It’s inevitable that chisels and planes will need re-sharpening with use. All you will need to do this is an oil stern and a can of household oil. Apply a quantity of oil to a stone. With a gentle grinding action, the sharp end of a tool can be renewed. Make sure there’s plenty of oil on the stone so as to stop any abrasion of the metal. Smooth off the back edge of the chisel and the sharp edge should be ready to be used.
Sharpening a plane is exactly the same but make sure you familiarize yourself with how the plane comes apart. Sharpen the plane blade on the oil stone. Smooth off the back edge as with the chisel and don’t forget to remove any excess oil off the blade.
