The Apex and Switch – DMM Ice Tool Review

DMM is not well known in the US. When you think of ice tools, you think Petzl, Black Diamond , Grivel and most recently Cassin, not DMM. Well once you have a look at these tools, you will start thinking about DMM.

In mid February, DMM gave NEice some of their newest ice tools to review. Since then we have tested them at Lake Willoughby, Cannon Cliff, Crawford Notch and Frankenstein cliff. We have climbed ice from 3+ to 5+ in temperatures ranging from  -5  to 45 degrees F. In all, we logged over 100 hours of climbing with these tools and they are fantastic!

The first thing you will notice about the tools is the quality. The manufacturing of these tools is some of the best I have seen. DMM has been around since 1981 and it shows in the construction and design of these fine tools.

Switch: In my 35 years of ice climbing, the Switch is the best ice tool I have ever used!  – Doug Millen

The Apex ($239)

I was lucky enough to demo pair of DMM Apex tools (thanks NEice.com). From the first time I held them I could tell that they were my next gear purchase. I’m not going to spend time on specifications, that’s what Google is for, I’m not technical enough to know why they matter. What I do know is these tools are perfect for the climbing I do and affordable enough that I’ll have new tools and enough left over to pay the tolls between me and the ice.

The first climb on the DMMs was a moderately steep pitch of 4 ice. A few swings of the Apex and I felt like they had been mine for years. The grip fit my hand well and the tool felt balanced, a little less top heavy than the Cobra. Although the shaft is straighter clearance between my hand and the ice was more than enough. The Apex felt more like the Petzl Quark then the Cobra having a different pull which you could feel in the angel of the wrist.

Bottom line… If you’ve been climbing on Vipers, Cobras. Quarks. etc. and dreaming about a more technical tool that climbs and canes even better, the DMM Apex is your next set of tools. When you consider price and performance of this tool there is no better for the majority of mere human climbers.

 The Switch ($279)

I have used Nomics for years and I was curious about these tools.

They are slightly heavier than the Nomic but the extra weight feels good and requires less swings in hard ice. The Pick weights are included but I found I did not need them. At about 1 inch longer than the Nomic it was easier to reach for better holds. The tool is fully T rated and you will not be able to break any part of this sturdy tool. The hand grips of the Nomic feel fragile and weak in comparison to the Switch. The handle is glove friendly, hot forged ergonomic with full strength upper and lower rests. If you use different gloves in different conditions you will like this grip and big hands fit well. The coating on the handle is great, I never felt like I was slipping out, even on overhanging ice. The swing of the tool is perfect too and so natural. I am a carpenter and I know a good swinging tool when I feel it. The picks come with the perfect shape for ice or mixed climbing and are pre-tuned. I never touched the picks with a file.  The Picks go right in, and come right out, no problem,  yet they feel really sticky and secure in the ice. The Switch as it’s name implies remains in balance when switching hands on the rests.

The only concern of mine is how the coating on the handle will hold up over time. So far, so good, not even a nick.

Bottom Line…I have switched from Nomics to the Switch, and I have loved every moment of the last 6 weeks climbing with this tool. The Switch is now my tool of choice.

DMM Testing: SLINGS AT ANCHORS

SLINGS AT ANCHORS

October 4, 2013

A great video and report on the forces at work on slings in four different belay set-ups.

In a previous video we compared the impact forces generated using nylon and Dyneema® slings with a dynamic load. It clearly highlighted the importance of ensuring there is no slack in a system using slings. As an example, a 85 kg mass free-falling just 60 cm on to a 60 cm Dyneema sling (fall-factor 1), with an overhand knot in it, generated enough force to break the sling.

Extending this previous theme we’ve looked at using nylon and Dyneema® slings in four different belay set-ups
