A man has to learn to cut off either shoulder. He must also be able to cut steps with either hand alone, in order to have his other hand free to take handholds on the exceptionally difficult passages or traverses where these are found necessary. To aim a step with one hand needs practice. To keep a firm grip on the axe shaft, more especially as this gets iced, makes it important to secure a shaft that is well balanced and easily grasped. It may well have some protuberance or collar which prevents the hand slipping. For the same reason the sling is a sound precaution.[14]
To cut handholds in ice calls for a very fine touch. The best that can be usually formed is no more than a steadying nick, over the edge of which the glove can be hooked. The hand shapes the edge of the nick to the curve of the fingers by pressure, and in the process the glove freezes slightly to the ice. The hand can rarely give more than a balance hold on ice. Security and anchorage must be given by the feet.
Similarly, the hand or rather axe hold that we make by driving in the pick above us, in order to help us over a bad step, is usually inadequate. The pull that comes on the shaft with our weight must always be from a direction different to that in which we drove in the point, and the strain will either loosen the point or lever out the section of ice which the blow has in part detached. To drive in the pick straight and not on a swinging arc, so that it may remain firm at an angle to take the pull of our weight in transference, requires a kind of arm stroke very difficult to make with sufficient force in hard, steep ice.
For men without claws the scrambling method, which some leaders risk to save labour in cutting, of alternating one good ice step with a scratch for the other foot, covered by an axe hold, can only be excused by rare circumstance. It is far better to take the little extra time required for making sound steps under both feet. Men on claws, however, are better able to use handholds and pick holds in ice. Their feet are firm so long as the angle and their nerve allow them to stand upright in balance. All they require is a balance hold, to cover them in starting the next movement; for so much assistance a hand nick or a driven pick can well be trusted.
The step for the foot which is passing inside and next to the ice slope can, to save time, be made smaller than that for the outside foot. For a good party, without claws, the step for the inside foot need only be a nick for the side of the boot, provided always that it is inclined at the right angle. To use such steps it is obviously important that the whole party should follow with the same foot. For men with claws there is no need to make this differentiation. Wherever steps are needed for claws, they may all be made of the same small size—just a sufficient nick to take the side points of either claw.
In cutting on a diagonal uphill, for men without claws, it is better to make the interval between the steps shorter when the rising step is to be made from the inside foot on to the outside foot. In rising from the outside foot on to the inside foot a longer stride can be made in balance, and the interval between steps can be made longer.
In cutting diagonally on the downgrade, the contrary is the case. In dropping from the inside foot on to the outside foot a longer stretch can comfortably be made than from the outside foot on to the inside foot.
In cutting horizontally, a longer stretch can be made from the outside foot on to a step for the inside foot, than vice versa. Trifling distinctions; but a good cutter who remembers them will save the inches on his alternate steps; and many inches saved on long ice slopes mean a number of steps spared and minutes, even hours, economized.
For men without claws, or not very expert, it is better to make steps too near together than too far apart. Safe progress is the best progress. This applies especially to cutting downhill. Until a climber is thoroughly practised in lowering his weight on the bending of a single knee, he will always find one instant of delicate balance in a descending stride; and the longer the interval between steps, the more difficult the balance, until the point comes at which he is reduced to axe scraping, or shuffling himself down the ice leaning against his hand. When he finds either help necessary, the step cutter should be given warning at once that the intervals are too long.
Cutting on the downgrade is usually found more difficult than cutting uphill. At the same time, the securing of the right fashion and inclination of the step is even more important on the downgrade than on the up, since the balance in taking a down-step is more difficult, not only for the cutter but for his following. The steeper the angle at which steps have to be made downhill, the more awkward becomes the balance; until, in descending at a very steep angle, the cutting has practically to be done with one hand. For this reason, on very steep slopes it is better to cut short descending zigzags of an easier angle, even in narrow couloirs where economy of time and labour would point to a vertical ladder.
