Description

Mizuno MP32 3-PW Black Nitride Forged Muacle Back Blades Professionally Refinised.  Auction is for professionally nitrided USGA compliant heads. Miura and sub 70 do this finish on special order. Raw, rust proof black metal with awesome west resistance.
DM if you need paint fill or install to your specs. I do custom builds with frequency, MOI tour style matching for equivalent release and contact angle.
More on nitriding:
This is the absolute best finish you can put on a golf iron for feel, consistent spin/launch, aesthetics and glare removal. You’ll be playing with a satin, rust proof bare steel that’s dent and gouge proof.
1.  Nitriding is a metal finishing process where the chrome is stripped off with the head polished down on the bare metal.  The head is then soaked in a molten cyanide salt at 800C which darkens the head to a rust proof black finish.  This process does two things in that it provides a light swell to the outer metal forming a satin/matte finish and super hardens the metal.  The black appearance is not an outer surface coating (oxide) it is the metal itself as it's impregnated deep into the outer steel layers with nitrogen meaning you have to wear thru this layer of steel before it looses it's appearance appearance.
2.  Nitride provides a very hard metal but soft iron.  Softness arrives when you remove low friction chrome.  The natural steel even though super-hardened provides a higher friction surface and with the satin/matte appearance brings friction levels even higher.  This friction on ball compression holds the ball longer on the face allowing it to soak further into the grooves before it travels up the club face providing advanced spin and ball flight.  You will also see white impressions on the face where the ball was struck giving you instant feedback on your ball strike.  This white impression is the balls coating pulled off by friction forces.  Nitride is the only real process which does this efficiently.  Copper for example has great friction dry but poor when wet.  DLC and oxide black coatings should be avoided for other reasons and are not quality finishes.  Raw steel is great but rusts so it's aesthetics are bad and gouges easily.  Also without the black appearance you cannot visualize a ball strike on raw steel.  Club manufacturers in Miura and Sub 70 use this process on special orders if you need a point of reference.
