These USA made stitching chisels work great for cutting straight stitch holes in your projects. These are the chisels we use when planning the stitching layout in our kits. They are high quality, affordable tools.
We sell them individually or as a set of three. If your project has curves you will need to have the single, and preferably the double pronged chisel, in addition to the standard four prong. The one and two pronged chisels allow you to maintain your spacing, but also get into areas the four prong doesn't fit. The kits will call out which chisels are necessary.
Chisels are made with carefully tempered spring steel blades.
