Review: Elmasları maalesef döküldü yenisini değiştirmek istiyorum ama nasıl gönderecem bilmiyorum
Review: Jag är nöjd med denna slipsten, den är stor och ordentlig. Jag använder den till mina slöjdverktyg och köksknivar med bra resultat. Ska tillägga att detta var den andra stenen jag fick för den första var defekt med "blåsor" i ytskiktet så det trillade av när jag använde den. Men denna är som den ska.
