these stones come glued to wood boards. every single stone of mine snapped off the wood after the first use. and the #5000 grit stone actually broke in half while using it. the stones feel nice but I haven't been able to get any response from support and the broken stone doesn't bode well for the other 4.
These stones were a seemingly random assortment of countertop remnents and other stuff. The surfaces had obvious saw marks and there was no way to determine what grit any of them corresponded to. A complete waste of money
I absolutely love these. Every grit came out nicely and was not poorly made. Managed to get all my kitchen knives sharp enough to shave my arms.
I like the 5 piece set better than the original 4 piece set that come with the sharpener. The original 4 i have a hard time keeping them in the handle. the second time i used it my 600 grit fell out and broke. The 5 piece set has a nylon backing that hold alot better. Over all i like it.
My husband loves this sharpener! Glad we got it
