The Sigma Series 4 Up 70 cm works by pull scoring: the operator draws the handle toward themselves rather than pushing it. That action gives more control on common formats and suits work in tight spaces, where there is no room to push.
Its 12 mm scoring wheel stays constantly visible on the operator side, and its CNC-machined holder eliminates lateral play for a consistent score.
