Gask
Silver Baron of the Realm
He does it to make opponents drop their guard so that he can take advantage of rash behavior and then lash them to various things. He still ends up using it for every truly challenging fight though along with the lashings.No, if I recall, he drops the shardblade on purpose before killing a bunch of guards (I forget which ruler he was going after). I think he may have also thought that killing without the shardblade was easier/better.
