Ugh, should have just listened to you, day one! It's been over 2 weeks now still impossibly hard to open after, DAILY wear. coarse side of emry board helped alleviate the tightness a little bit, however the polishing side...I've seen a few people mention this. You could emry the points of contact, at the point where friction holds it together, just a little bit to take the sharpness off the edge, it'll give a smoother action. Just don't over do it!
I used the smooth polishing side of the board on sharp edges of the bracelet and clasp... and wow. I made sure not to over do it, but when I closed my eyes and touched the stropped side vs stock side, it was night and day. No more razor sharp edges, everything feels like it was finished by hand.
