How to Use Buttonhole Scissors?
Buttonholes are essential functional elements in garment construction, designed to allow two pieces of fabric to link securely together using buttons as fasteners. Since buttons come in various sizes—ranging from 10mm shank buttons to 25mm flat buttons—creating properly sized buttonholes is critical for both aesthetics and functionality.
Buttonhole scissors rank among the most efficient tools for cutting buttonholes. The technique is straightforward to master and delivers cleaner results than seam rippers or regular scissors. Professional tailors have relied on buttonhole scissors for decades because the adjustable blade mechanism produces consistent, precise cuts every time.
A properly constructed buttonhole lies completely flat against the fabric without gapping, tearing, or stretching. Standard buttonhole lengths follow industry conventions: shirt buttonholes measure approximately 3/16 inch to 1/4 inch (4.8mm to 6.4mm), while jacket buttonholes typically span 1/4 inch to 3/8 inch (6.4mm to 9.5mm). Using buttonhole scissors incorrectly results in torn edges, ragged openings, or holes sized improperly for the intended button.
Other Types of Buttonhole Cutters
Creating a professional buttonhole requires both the appropriate sewing machine setting and the right cutting tool. Several types of buttonhole cutters exist in the tailoring industry, each with distinct advantages and limitations.
Seam Rippers
Seam rippers are popular budget options for cutting buttonholes. These tools feature a handle attached to a sharp pointed blade with a curved cutting edge. The user inserts the pointed tip into the fabric, then pushes the curved edge forward to cut the required length. However, seam rippers offer minimal control over cut depth and direction, making them prone to slipping and damaging surrounding fabric.
Standard Scissors
Using standard scissors to cut buttonholes is the least recommended approach due to significant safety risks and precision limitations. Scissors provide no mechanism to control cut depth, and the user must manually follow a marked line—any deviation results in an uneven buttonhole. Additionally, the scissor blades may push and distort the fabric weave rather than cleanly cutting through individual threads.
How Buttonhole Scissors Work
Buttonhole scissors operate through a dual-blade mechanism where the handles manipulate a pair of cutting shears, similar to the action in precision rag quilt scissors. The primary distinction lies in the adjustable guide screw located near the pivot point.
This adjustment screw controls the maximum blade opening, effectively setting the precise length of the cut. Most quality buttonhole scissors offer adjustment ranges from 2mm to 50mm, with the notches on the adjustment screw providing 1mm increments for fine-tuning. When the screw is set to a specific measurement, the blades stop at exactly that opening width, ensuring every cut matches the previous one.
The notched guide rails on the scissors’ body hold the fabric flat during cutting, preventing the blades from deviating horizontally and creating the sawing effect that damages fabric. This guide rail system is what separates buttonhole scissors from regular scissors—the notches keep cuts perfectly straight along the fabric grain.
How to Use Buttonhole Scissors
Using buttonhole scissors requires less technical skill than sewing a buttonhole on an vintage sewing machine. The procedure breaks down into five distinct steps, each critical to achieving professional results.
Step 1: Determine Buttonhole Length
The most critical measurement comes first. Measure the button’s diameter (not including the shank) with calipers or a ruler. Industry standard adds 1/16 inch (1.6mm) to the button diameter for the buttonhole length—this small allowance enables the button to pass through without excessive tightness or looseness. For example, a 15mm button requires a 16.6mm buttonhole.
Step 2: Mark the Buttonhole Position
Using a fabric marker or chalk, mark the exact starting point and ending point of your buttonhole along the fabric grain. Place the button on top to verify the marked length matches your measurement. This verification step prevents the most common error: cutting the buttonhole too short.
Step 3: Set the Adjustment Screw
Loosen the adjustment screw on the scissors and set the blade opening to match your measured buttonhole length. The notched scale on most buttonhole scissors provides clear millimeter markings. Tighten the screw firmly before proceeding—the screw must not shift during cutting.
Step 4: Position the Scissors
Open the scissors fully and place the bottom blade beneath the fabric, ensuring the notched guide rail sits flat against the fabric surface. Align the starting notch with your first fabric marker. The top blade should rest directly above your marked cutting line.
