Splitting vertex in half

Some times I need to cut polygon starting from one of the corner vertex. But knife tool never seems to snap to a corner and leaves sliver of polygon. How can I make a clean cut from corner vertex?

Don’t bother cutting at the corner, just cut the opposite edge. It will automatically make cuts to any necessary vertices.

you can also merge the new vertex to the corner. select the on you want gone, select the correct vertex, press W > merge > at last

>just cut the opposite edge. It will automatically make cuts to any necessary vertices.

Ya that’s true, I need to try that.

>merge the new vertex to the corner.

In fact, that’s what I was doing. But its soo time consuming you know.
