This is the PLUS PK-513 paper cutter. While the successor model, the 513LN, uses disposable blades, the original PK-513's blade can be sharpened. You can have it sharpened by a professional for around 3,000 yen (replacement blades cost about 20,000 yen). Also, unlike the 513L which uses LED lighting for the cutting area, the 513 uses a light bulb, making replacement easy. Overall, this model is designed for long-term use. Although there is some wear and tear, both the blade and the blade receiver are still in good condition. Instant purchase is OK. Here are the features of the PLUS PK-513: Popular for self-scanning books (cutting the spine of a book to convert it to PDF) and for cutting large stacks of paper due to its sufficient cutting capacity. Compact and doesn't take up much space, making it easy to handle on a desk or in a small workspace. It's a handle-operated model, so no power is required, and the operation is relatively simple. The cutting surface is highly accurate with minimal misalignment, meeting the needs of those who want to "align the cutting surface" and "cut cleanly."
