i lost Nan’s sharpener that worked really well. since it was a round thing about an inch and a half in diameter, i guess i must’ve thrown it out with the trash anyway, i bought a wusthoff sharpener that kinda looks like that one you have but it’s very temperamental – u kinda have to get ur knife at the right angle to sharpen it – if not, i think it dulls the blade instead!

i will look for a farberware sharpener like urs.
