You've probably heard the term "metal-injection molding," or MIM for short, in the last few years. It's a technique more companies are using in developing clubs, particularly irons, because it allows more precise forming and shaping.
Precision is what golfers expect most from their short-game clubs, especially their wedges. Now Cobra is bringing to market its King MIM wedges after a two-year effort.
What makes MIM better than forging for wedges, Cobra says, is reducing the reliance on a skilled machinist to grind and polish wedges by hand to get them to spec. With MIM, each wedge can be made using a mixture of 304 stainless steel metal powder, which is heated and then injected into a wedge mold. The metal is then sintered to 1340 degrees Celsius, hotter than a forged material, to offer even a grain structure that delivers even softer feel.
Once the mold is completed, a fully robotic polishing process finishes off the wedges to spec, with the goal of reducing variability in head weight and thickness, as well removing human error in shaping. The lone grind offered is dubbed the Versatile Tour, used by Rickie Fowler in his wedges, which offers extra toe relief for versatility across all short-game shots.
The wedge grooves and face are CNC milled in a radical pattern for precise groove shapes and maximum surface friction for ideal spin. Each wedge has a unique CNC milling pattern, with weaker lofts featuring wider, shallower grooves, while stronger lofts carry narrower and deeper grooves.
Each wedge comes with the Cobra Connect grip, made in tandem with Arccos.
The new Cobra Golf King MIM wedges will be available April 12 for $149 each in 50-, 52-, 54-, 56-, 58- and 60-degree heads in a chrome finish with the Versatile grind and a KBS Hi-Rev 2.0 125-gram shaft.
