Here's what others have to say...

On top of France. (and maybe Italy...)

On top of France. (and maybe Italy...)

Not sure. The drop-off on the Italian side of Blanc's summit ridge was a bit vertiginous and I was trying to get as close as possible without getting TOO close...

This is a GREAT ice ax.
I've had a few.
I think I'm all done trying out ice axes.
Probably...

The TrigRest is awesome and burlier than I thought it would be.
I got janky on a picket-bashing on the Breithorn and came down right on the plastic shank...thought I'd be reviewing the replacement TrigRest...but all it did was nick it up a bit.
The radius of the curve in the shaft is a good mix of harsh vs. mellow. You can climb AI2 and still self-arrest.
The spike thing on the end sort of fits onto/into the shaft a bit weirdly. There's about a millimeter of...off-kilter...ness.
It's sort of driving me crazy, but when my salt shaker is not in the EXACT proper location and orientation, it sort of drives me crazy.
I'm gonna file it off when I get around to filing the pick.

Speaking of pick, it's B rated. Shaft is T.
You can swap it out, but according to the Petzl cartoons in the Ice Ax Accessories PDF on their site, you can't swap it for, say, a Cascade Nomic U21100 T rated pick, but if you need a T rated pick you probably need a Petzl Nomic et al...

5 stars.

I just needed to weigh in and say that you get extra credit for having an Independent Trucks sticker on that puppy. Can't beat a little skateboarding love in the mountains.

HA! Amen, brother. Skateboarding is the good vibe through which all things rad in my life flow. It is the alpha and the omega...

Petzl Sum'Tec Adze...

Petzl Sum'Tec Adze...

The Sum'Tec Adze resting in camp at 10k feet on the SouthEast Ridge of Mount Tom near Bishop, CA in the Sierra Nevada.
Great ax.
Love at first swing.
I'm 5'6" and this is a 52cm. Might be the perfect size ratio for an all around do-it-all ice ax.
I bought the hammer as well, and one thing to note;
Both versions of this ax have a spike, not just the adze.
I'm not sure if my hammer version is old or new, but it has a spike, not a sawed-off bevel like the one in the photo on Backcountry.
If I remember, I'll come back and post a photo of them side-by-side.

The Sum'tec 52 has a spike; the picture is of the sum'tec 43, available only in a hammer (bevel design). I hope this clears things up.
