Tried to take a good picture. But you won't see it. It's just the inner edge which is filed down and they've used a black marker pen to cover it.
But it's a miss, the should have done this 45 degree angle at the handlebar clamp to.
It's like you pick up your stem, use a fine file and file an angle of 45 degree at the edge which is against the steerer tube.
You need no picture to understand i hope?

My camera is probably to crappy to pick it up good.

I guess because mine was later on, they contacted me and asked me if I wanted them to modify the original stem I had purchased or wait for the new design to come off the production line, which meant waiting an extra couple of weeks. Since I knew I'd be selling mine, I opted to wait.

i mounted mine in same hour that i received and forget of take a picture -sorry.. but the edges now is round (exactly as @PSM drawing) and no more 'cut' if you pass finger fast.
for all those don't feel safely with Hyperstem, i think the RoadstemOC model is a good option without much weight penalty (Hyperstem 78g - Roadstem 84g for 100mm)

I decided to skip weight savings at all cost. I also find Hyperstem a bit to soft (flexing).

Off topic, but this is what i like with the FSA K-Force Light BB 386 crank. The chainrings are super stiff, this makes shifting very precise.
What you read in the tests of cranksets, is just the stiffness of the crankset (not chainrings).
When chainrings are a bit soft, your risk losing shifting precision.
I try to keep a balance of low weight without selling out the performance.
Obviously, my Extralite stem was both damaging steerer tubes and handlebars aswell as being to soft.

I used it for several thousands of kms last year and checked the handlebars (carbon) & steerer (carbon) multiple times and didn't have a problem. Just be careful with the torque on the bolts and use a torque wrench.

That said, I've since replaced them with Kalloy Unos because the -7/-17 degrees are more up to spec with my position & bikes rather than the -6/-12 offered for the Hyperstem. They weigh a bit more (~25-30g or so) but I can live with that. I've been meaning to sell the two Hyperstems I have actually but haven't gotten around to it yet :x
