Replacement handle for the Knew Concepts saw frame is available in 2 sizes, medium and large. We are completely out of our cocobolo supply, all handles are now available in Mesquite. Note: Titanium frame saws have a bit of variance in their thickness, slight filing of the ferrule slot may be needed for proper fit. This handle is designed to fit saws with a frame thickness of 1/8". It will not fit the newer Mark IV Heavy Duty Fret saw since it has a thicker frame closer to 3/16. Please order the handle designed for the Mark IV or Coping saw if you have either of those saws.
