I've never cut a flake. I enjoy rubbing them out -- to varying degrees -- or just folding them and rubbing out the ends so I can light them easily.
For me, handling flakes is just fun, not intimidating. It adds a tactile dimension that you don't get when simply filling a pipe with a ribbon cut. Yes, it does require some effort, but so does pipe smoking in general. That's part of the charm, I think.
Zonomo, I think you'll find that there's no one way to handle flakes. Each flake may require its own approach. Penzance is a velvety soft flake that I just love rubbing between my palms; it breaks up very easily and, in fact, will break apart on its own if you leave it in a jar for a month or so. Stonehaven is almost paper-thin and rubs out very easily. Other flakes require more effort. And Dark Star requires patience, effort, and maybe even the shedding of a few tears before you can break it down enough to put in a bowl. (That's one that I definitely will try cutting up the next time I pop a tin.) But the reward is worth the effort: if you enjoy stoved Virginias, Dark Star is the pinnacle, IMO.
