Several customers have recently asked me which one of our corner rounders is the best. This question isn’t too hard for me to answer as I have been handling, using and selling corner rounders for 10 years. To start with, I can tell you hands down that Lassco and Akiles are by far the two most superior corner rounder manufacturers out there. Lassco is well known for its Cornerounder® line.

The corner rounder you use will ultimately depend on how many sheets you need to round, what you will be cutting and where you need to use it. Corner rounders come in desktop, floor model, manual, electric and pneumatic designs. For most corner rounding jobs, I would highly recommend the following models:

You would be amazed just how much round corners can affect the look of a document. Why is this? In part, it is because square corners are so common. Almost any sheet of paper, including magazine and newspapers, has square corners.

A round corner adds just enough of an aesthetic change to improve the appearance of a document. Sometimes it is so subtle that people feel the document they are handling is of higher quality, but the don’t know why.

What are some common documents to have their corners rounded? What I have seen, from our customers, is that many people like to round the corners of their business cards. A 1/8-inch corner is the most popular corner diameter. Photographs are also popular for corner rounding. So what should you look for in a corner rounder?

Be sure your corner rounder has interchangeable blades. For one, this allows you to swap out different diameter cuts. With this ability, you can use a 1/8-inch diameter on a business card and a ¼-inch diameter on a photograph. Most importantly, this allows you to replace a dull blade.

The handle length will determine how easy it is to cut through paper and material. The longer the handle, the more leverage you have and the easier it will be to cut through paper. Most of the corner rounders we sell at ABC Office can cut through at least a half-inch of paper.

Most corner rounders can cut through laminated material as well, however, laminated paper will dull the blade more quickly. Some of our higher end corner rounders can even cut up to .080 aluminum.
