Ooh, RM22.95 for a 4-in-1 sharpener is pretty decent lah, especially if you're the type yang malas nak spend time with a stone haha! A few of my mum friends have those quick sharpeners and they say it's handy when you're rushing to prep dinner, though honestly some of them still prefer the stone for their good knives, depends on la if you're using budget knives or the fancier ones, because the quick ones can be a bit rough on expensive blades. But for everyday kitchen work in a busy household? Worth trying at that price, especially with the shocking sale tonight!
