Lihv

Lihv is a term of Estonian origin that refers to a grinding or sharpening stone. It is typically used for the manual maintenance of tools, particularly knives and axes, to restore their cutting edge. Lihv stones are often made from natural materials such as sandstone or slate, though modern synthetic abrasives are also used. The process of lihv involves rubbing the blade against the stone in a controlled motion to remove small amounts of metal and create a fine edge. The grit of the stone determines the coarseness of the sharpening; coarser grits are used for initial shaping and repair, while finer grits are used for honing and polishing. Proper lihv technique is essential to avoid damaging the tool's blade and to achieve a sharp, durable edge. In a broader sense, "lihv" can also refer to the act of sharpening itself.
