Oh trust me, if I had the time and money these would be made, tested, and tweaked so we could drastically reduce edge pullouts:
That thread gives you a good look at why it's not happening. Edge manufacturers are mostly the root cause of the issue. What they have works well enough for most of skiing's needs; and for them to invest in new shit that might not work, that doesn't translate to $$$ in their pockets.
Ski manufacturers might not like really good edges either. Sounds stupid but if I knew people were going to be buying skis every year because that's the rate my product deteriorates at, then I won't touch the product. Seems like an odd theory but I feel like it's a contributing factor. Personally I feel like it's a great selling point but who knows...
Then people are skeptical which is the lamest shit of life. "Reality is a bitch". No one has fucking tried it, so reality hasn't even happened. Theory is maybe a bitch, but until we try that or something like it, we don't know if reality is a bitch or not. This relates back to manufacturers not wanting to try something like it. R&D isn't cheap in the short term but if a drastic improvement comes along then I think it would be worth it in the long run.
Who knows, maybe some open minded thinker who has the capability of developing edges at a reasonable cost will come along, improve upon the current standard or my idea (and other poster's ideas in that thread, there were some good ones). Hopefully one day, we will see a better ski edge
