ToolKid fretsaw tensioner for changing fretsaw blades

The fretsaw tensioner is a perfect tool that children can use to insert and fix a new blade into the fretsaw by themselves. The clamp of the fretsaw shows a marking that indicates where the fretsaw tensioner for inserting or replacing the blades needs to go. The fretsaw tensioner also indicates that the teeth of the blade have to point down. The child can simply insert the blade and fix it by turning the wing nuts by hand. When you remove the tensioner again, the blade will have the right tension to saw properly!
