And to answer the original question, no matter what im pretty sure edges would crack. And if they were strong enough not to, theyd be too rigid and the ski wouldnt flex right and it would probably ruin the rest of the ski really fast.
oh dear god, gold? why would you even consider that. Edge's are made of steel, and gold is too dense and maluable, it woulnd not make goot edge material. No matter what they use of the materials we have now that are cost effective steel is the best choice. No matter what they will eventually crack , think about the amount of pressure you put on them
its like buying a ferrari and shitting in it- happywhenhard
