Do you deburr your edges with a diamond stone at the end of every day? That is going to make 10 times more of a difference. That's the difference between doing stuff that actually matters... and doing stuff because you think that's what the hardcore riders do.
Not responding to me though surely? I'm certainly not 'good'. Though I'd hope you'd say I was decent for the 70 days I've had on snow.
For sure I don't do things because I think it makes me appear more hardcore. I'd need a time machine for that.
Some of us unfortunately spend more time reading about it than actually doing it and will never get to express our mega steeze by sessioning a handrail on a busted door with razor blades hammered in for edges.
Maybe the OP should have asked "is there any scenario in which sharp edges past the contact points on the tip and tail would be of benefit to me as a beginner?"
