KUTSUWA STAD T'GAAL Angle Adjustable Pencil Sharpener, Translucent Black, 1 ea. (RS036BK),Translucent Black

I plan on sharpening soft core colored pencils. Does it matter what setting i use? My goal is to avoid lead breakage. Thanks.

Please, what are the 5 different angles? I need 30 degrees.

But does it sharpen the thicker pencils, like polychromos and derwent?

Are there any other sharpeners (hand crank or electric) that can deliver the shorter, sturdier tip that Setting #1 gives?
