The Jimmy Clewes Set screw handle adapters provide a solid grip on any appropriate size tool shank. The other advantage of these units is that you are able to make the handles yourself out of most any wood, to your preferred shape and size and length. Then just replace blades in the future!.
These units are designed by Jimmy Clewes and made by Doug Thompson from high grade aluminium and are anodized in different colors for instant recognition of sizes.
This 3/8″ size accepts most all 3/8″ round shank tools.
