19th February 2019 Reviewed by Martin Lithgow . For a die cast machine, it feels wobbly when pulling the sharpening mechanism forward,, it’s a minor niggle. It comes with a desk clamp, but is limited to what surface it can be fixed to as it fixes from the back only, it can only be mounted to the side or back of a desk, but it sharpens well.
