uses them all isn't significantly mechanically different.
We have halbards that are different from pikes and have both.
They are significantly mechanically different. A pike is to the spear what the two-handed sword is to the long sword. The word halberd is often used to reference any and/or all
non-spearlike polearms, such as billhooks, poleaxes, glaives, e.c.t. and this is shown in game as it is classed as an axe rather than a spear.
we have morning stars which are different from maces and have both
Being sharp, rather than blunt, is a pretty significant difference.
And rapiers are ubiquitous in fantasy
That's irrelevant when all weapons are generalised. Greatswords are also ubiquitous in fantasy, but they are lumped in with every other really big sword.
its probably more iconic then a scimitar.
I very much doubt it, and again, that isn't the point I was making about the scimitar.
I'd love to see rapiers as a sidegrade to shortswords for dorfs.
I'd say it'd be more of a longsword sidegrade, with
smallswords being the sidegrade to shortswords.
Having looked them up on wikipedia for that link though, they're both post-1400s, which definitely doesn't bode well for them being included in vanilla.
