My name is James Carter. A few years ago, I watched my mother struggle with a blunt kitchen knife.

She pressed harder, the knife slipped, and she cut her hand. It wasn't serious — but it stayed with me. She had used the same knives for thirty years. She didn't need new ones. She needed sharp ones.

I searched for a sharpener that was safe, simple, and actually worked. Everything I found was either a cheap pull-through that ruined blades, or an expensive whetstone that required a skill most people don't have.

Then I discovered the rolling sharpener — a diamond wheel, a magnetic angle guide, no skill needed. Sharp in 60 seconds. The only good version cost £139. For most families, that's simply too much.

So I built Karvé — the same technology, the same results, at a price that makes sense.

Today, thousands of UK households use Karvé every day. And my mother hasn't had a blunt knife since.
