In reply to SDee:
I used these in the past, they were strong on design, if not over designed and weak on materials/build quality.
Watch for wobbly heads, the heads were held in with resin and then rivetted, over time the resin would crack and fall out leaving a wobbly head.
The thin rubber grips shredded easily, replace with SA tape.
The soft alloy head got mashed up easily making pick changes difficult.
They are a straight axes, this has its advantages but you WILL wreck your knuckles, they will need wrist loops or very strong forearms to uses leashless.
Finally the big hole in the spike acts as a crampon magnet and does it's best to trip you up when de balling your feet.
I wouldn't buy without careful inspection IE not online.
They will be good enough for your required use, some of the hardest routes of their era were climbed using them but would have to be very, very cheap to tempt me.
