It has probably been a thread about this before, but as I've never seen one I'm bringing it up. At the point when Triss and Geralt are having sex beneath the roses of rememberence some Scoia'Tael walks inn and notices that the bandits have been killed by a witchers blade. How can they notice this and not notice that Ciaran and his unit was attacked by a witchers blade, and assume that it was Loredo's soldiers who did it?

Maybe Letho used his daggers to kill them, like on Demavend's boat?

or

Maybe now they know what a Witcher blade cut looks like after being informed of how Ciaran and his unit died.

The daggers would make sense, but if they learned from Ciaran's unit's death they would have to know that a witcher killed them and they do not

In the books a "Witcher's blade" is defined as a longsword forged out of meteorite - lightweight, thin and sharp as a razor yet nearly unbreakable. It is implied that Geralt always carries one. Victims look like they were sliced with a giant razor - it's how Geralt figures out the dead Salamandra thugs in TW1 swamps were killed by Berengar.

However, the big heavy longsword Letho uses during your first bossfight is an ordinary Temerian blade - not to mention that Letho, knowing he must maintain his charade, could have simply hacked the elves to pieces instead of using distinctive Witcher slashing techniques.

Letho has different fighting style than other witchers. You can read it in his companion journal that you can find in ACT2.

True I forgot that happens before meeting Iorveth. He probably used the daggers anyway as Letho only seems to use his sword for duels. Plus he wanted a surprise attack the daggers are quicker and stealthier and good for groups, as seen on Demavend's boat. Also he could have used daggers because he knew the Elves would recognize a Witcher's blade ha.

As Ciaran survived, I doubt he hacked them to pieces. But that he carries a longsword sounds reasonable, but Geralt doesn't have a typical witchers steel sword either?

But does that affect what kind of traces the sword leaves after a cut?

Well spotted! Here are his companion's notes from the wiki:

Notes of the kingslayer named Serrit
He seems different, but in reality is so similar. Our paths have been the same: we survived the Trials, endured the same training and have slain so many monsters that we no longer keep count. So many men, also. The difference is in the details – when I see him moving in combat, I want to laugh, but I also see that he is just as effective, if not more so. There is, however, one critical difference I cannot describe adequately. He has a goal, he is committed to something. He doesn't wander the world as if blown about by the wind. I believe he feels emotions at a level I cannot attain, yet these emotions are not typically human. Is it an illness of some kind? I think he teeters on the brink of instinct and emotion, and that he uses up a lot of energy to maintain his mental health. I hope I get a chance to know him better and learn from him. Nothing specific – just life.

Although it can be interpreted in another way. The Viper school clearly teaches dual-wielding - which no other school does, - yet Letho fights with a single heavy blade. Perhaps that's what Serrit finds "funny yet effective" about his style?
