I used stainless steel 303 0.375 inch diameter and 1 inch diameter rods to make a 24 inch long fireplace tool for our wood burning fireplace. We live about one block from the ocean and it seems that everything rusts or corrodes if it is not made from stainless steel. The fireplace handle has a knurled finished with a 21 a cross diamond pitch and is slightly larger than 5 inches long by 0.7 inches in diameter (actually machined down to 0.693 inch diameter for a perfect fit for this type of 21 pitch knurl – see Smartphone Android app “Knurling Calculator” for calculating the diameters) .
