Specialty Tool: The Trend Corner Chisel Quickly Squares Hinge Mortises

For those who prefer routers over chisels

By Rain Noe - September 25

With a sharp chisel, a skilled carpenter can create a hinge mortise in less time than it takes to set up a router and jig to do it. That said, there are still those who prefer to perform the task with a router, and this presents a problem if installing hinges with corners. Since router bits are round, they can only create mortises with rounded corners.

British tool manufacturer Trend Tool Technology invented their Trend Corner Chisel to remedy this.

It's a spring-loaded corner-shaped steel cutter suspended within an aluminum block.

You square the body against two adjacent edges of the mortise, deliver a hammer blow, and voila.

The tool runs $31.

But there are hinges with rounded corners, usually 5/8" or 1/4". They're usually the same price as a square-cornered hinge or within a few cents. It feels to me that an old-school carpenter would just use a chisel correctly and a less-skilled or newer carpenter would just use a router and widely available pre-made door hinge jig.
