Very simply, “smash factor” defines how efficiently energy is transferred from the club to the ball at impact. The best illustration of this can be found in a simple carpenter’s hammer. Used properly, it puts maximum mass right in line with the nail. But if you turn that hammer on its side, it loses all that efficiency. Why?

It’s the same hammer, swung by the same carpenter… but on its side, the mass to either side of the impact point with the nail, so smash factor is severely deteriorated.

In your wedge play, impact efficiency is affected by how much mass is directly behind the point of contact with the ball. Since distance control is what wedge play is all about, the goal is to have the smash factor as consistent as possible across the entire face so your not-so-good shots turn out more like your best.

You’ll quickly see and feel the difference in face thickness between an EDISON 2.0 wedge and any other wedges.

“Gear Effect” is also completely determined by how the mass is distributed around the club head. In drivers, the “holy grail” for optimum distance is high launch and low spin, and the engineers get that by putting as much mass as possible in the bottom of the club head so it is below the point of impact.

But in your wedge play, your goal is exactly the opposite – you are seeking penetrating ball flight with maximum spin. That requires more club head mass above the actual point of impact on the face, so gear effect can be optimized for those two objectives.

In this illustration, elite players have learned to hit wedge shots at “A”, almost “blading” the shot, which puts most of the club head mass above the point of impact to optimize gear effect. But when impact moves up just a few grooves to “B” (where you likely hit your best wedge shots), other wedges are dramatically thinner, more mass is below the point of impact, and gear effect is severely reduced.  Your most common misses -- slight high in the face or toward the toe (‘C’) causes a loss of another 10-12% of efficiency.

You probably didn’t know those huge losses are actually built into all mainstream wedges, even those that claim to be “game-improvement” design.  So, unless you always hit your wedge shots at center face and on the 3rd or 4th groove, you’ve never gotten anywhere near optimum efficiency and your slight mis-hits have been unfairly punished.

We find that completely unacceptable.

Every EDISON 2.0 wedge incorporates the patented Koehler Sole, and it’s hard to find a lie this sole doesn’t like or a swing path it can’t handle. Instead of making you compromise with some specialized grind, the Koehler Sole combines a high bounce angle in the front of the sole with a low bounce angle in the back of the sole so you can forget all that B.S. about bounce and grind… and just hit the shot with confidence.

If your swing is steep or you play in soft conditions, your EDISON 2.0 wedge will perform like a high-bounce design. If your swing is shallow or you play in firmer conditions, it will perform like a low-bounce wedge.

So, no matter what shot you're about to hit or where you're playing, you'll always have the right wedge in your hands.

A wonderful side benefit of our ultra-high center of mass is that it creates more spin, particularly on those mid-range wedge shots where you don't swing as fast.

Thousands of golfers can attest to the fact that EDISON technologies deliver what we are all seeking – spin that can stop a ball in its tracks. And because the EDISON 2.0’s unique design mitigates spin loss on off-center impacts, the spin on your slight mis-hits will surprise you.
