Black oxide is a chemical dip for metals on carbon and stainless steel. Black oxide is a durable finish for those looking for protection against chips and dings along with rust and corrosion from chemicals found on the greens. Black oxide can be finalized with a matte or satin. (Polished finish upon request/custom order.) Includes removal of dents and scratches, stripping of previous finishes, if needed, CNC face milling and color fills up to four colors. We suggest bright colors which stand out against the dark black and make your putter pop. This putter requires less maintenance than an oil can but will still need to be kept dry and oiled after use.
