About this model

Sharpening jig using a whetstone. Baseplate has guiding rails, knife just gets inserted either in the 25° slot or laid on the 20° flat of the slider. Not even quite sure what to use the 25° for besides pocket knives that get heavily abused anyway. Could probably use an 18° guide even. Angles available: 20° and 25° Stone dimensions: 150x50x25mm Example stone, can be had cheaper - I got mine for $10
