PAPERFOX RP-6 .. RP-20 CORNER ROUNDING KNIVES
You can round the corners of sheet materials with the Paperfox corner rounding knives. Individual sizes and shapes are available.
You can round only few sheets and the accuracy of the MP-1, MP-2 and KB-32 presses is not so good as for example the Paperfox S-3 corner rounder.
