Not arguing with anyone else's methods, but I do it a little differently. I cut into the corner as anyone else does, then I pull the blade back a little, 1/2 inch or so depending on the pattern, and put a little side pressure on the blade and cut back into the corner. I'm very careful about stopping on the line. This opens up a little wedge shaped cut and I can pivot the work and start my next line. Not saying its the correct way to do it, but works for me.
