What type of hook is used to hold the ends of two pieces of canvas being sewn together?

The sailmakers or bench hook is specifically designed for holding the ends of two pieces of canvas while they are being sewn together. This type of hook is an essential tool used when working with canvas, as it securely grips the material, allowing the sailmaker or seamstress to sew without the pieces slipping or moving out of alignment. This stability is crucial when achieving strong, long-lasting stitches, especially in marine applications where durability is paramount.

Other types of hooks mentioned are used for different purposes. A snatch hook is typically used in conjunction with a line to provide a quick connection but does not offer the stability necessary for sewing. Swivel hooks are commonly used in rigging and for connecting components that require freedom of movement but are not applicable for sewing fabric. Clip hooks are generally designed for quick attachment and detachment of gear and are also not suited for the precise work of sewing canvas.
