This is a double “V” ceramic sharpener. It’s essentially a mini set of crock sticks with medium and fine grits available on either side of the sharpener. It is constructed of ABS plastic and has slip-resistant grip pads and base pads so that you can set it firmly on the table should you choose to do so. It has a key ring hole. It’s definitely compact and would fit in a pocket or toolbox quite well. Quick and easy to use and would be handy to have nearby to touch up your blades for routine maintenance or when doing especially rough chores like cutting up cardboard or old carpet.
