What corner shape does it produce?
The K100 cuts an R4 profile, a 4mm half-radius rounded corner.

Where do the cut-off pieces go?

Usage and Care Tips

Slide the corner of the sheet fully into the cutting slot and keep it square before pressing, so every corner of a batch gets the same curve. Empty the waste tray regularly to stop scraps from blocking the slot. Keep the blade area clean and dry to maintain cut quality over time. The K100 comes with a 24-month warranty.
