I picked up a Trend Diamond Whetsone yesterday, the DWS/P3 model, it's designed for sharpening router bits and measures 75mmx25mmx0.7mm. Will fit nicely onto a hard sheath with a bit of harry black. No use for hard sharpening jobs, but does the job for a quick "brightening" after a work session in the sticks.
