Amazon.com Product Description

A must-have for hanging doors, this spring loaded corner chisel is more efficient than a hand chisel, and works quickly to ensure that corners are perfectly square. Compact enough to carry in your pocket, with a 3/8-inch cutter edge, this handy tool creates a 90 degree square corner when simply placed on any corner and tapped with a hammer. And because the Porter-Cable 42234 Corner Chisel self-aligns, accuracy is never an issue; you get the right fit every time with minimal maneuvering.

5.0 out of 5 stars A Must-have for door hangers, November 18, 1999

By A Customer

If you do any door hanging, this is a must have. Many commercial hinges, bolts, etc. have square corners. Often, even doors mortised at the mill shop come with rounded corners. I would never be without a corner chisel, and the Porter-Cable is the best I've used. At less than twice the price of the lesser-quality imports, it outlasted 4 of them so far. Definitely worth the price.

After reading mixed reviews of the corner chisel I ordered one anyway. I am a contractor specializing in finish work and it seems like most of the door hardware I use lately is square cornered. The tool works good at cutting and it usually removes the chips at the same time. Sometimes you just have to lift the chips out of the corner after they are cut. The only drawback that I found was the striking surface is rounded and can cause the hammer so slip off after hitting it. But the corner gets chipped out anyway, (I just hit it with the flat side of my hammer). If I was doing production work I would probably modify it to give it a little bigger footprint for more stability, and a longer body for better grip, and a longer stike to keep the hammer away from your hand. Overall, for a pocket tool, it is well worth the cost. I wish that I had ordered one years ago.

When I first looked at this I thought, "How can it know the exact corner?" But it does. When routing out a template guided area for example, leaving a rounded corner, you park this in the corner, one decent whack with the hammer, and to my surprise, a perfect corner. It is a very simple device. It's a 90 degree blade that slides along a very thin outer shell-guide.
No more chisel-chisel-chisel, and difficulty getting the exact angles. It works as advertised. Saves a lot of time, and does a superb job. Highly recommended.
