Just dress the curclips with some emery, wet’n’dry or a Dremmel so there is no sharp edge 😜
PS or just use the back edge of a pair of scissors and run that round the sharp edge, anything that is made of good hard metal...
I don’t think the edge even protrudes tho’ So it shouldn’t wear anything at all...
I cheated out and reused the same clips when I stripped, cleaned and rebuilt my box. No issues with it. I would replace them if I could find same quality parts. No fleabay cr@p!!
