In brief: Sharp lacerations...

...Usually have smooth edges, which will facilitate healing; but if it's really long, you may need stitches even if it isn't deep.
You could also have a smoldering infection, even if the blade was "clean." and you need a tetanus shot if you haven't had one in 5-10 years. So you need to see your doctor.
