What people say once they feel the difference in every cut

★★★★★

“I thought squashed tomatoes were just normal, until I tried this”

I'd been cutting like that for years and blamed the knife, not the edge. Two minutes on SLIPA and it was sharp again. Now I slice without forcing it, every day.

“I didn't know there was a cheaper alternative to the big-name rolling sharpeners”

I'd been eyeing the expensive imported ones for ages. This does the same job for a fraction of the price, and I honestly don't feel I'm missing anything.

“Gave it to my mum and now she brings it up at every family dinner”

I wanted a gift that was a bit different and got it right without knowing. She uses it every Sunday and has already asked for one for my sister.

SLIPA PRO taken apart: roller body, axle and disc
Coarse 400 grit diamond disc

Diamond disc 400 for fast sharpening

The 400-grit diamond disc is built for quick, efficient sharpening. It brings worn, dull knives back to life with ease and bites even into hard steels. Tough diamond grit gives you an even, precise result from the very first pass.

Fine 1000 grit diamond disc

Diamond disc 1000 for a precise finish

After the first pass, the 1000-grit disc refines the edge and makes it smoother. It gives you a cleaner, more controlled cut and a higher-quality finish, every time you use it.

Bonded diamonds for maximum efficiency

The bonded diamonds in our discs give more cutting power, so you sharpen faster from day one. They are hard-wearing too, which means a consistent, precise edge with every stroke and less time at the worktop.

The 20 degree side of the SLIPA angle block

20° angle for a lasting edge

The 20° side gives you a strong, durable edge, ideal for sturdy European kitchen knives and everyday cooking. It also gives stable, reliable cutting on hunting and outdoor knives.

The 15 degree side of the SLIPA angle block

15° angle for exceptional sharpness

At 15°, even the finest knives, like Damascus or high-carbon steel, reach an exceptional sharpness. Their hard steel takes a finer, more precise edge.

Chef's knife held by the magnetic angle block

A secure hold with maximum grip

Made for superior grip, the SLIPA™ PRO holder keeps the blade firmly in place the whole way through. Together with its strong magnets, it holds even small knives securely, giving you full control and stability every time.

Underside of the hardwood block with non-slip feet

Made with precision from quality materials

Selected wood, dried for weeks, precisely machined and checked by hand, becomes a product with real quality and detail. The natural grain gives every SLIPA™ PRO its own character and an elegant finish.

SLIPA PRO

Questions? Answers.

Everything you need to know before and after your order.

Do I need any experience to use it?

No. SLIPA PRO is designed so that sharpening is very hard to get wrong. The block holds the correct angle for you, the magnets keep the knife in place and the discs do the work. All you do is roll. In about 3 minutes, with no prior knowledge, you get a professional edge.

Does it work with any knife?

It suits the vast majority of kitchen knives: chef's, santoku, paring, filleting and utility knives. The 15° and 20° sides cover Japanese and European knives. It is not suitable for serrated knives, ceramic knives or single-bevel blades.

Can I damage my knife if I use it wrong?

Not if you use the right angle for your knife (15° for Japanese, 20° for European) and don't press hard. The weight of the roller is enough. Repeatedly using the wrong angle can change the edge over time.

What's the difference between 15° and 20°?

15° is for Japanese knives: harder steel with a thinner, more precise edge. 20° is for European knives: tougher and more versatile. If you're unsure, use 20°, it's the safest choice and fits most knives on the market.

How long do the diamond discs last?

They are made for hundreds of sharpenings with normal home use. It's time to replace them when the coarse disc no longer brings back a very dull knife, or the fine disc leaves a rougher finish than usual.

How long does it take to sharpen a knife?

3 to 5 minutes for a knife in normal use. If a knife hasn't been sharpened in a long time you'll need more passes with the coarse disc before switching to the fine one, which can take 8 to 10 minutes. With regular upkeep, 3 minutes is enough.

How often should I sharpen my knives?

It depends on use. If you cook every day, every 2 to 3 weeks. If you use your knives a few times a week, once a month is plenty. The easiest test: rest the knife on a ripe tomato without pressing. If it sinks in under its own weight, the edge is fine. If it squashes the tomato, it's time to sharpen.

Can I sharpen Japanese knives with SLIPA PRO?

Yes. The block has a 15° side, the standard angle for Japanese knives. Always use the 15° side with them, as sharpening them at 20° can wear down their characteristic edge over time.
