I'm starting to notice that some Artiest draw the scissor sword blade the wrong way.
I beg to differ, that's exactly how the half-scissor should look like. Look up other sources, or better yet try to visualize the other half of the scissors. The side that bears the 'hand guard' is the side with the scissor blade, I've seen some pictures that have it on the other way which is incorrect.
And though the blade isn't meant to be curved, I somehow prefer it this way.
