Buyers' Guide - Ice Axes | | Buyers guides in association with |  |
|  | It's winter, which means one thing, or ought to - SNOW! If you're
going to be heading out into the mountains in proper winter
conditions then you need an ice axe, crampons and the skills to use
them effectively.
We'll cover crampons in next month's Buyer's Guide, but this month
it's the spikey things that you hold in your hands we're looking at -
what type of axe, how long, leashes and more. Choosing the right ice
axe can make a big difference to your winter walking or
mountaineering and could, in an emergency, be the difference between
life and death...
What
Are They For?
If you're a walker or general mountaineer, your axe has two main
functions. One is to improve stability on steep, snowy ground
by providing a secure support or anchor as you move. The second is to
be used as a brake in the event of a slip. 'Self- arrest' as
it's known, is a skill that you need to learn from either an
experienced friend or, ideally, from a professional winter skills
course run by a qualified instructor. Even if you're experienced,
don't take your skills for granted, you need to practice, so that
whichever way you fall, using your ice axe is instinctive.
Another use, though it's less common that it was, is to use the axe to cut steps across isolated patches of ice and save the palaver of donning crampons.
Climbers on steeper ground also use their axes as surrogate hands
above their heads, both to hold them in balance and, sometimes, to
pull up on. Because the demands of climbing are different, high-end
technical climbing axes aren't always ideal for general mountain use
and specialist walking axes aren't as secure on steep technical
ground as a proper technical axe.

Brands
Even walking axes tend to me made by specialist alpine hardware
brands, so you may come across some brands you're not familiar with.
Don't panic though, there are plenty of decent axes out there and the
introduction of EC safety standards means that they all conform to
minimum levels of strength.
Brands we'd look out for include Black Diamond, DMM, Mountain
Technology, Petzl Charlet, Simond, Grivel, also HB for technical
axes. All have a good background in making winter hardware and can be
relied on. Check out our user reviews section for some user
feedback.

Types of Axes
Walking
Axes are characterised by the near horizontal angle
of their pick. Originally all axes were designed this way and the
shallow angle of the pick makes them ideal for use during self-arrest
or ice-axe braking. By the same token, the flat pick won't grip well
on steep ground swung above the head climbing style, so choose one of
these only if you're sure you'll be on mainly straightforward,
non-technical ground and nothing steep or scrambly.
Mountaineering Axes -right -
are halfway between walking axes and full-blown technical climbing
tools. The pick tends to be stronger than with a straightforward
walking axe and is curved downwards in a more pronounced way. The
droop on a mountaineering axe will mean it holds much better in
climbing situations, but will still dig in smoothly without grabbing
when self-arresting. Axes like the DMM Cirque or Raptor, Mountain
Technology's Technical and Mountaineering Axes ans similar will allow
you to climb moderate winter and alpine routes and still work well
for more general use.
Specialist Technical Axes look
butch and tough in the pub, but are very specialised tools designed
to work on steep ice climbs. Typically they'll have a curved or bent
shaft to protect the climber's fingers from bruising, a very
supportive leash and a reverse curve or banana pick to give maximum
purchase on steep ice. You can ice axe brake with a reverse-curve
pick, but it's much harder than with a straighter walking axe since
the shape tends to catch suddenly rather than engage smoothly with
the snow. For general use they're not worth considering, so only look
at these if you're climbing hard, steep technical routes.

How Long?
There's
a lot of debate over how long you need an axe to be. Some
mountaineers prefer an axe long enough to act as a walking stick on
flat ground, however, we - and Glenmore Lodge - suggest that for
general mountaineering, a shorter axe is best.
Why? First, on steep ground, you plunge the shaft of the axe above
you for protection. If your axe is too long it'll be level with your
shoulder rather than your hip where you want it to be. Next, during
self arrest, the spike of a shorter axe is less likely to stick out
from your body and catch if you fall.
Generally an axe that's down to your ankle when held in a straight
arm at your side is about right for most people. A good shop will
advice you, but in general, if you want an axe to use as a walking
stick, then you may be better off with a walking stick... Short
enough for steep ground, but long enough for balance on ridges
without having to crouch too low is about right.
Climbing axes are matter of preference, but most are now around
45-50cm in length. General axes go up to around 60cm or so and for
walking axes, the sky seems to be the limit.

Leashes or Not?
Climbers
use leashes - effectively a loop of nylong attached to the axe - for
support when hanging from the axe on steep ground. For walkers
though, it's a more complicated matter. When zig-zagging up slopes,
you need to change hands on the axe whenever you change direction and
taking one hand out of the loop and inserting the other is fiddly and
slow.
Many skills courses teach that your shouldn't use the leash in
those circumstances, however that does mean if you drop the axe, it's
off on a toboggan ride to freedom... The neatest answer we've seen is
the Grivel spring leash that attaches the axe to your body allowing
you to change hands on the axe head without risking dropping the axe.
It's a great idea, especially if you're prone to dropping things...
|
Comfort
For
walking and general use, it's important that the head of the axe
feels comfortable in your hand and is secure even when wearing gloves
or mitts. Some axes, like Grivel's Eagle or Black Diamond's Pro Raven
have been designed with shaped heads to make this easier.
For climbing and mountaineering use, make sure the shaft of the
axe sits comfortably in your hand as well. Non-slip rubber handles
will help, but those with small hands may need to choose carefully
for maximum effectiveness and to stop the axe twisting in their
hands.

Weight And Strength
Virtually all axes these days use alloy shafts and steel heads for
a combination of lightness and strength. There are two EC ratings -
'B' which is 'basic' and mostly applied to walking axes and 'T' for
'technical' for climbing axes. The standard is mostly about the
strength of the shaft and whether it's suitable for use as a snow
anchor. As a walker, a 'B' graded axe will be fine.
There are also a number of ultra-lightweight axes designed for ski
touring and high altitude use which have alloy heads to save weight.
These are fine for general walking use, but the alloy head isn't
designed to take big loads on steep technical ground, so for general
mountaineering use, suffer the extra grammes and go for a
steel-headed mountaineering axe.

Care
Axes
are pretty tough, but always dry them after use and store in a dry
place. Keep the pick reasonably sharp and to the original
instructions and protect the tool and other people from damage with a
set of rubber spike and head protectors.

Other Stuff
It's temptring to go lolloping around the hills with a
butch-looking technical axe, but unless you're actually going
climbing, you'll be be better off with either a straight walking axe,
or one of the many intermediate mountaineering axes.
When buying, be wary of shop assistants, some of whom have quaint
ideas about how long an axe should be. If you want a walking stick,
buy a walking stick.
