Our standard Coarse wetstone - always gets the blade sharp.
This is the coarse wetstone used by the workforce at Slåttergubben. It feels good to work with wetstone with Swedish origin.
If you choose to buy just one grindstone, it should be this one or the medium wetstone. Using a coarse stone results in more frequent peening. Never compromise with thw sharpnes though. If it is sharp, it is fun. If it is fun the mowing tends to be done.
Do not use this stone to repair damages on the blade, it is to soft. Use this one instead or something else that is hard.
