anyone with one of the first 200 NP sails with the sharp edging on the bottom, I can now confirm the potato peeler is the trick, after buying a new NP 6.2 Alpha, from this original stock, it took a massive 10 seconds per side to remove about .2mm off the sharp little edge and make it resisitant to scraping shins. That is, If you could be bothered to do it in the first place! Im sure there would be people that wouldnt even see this as an issue, but I trimmed mine just the same.
