This is a rotary high quality carbide Scoring Blade made for the Scor II Perforating/Scoring Machine manufactured by Lassco Wiser. This blade will fit both the 19-1/2" and the 25" capacity units sold under our Order No PP0470 and PP0466.
This blade is used to 'score' (emboss a narrow ridge into) the paper. This is done both to reduce or eliminate cracking and produce a precise fold line (register) that reduces stress to the paper and permits a crisp fold. (Old P/N PP0473)
