Charlotte Chan  asked the Naked Scientists:
   
Hi!

I really like newbielink:http://www.thenakedscientists.com/HTML/podcasts/ [nonactive]! Thank you so much for sharing all  this amazing knowledge.

So my question is:

Why can skating blades support the weight of a human and what type of metal is  the blade made out of so that it's long lasting and resistant to rusting and so forth?

Thanks!

What do you think?

Hmm :)

Rust free steel seems to be the common choice for skates today.
Same as in your kitchen knife I would guess?

Before that they were made of all kind of materials I think, primary bone. The Eskimos have a trick where they 'coat' the edge of their sledges with fast freezing water/snow making a very hale layer on which the sledge glide.

Maybe there are new ceramic materials, or possibly plastic that would do as well?

Ice Skates.
