I have been cutting the tape just a little longer than the blank and just trim the excess with a single edge razor.
Here's hopefully a better tip. I was having probelms cutting or using a punch for the holes for the split rings. A fine tipped soldering iron solved that.
Hint; After taping a bunch of spoons. Take a picture, the spoon that works the best will get lost and U will forget how U taped it. I always take pics of my spoons, (also lots of pics of Macs tackle box & spoons when hes not looking so I can copy his) TnT W-Fat
