I found it to be useless..., first, it was not comfortable to handle, probably a combination of it being too small and/or my arthritic hands made it clumsy to handle. That, alone, would not have mattered to me as long as it did what it was supposed to do [my reason for purchasing it]—Sharpen! That, it did NOT do. Fortunately I have my long-time friend next door who takes all my "online rejects...," that way I don't feel guilty for wasting money or for being too lazy to return it [it also gives me a good reason to buy a different one]. I did buy a different one after doing more research so when/if I can finally figure out how to use it, I'll be back with a more positive review.. Paula Angel. Des Plaines, IL. Mon Jan 09 2017
