2 in 1 Sharpening Stone, Double-Sided Sharpening Stone for Garden Tools Kitchen Knives Scissors Axes (Grit 150 280)

Nonostante sulla scatola sia riportata la grana ordinata, 400/800, all' interno c'è una pietra grana 180/320... Pietra inutilizzabile per i miei scopi.

I actually bought three of these circular stones, each with different combinations of grits, so that I have from 300 to 1000 grit. The grits are all a little finer than I expected, but this is not a problem. The 300 grits brought a very poor and damaged edge (on an old 360mm/14inch cleaver) back into good enough condition to sharpen properly. The stones with the higher grade grits are quite soft (not at all like like natural stones such as Arkansas, Coticule, or Nakayama) but once you realise this it is not a problem and at these prices these carborundum stones are excellent value. I have sharpened the old cleaver, a very cheap machete, and a reasonable quality hatchet. I was easily able to put very good edges on all three, each quite sharp and fine enough to cleanly slice paper. Make sure you soak them in water and keep them wet during use. Treat them gently and they will give you very good edges with minimal effort.

Ich benutze den Schleifstein für Werkzeuge. Durch die zwei unterschiedlichen Körnungen lässt sich eine Axt z. B. sehr scharf schleifen. Für Messer würde ich zu hochwertigeren Schleifsystemen greifen.

Arrivata come sempre puntuale, la pietra si presenta solida, le 2 parti abrasive si differenziano alla perfezione con i 2 colori differenti, le grane mi sembrano ottime, non ancora usata, mi riserbo il futuro se modificare il giudizio nel caso siano scadenti

Non avevo mai usato una pietra per affilare, quindi sono poco esperta, ma la forma è molto comoda per fare pressione con il coltello. Occhio a dove la usate perché essendo ruvida da entrambi le parti potreste finire per rovinare il piano della cucina, io l'ho appoggiata al tagliere e usata facilmente
