Dude, you're being a little aggressive for someone who's completely wrong. This is literally the first description of the sword in TEoTW.
> Slowly Tam drew the weapon; firelight played along the gleaming length. It was nothing at all like the plain, rough blades Rand had seen in the hands of merchants’ guards. No gems or gold adorned it, but it seemed grand to him, nonetheless. The blade, very slightly curved and sharp on only one edge, bore another heron etched into the steel. Short quillons, worked to look like braid, flanked the hilt. It seemed almost fragile compared with the swords of the merchants’ guards; most of those were double-edged, and thick enough to chop down a tree.
Eye of the world, chapter 5.
In case you don't know, a quillion is another word for a crossguard.
There's also the newspring graphic novel.
The traditional version from the novels:

And then, once upon a time, there was the authorized Museum Replicas version of a Heron Mark sword, with a different (but valid) interpretation of a heron mark on it:
Mine is this one, technically it is not accurate as the herron is not also inlaid in the hilt(important for the prophecies) https://www.amazon.com/Museum-Replicas-Officially-Licensed-Wheel/dp/B00421A4FO
This is a much better one but it does cost 100x more: http://www.fableblades.com/TamsSword.html
As long as posting an Amazon link (I'm not an affiliate, and these have been out of stock for years) won't get me scolded?
They have these "officially licensed" swords already. I read somewhere that they were ok'd by RJ himself.
Very nice detail! Though I would not have added the text personally.
Hmm found out you can buy replicas on Amazon
