I saved my dull knives with a $20 sharpener style favored by Bobby Berk – it's easily my favorite kitchen buy of the year

I’ve had my kitchen knives since 2012 but recently, they wouldn’t even cut into tomatoes. I started looking online for a new set, until I remembered Bobby Berk using a magnetic rolling knife sharpener.

With many on sale for Black Friday, I decided to give one a go as a it would be at least 50 per cent cheaper to sharpen, rather than replace my knives.
