The M Power Credit Card diamond plate is a handy little sharpener, successfully used for years by woodworkers, crafters through to other groups such as fishermen and gardeners. The size is perfect however the Diamond Cross Credit Card has some great improvements, and it’s the first Credit Card diamond stone to incorporate a handle.
It sounds obvious but by not having a handle, the user has to hold the stone by the same surface that the tool is being sharpened on. So one slip and the first thing the tool tip or blade edge could meet is the hand that’s holding the stone. So it’s safer than before. And for those who like to use a lubricant when sharpening be it a lapping fluid or just water. The handle keeps the fluid on the cutting surface not on your hands, so there’s less mess.
