Can IRWIN chisels be re-sharpened? If so, what's the best angle to re-sharpen at?
Since IRWIN chisels are one-piece solid-forged steel, they can be re-sharpened up to the last inch of the blade length below the tang. IRWIN chisels are ground by the factory at 25° and honed at 30°. The proper re-sharpening angle is 30°.
