Bernina Buttonhole Cutter

The BERNINA Buttonhole Cutter with Wooden Block is a precision hand tool designed for cleanly opening finished buttonholes on garments, coats, and home décor projects. It replaces scissors with a purpose-built chisel-style blade that cuts straight and true every time, protecting the bartacks and beads of the buttonhole from fraying or distortion. Whether you sew occasionally or produce finished garments regularly, this tool delivers a professional result with minimal effort.

Key Features

• Chisel-style blade cuts cleanly through buttonholes in a single, controlled press — no scissors required.
• Wooden block is placed beneath the buttonhole to protect the fabric and provide a firm cutting surface.
• The 13 mm (½ inch) blade width is sized to fit standard buttonhole openings accurately.
• Blade is centered between the buttonhole beads, cutting through without disturbing the sewn edges or bartacks.
• Minimal pressure is needed to cut through most fabric weights, reducing hand fatigue and the risk of slipping.
• Precise blade design prevents fraying at the cut edges, keeping buttonhole openings neat and durable.
• Compact and easy to store alongside other sewing tools in any workspace.
• Compatible with buttonholes sewn on BERNINA machines as well as other brands.

Frequently Asked Questions

What is included with the BERNINA Buttonhole Cutter?

The set includes the buttonhole cutter chisel and a wooden block. The wooden block is placed under the fabric to support the buttonhole while you press the chisel through from above.

Do I need a BERNINA sewing machine to use this tool?

No. While this is a BERNINA-branded accessory, the buttonhole cutter works with any finished buttonhole regardless of what machine was used to sew it. It is a manual hand tool that requires no machine attachment.

What size buttonholes does this cutter work with?

The blade is 13 mm (½ inch) wide, which is sized to fit standard buttonhole openings. It works best when the blade is centered between the beads of the buttonhole and pressed straight down onto the wooden block.

Will this tool damage the edges or bartacks of my buttonhole?

When used correctly — with the blade centered between the beads and pressed firmly onto the wooden block — the cutter slices cleanly through the fabric without disturbing the sewn edges, beads, or bartacks.
