I lost my 3 year old FFG Delica 4 on a recent hike (right after losing my mini gripnot having a good month!), and I ordered a replacement that arrived today. My previous Delica had an incredibly smooth opening action, but the new one is much harder to open. If I open it with my thumb and forefinger it is rough and jerky, but if I use my thumb on the hole I can actually hear a grinding noise. I also noticed the hole itself is very poorly finished. Is this acceptable these days, or should I ask for a replacement? I am pretty bummed because my last Delica was perfect
