Nice! That texture is because the blade is made of folded steel, and many years of light corrosion and/or cleaning with an acid, such as naval jelly, have "brought out" the layers. Lots of European swords of more or less this style; some-one else may pinpoint it for you. This is not likely a military sword, nor a ceremonial sword of any kind, but a personal self-defence/duelling weapon. This type of sword is often broadly referred to as a "side sword", and is known for use afoot or ahorse. My guess, and it is a guess, is that this is an 18th century sword. Nice.
BTW, I'm not advocating any actions, but just FYI it's highly likely (though by no means certain) to be a spring-tempered blade, with soft tang, and possibly soft forte.
