So a while back, I've heard some commotion about the Falchion and the tyrfing looking the exact same sword via appearance, so what I did was that I took screenshots of the swords from heroes, cropped it, made a collage, and did an analysis with a friend of mine in class at school, and so this is what me and him saw:
Why does the Hilt of the sword look the exact same?
Actually, it doesn't, on the Falchion, you can see that on the very edge of the hilt or what it's called, it is very cut, but on the tyrfing, it's not, it's fairly sharpened
Why is the gem in the middle the same gem?
Actually, it is the same gem, but as you can see the color varies, sure it's the same color, but the color scheme is different, on the tyrfing, its a little darker, but on the Falchion, it's a little brighter
Remember, each blade is created differently and named differently (except the pararlell Falchion and Chroms Falchion) but yeah, that's all that I found on the two swords, I hope this analysation helped clear everyone's questions on why the swords sorta look the same.
