Here's what our customers are saying

Andy Carroll 🇬🇧

"I wanted sharp knives, everyone kept telling me "just learn to use a whetstone!" But genuinely who has time for that lol. Bought this from an ad I saw online and couldn't be happier, I feel like I get the results that all these whetstone uers get and my sharpener does it in 5 minutes, no guessing angles and satisfying to use, 5 stars"

Olivia Rowell 🇺🇸

"My husband kept complaining the knives were blunt but wouldn’t do anything about it. I bought this on a whim (was hoping it would shut him up). Turns out he uses it every week now. He thinks he’s some kind of chef. Not sure it’s changed him, but the knives are definitely sharper and delivery time to New Mexico was quicker than expected"

Timothy Joseph 🇬🇧

"Took me a few tries to get the rolling motion right. I was pressing too hard like an idiot. Once I stopped treating it like a sanding block and let it roll naturally, it sharpened everything no problem. It’s not instant, but it’s better than paying someone to do it. And definitely less hassle than those rubbish pull-through ones and whetstones!"

John A Wills 🇬🇧

"I though the discs would ware out, but it's been almost 9 months now and they're still going strong, the diamondd are awesome, takes only a small amount of material off the blades and leaves my knives sharper than the day I got them. I would say there's a slight learning curve but only took me 20 mins to figure out."
