He used a bladed knife

He also didn't consider Zoro a "worthy" opponent till later

In Marineford he used Yoru on everyone including fodder

GB fought King and Queen + the Revo commanders while "struggling" (he wasn't I know) with the latter and still chose not to use his sword
And Ryokugyu used Stabbing techniques like one would use with a blade.

And Rev commanders he was just holding back the giant not trying to actually defeat him because causing any collateral would be a death sentence. Hence why you’d use the giant form to restrain the giant while the CDs left
