Reduce time working, add value to your home.


Crown moldings are one of the architectural features that can really add value to a home. They add a visual presence that can make a home feel more upscale.

Done well, a home looks well-crafted and solid. It brings a sophistication to any part of the house and nothing dresses up a room or cabinet like the presence of crown molding.

Mind the gap, but let the Onecut take care of it.


Installing crown molding has until now been a task that strikes fear in the heart of every amateur carpenter—and even some professionals.

Cutting compound angles and keeping track of inside and outside corners, all those splices and the molding’s various orientations has been such a nightmare.

With the Onecut, those nightmares are none of yours.

Cut like a professional carpenter in less time than calling one.

Both amateurs and professionals who are looking for a seamless way to take on crown molding installations will enjoy the Onecut.

It makes no difference whether it’s an outer angle or an inner angle you have to measure. Keep your Onecut up against the saw after measuring, and get that precise cut down to the last millimeter.

It will save you time and money through less scrap and guesswork. No calculations, no complicated settings, no more trial and error and no more ugly gaps in crown molding joints. One cut is all it takes.

A lightweight tool with exceptional build quality. ABS plastic for the win!
