Provocraft's Cuttle bug is very handy for either embossing or die cutting. It works with a number of different dies including spellbinders, Quikutz and etc.
Punches are very tricky. A detailed image could look so good, but punching it typically requires supernatural dexterity. We choose punches that are easy to use and punch consistently time after time. We also try to get punches that do not break after fifty or so punches.
We carry guilliotine cutters and trimmers. Cutters can be used on a number of pages and do not warp over time. Trimmers are more compact. Their replacements and create different edges such as wavy, saw toothed, etc.
