Super easy

nestly expected sharpening to be a hassle. this took maybe a minute and my knife feels so much better.

Love the design

looks beautiful on my counter and actually works. feels like a proper tool, not another cheap kitchen gadget. 😍

This is incredible

i could never keep the right angle with my old sharpener. the guide makes it much easier.

My knives needed this!

One of my knives was basically useless. sharpened it with Katusharp and it’s back in rotation!!.

great for beginners

i’ve never been good at sharpening knives. this is basically impossible to mess up.

Want a Simpler Way to Sharpen?

Beginner-Friendly Sharpening

Katusharp™ guided 15°/20° angle keeps the sharpener aligned with the blade as you roll. No freehand angle control or sharpening experience needed.

Sharpen Without Water

Our industrial diamond disc works dry, so there’s no soaking, water tank, or messy setup. Roll it over your knife and get straight back to cooking.

Sharpness That Lasts

Oak, aluminum alloy, industrial diamond, and N45 magnets make our sharpener durable enough for years of repeated use.

Japanese Craftsmanship in Every Detail

Industrial Diamond Abrasive: A 400# diamond surface restores dull edges with control.
Fine Honing: The 1000# side gently refines the restored edge for a smoother, cleaner finish.
Guided 15° / 20° Angles: Precise angle guidance helps create a consistent edge.
Premium materials: Oak & aluminum alloy come together in a refined design made for everyday knife care.
Magnetic Base: Strong N45 magnets help keep the sharpening system securely aligned during use.

Sharpening is actually enjoyable now

I used to put off sharpening my knives because it felt like a whole thing 😀 With Katusharp, I just grab it, roll a few times, and I’m done. My everyday chef’s knife feels noticeably better.

Sturdy excellent materials

Tbh I bought it partly because it looked good. The oak is gorgeous and it feels really solid in your hand. Then I actually used it and realised it’s probably the easiest sharpener Ivve owned.

Perf for bbq knives

This brought one of my old blades back surprisingly quickly. Now I keep the sharpener right there with the rest of my BBQ gear.

Very satisfying tool

Theres something weirdly satisfying about using this. You can actually feel the difference as you roll it along the blade. I’ve ended up sharpening knives that weren’t even particularly dull just because it’s so easy 👍

Much nicer than cheap sharpeners - great value

My old sharpener was one of those cheap plastic ones that lived in a drawer and made me nervous every time I used it. Katus feels like a proper tool. Heavy, well made, and actually enjoyable to use.
