With the self-sticking stamps we now have perforations and die cuts such as 9.5 and 8,25. I have two perforation gauges, Uni-safe and Stanley Gibbons Instanta. The former provides measuring down to 7 but only does it in 1/2 steps. The latter makes it possible to measure in much smaller increments....perfect, except that it only goes down to 10. Nothing smaller can be measured. Is there a gauge that does both? How does the rest of the philatelic world do it? All suggestions will be appreciated !
