What do you do when your 45mm rotary blade (with wedge center) becomes worn down? Don't throw it away! Install it in the BladeSaver Thread Cutter instead. This small but handy device repurposes used rotary blades into a convenient thread cutter for chain pieced fabrics.
The magnetic case holds the blade in place for ease of use, and when you are finished, you can tuck the blade safely away inside. They are available in three fun colors! (GREEN NOT YET AVAILABLE)
