A ceramic whetstone from Shapton in 1500 grit, great for kitchen knives, chisels, planes etc. Shapton's Professional range has long been admired for its efficient cutting, and is a firm favorite among woodworkers. Somewhere around #1000 and #2000 is the perfect grade for regular kitchen knife sharpening — in fact, a well known chef’s school in Tokyo gives one of these to each student as a leaving present. The plastic case doubles as a holding base, but alternatively you can use a towel. Splash with water before use, store dry, and don't drop.
