Almost no cost burnisher.
materials: used automobile valve. In this case an exhaust valve from a Toyota racing engine. Free no cost.
short piece of emt conduit for the ferrul. Scrap from trash. Free no cost. A piece of scrap poplar for the handle. No cost. Enough epoxy to glue the valve stem into the handle. Not much cost. Finish for the handle. Not much cost. Sandpaper. Not much cost.
procedure: cut the valve end off of the valve. The valve end is not as hard as the stem. Cut a short piece of the emt for the handle. Drill a hole in one end of the handle blank. Turn the blank to shape between centers and finish. Glue ferrul and stem into, onto, handle. Sand ferrul on lathe just for beauty
that's it.... Cheap, easy, effective...
just a heads up on choosing the valve... Some valves have sodium in the stem to help cool the valve. You must not cut into a sodium cored valve. Liquid sodium burns in contact with water. Or so I've heard. No experience with that. Rumor...
this valve is stainless steel. It is hard enough. Regular valves may be harder.
enjoy!
