Simond Racing ice screws
Simond Racing ice screws are without peer. Although most manufacturers are producing high-quality ice screws these days, there are several attributes that set Simond Racing ice screws apart.
Let's look first at machining, because the quality of the machining determines how easily an ice screw can be wound into ice, and hence how much time and energy you have to spend in placing the screw while hanging one-handed from your axe. (1) Simond Racing ice screws are tapered
to reduce friction as you turn the screw into the ice (i.e., the mouth of the screw is slightly wider than the base, although this won't be visible to the naked eye. There are only a couple of other products that incorporate this important design. (2) Simond Racing screws are nickel-plated to reduce friction, demonstrating Simond's expertise in materials design. (3) Simond Racing screws are produced in the Simond factory in Chamonix, allowing the strictest quality control and testing, rather than being outsourced for manufacture in China with inferior metals (anyone else noticed all the recalls issued for climbing gear manufactured in China recently?). (4) The winder of Simond Racing screws does not need to be folded in and out and is larger than that of the Black Diamond Express screw, and hence easier to use when wearing a glove.
A few other points.
There are two clip points on the hanger.
At anchors, this allows the second climber to clip a daisy chain
directly onto the screw rather than onto his/her partner’s carabiner.
It is even more useful for leading, since after you place a screw as a runner, you can clip a daisy chain to the screw and
rest, then clip the quickdraw and rope at leisure.
You may be wondering whether to choose an ice screw with a long flip-out winder (as on the Simond Tornado ice screw (discontinued) or the Grivel series) or a stubby winder (as on the Simond Racing ice screw or the Black Diamond Express ice screw). Wisdom was that the long winders produced more torque for winding but made racking ice screws on your harness more cumbersome. To be honest, a modern-day ice screw shouldn't need the extra torque of a long winder; if it does, there are probably issues with the ice screw machining. Long winders were probably only introduced to achieve a point of difference from models having stubby winders (i.e., they were solutions to problems that didn't exist). Don't even think about getting an ice screw that requires you to carry an additional device to screw it in (yes, that is a design still available...) and you will probably regret not spending the extra few bucks buying screws without winders (and hence we don't stock them).
There's a bunch of other design considerations that are a bit too technical to go into here, mostly relating to how the teeth have large taper and bevelling, the former making it easier to get the screw to bite in the first half-turn (important when placing screws one-handed) and the latter adding to the ease of placement in general.
The handles of the Simond Racing screws are colour coded to quickly identify the length of
screw on your harness. Lengths are 13, 17, 21cm. The 13cm screws are used more for mixed climbing on thin ice, the 17cm screws for water ice and hard alpine ice, and the 21cm screws for hard and soft alpine ice.
