Large natural Slovakian whetstone with very fine grain, the Rozsutec

+/- 25.5*3.9*1.6cm

For honing peened scythe blades. This high-quality stone is particularly appreciated by experienced mowers who are proficient in peening and honing. 

 Natural whetstones are carried on the belt in a water-filled whetstone holder for frequent maintenance of the edge during mowing. Adding a small dash of vinegar, as was done in the past in certain regions, increases the bite of most natural whetstones and helps keep them clean and functional.  If you use the Rozsutec with just water, it tends to glaze over time, but adding a little vinegar avoids this problem.
