I bought that guillotine to cut up the back of books and scripts (first removing the hardcover if there is any, of course!) or to get a clean edge on the under side of scripts and books who where well used, so my fujitsu ScanSnap 1500m can better feed in the sheets.It works quite good, the cut is clean and straight. The plastic cap on the crank handle is made out of hard plastic and it was broken when I opened the packet. I repaired it with some glue but that piece is absolutely not necessery to work with that machine. Now I hope the blade lasts a long time! :)Off topic: The ABBYY OCR that is delivered with the ScanSnap 1500m is s***, it decreases the quality of the PDF. But thats no problem, juste use the OCR in Acrobat Pro 9, that is also delivered with the ScanSnap 1500m.
