Sol.inge

Multi-Blade Sharpener

Stay Sharp

Most of us don’t sharpen our kitchen knives, tools, or other household blades correctly—if at all. Sol.inge’s blade sharpener is a single, multi-purpose tool that lets you keep many different blades in top form.

To properly sharpen, you need the right angle for the blade. Normally that would mean a special sharpener for every
single tool. But Sol.inge’s tool has two sets of self-adjusting plates. They move to create the proper angle for sharpening each blade. Work on a variety of tools, from scissors to knives—even those with serrated blades.

A stationary blade lets you tackle heftier jobs like garden shears. And for smaller surfaces like cheese graters, nail clippers, and can openers, there’s a pop-out handle with a blade to get them in shape.

Creator Marc Adam has been perfecting this sharpener for years, combining his efforts with knife makers and engineers. He made this tool so versatile that it will put an end to dull, annoyingly ineffective blades.

    The five plates of tungsten carbide, the sharpening material, have the highest roughness possible, about 93HRA. Each carbide plate has 4 edges.

    It will take you years to wear them off, but when it happens, just use another edge of the carbide plate. They are inter-changeable!

    We guarantee the carbide plates 10 years.

    Please also note that they don't rust.

    Would this work on blades of a push lawnmower; the kind with a reel style blade? Because they are curved, they are tough to sharpen with other blade sharpeners.

    I would need to quickly take a look at the blade you are talking about. But as long as it is made of metal, the MultiSharpener can sharpen it.

    The MultiSharpener sharpens curved blades and lawn mower's blades without any problems thanks to its adaptable mechanism.

    Remember to always use it ON the blade, and not the opposite.

    @Guillaume This is they type of blade/lawnmower I need to sharpen. It can be tricky to get a good angle to sharpen. Your device looks like it may be just what I need.

    @connie

    Hello Connie,

    Yes sol.inge will work perfect on this type of lawnmower's blade.

    Just make sure to use the knife side, to use the sharpener on top of the blade -horizontally- to sharpen; here you will have to spin the blades as you sharpen since they are curved.

    Also, do not forget to rest the handle of the sharpener on the blade for a perfect use of our mechanism.

    Thank you, and do not hesitate to contact the team if you have any questions!

    @George

    Hello George,

    Some Japanese knives have only one bevel, as you put it, they have only one 'slope'.

    For these kinds of knives, I recommend to use the knife side, and draw very gently with the sharpener resting on the blade.

    Be very gentle with the Japanese knives as they have very fine edge, do not apply pressure at all here.

    The aim of sharpening is to restore the edge line, not take off too much metal!

    Thank you,

    As Mike says, you will get the best results on all kinds of serrated knives and micro serrated knives.

    Use the knife side, and remember:

    Serrated knives have to be sharpen slowly and gently.

    You will fell the self adjustable mechanism going up and down each serration without flattening your blade.

    So, when sharpening kitchen knives, just position the blade facing up, the most dangerous possible position, then the sharpen with your hand directly over the blade? This looks like quite a dangerous sharpening model to me. As someone who has worked in restaurant kitchens, I'd worry about consumer safety using this approach.

    5/11/2016 11:45 AM

    Hi Larry, of course everyone who uses Sol.inge, or any knife sharpener for that matter, should exercise extreme caution when doing so. Because of the handle design on top and bottom, your hand stays protected from the upward facing blade. You also don't need to apply much pressure to produce sharp results.

  • Jerrold
    Jerrold
    5/11/2016 12:54 PM

    @Mike I agree with Larry. Having worked with edged implements for decades, this looks dangerous as hell.

  • Mike
    Mike – Grommet Team
    5/11/2016 1:07 PM

    Hi Jerrold, really anything you do with knives is dangerous as hell if you aren't careful. Guillaume has designed a tool with safety precautions in place to avoid injury, the bar underneath the handle and the lack of pressure needed. The one thing he can't include, that everyone who buys this has to bring themselves, is caution.

  • Laura

    @ Larry and Jerrold...I've had a knife sharpener that works like this one for decades. I discovered that sharpener while volunteering in a soup kitchen, and I bought mine at a restaurant supply store.

    It's not dangerous because there's a guard between the blade and my fingers. You don't have bare fingers right over the blade.

    This sharpener looks like a more complicated version of the one I've been using all these years.

  • Guillaume

    5/11/2016 3:17 PM

    @Jerrold @Robin @Larry

    Thank you for your concern about safety.

    Let me explain to you why Sol.Inge is safer than any other sharpeners:

    For all other sharpening methods, the knife is in your hand and in motion all the time, as the sharpener is pinned down on the table.

    Anybody with a knife in their hands is more dangerous than a knife blocked on a flat surface.

    On top of that, it is impossible for your hand to be in contact with the blade while using Sol.Inge, even if you try hard.

    We have a clean track record in terms of injuries, and we sold hundreds of thousand units in France already.

    Thanks a lot!

    5/11/2016 12:50 PM

    Hi Sherri, we found that most people professionally sharpen their knives every few years. While that is still good practice, especially for very expensive knives, Sol.inge will help keep them sharip in between to avoid injury as my left thumb scar will attest to.

    @Allyson @Sherry

    Hello Allyson and Sherry,

    If you use Sol.Inge, you will restore the edge line of your knives, without damaging your blade or modifying it.

    A 'professional' sharpener using a whetstone no matter how skilled he is, will never sharpen at the right angle because it is virtually impossible to do it by hand.

    He will certainly get good results because he will use his skills, spend time on it and use different kinds of stones with various coarseness.

    But for home daily use, Sol.Inge will do the job just like a professional thanks to our new mechanism!

    Just follow the right sharpening steps for each kinds of blades.

    Thanks a lot,

    G

    Hello Robin,

    Thanks for your question.

    No matter what kind of knife you use, they all have a penetration point (the edge line) or, the fine end of the edge.

    The beauty of the self adjustable mechanism, is that the tungsten carbide plates are pinching the edge line of your knife, and the edge line only, without modifying the other data of the edge: angle, shape...

    Thank you,

    Hello Cindy,

    No! it does not sharpen ceramic knives or any ceramic cutting tools.

    Reason being, Ceramic breaks! and if you use Sol.Inge (or any other sharpener) you will scratch them and they will also nick and become serrated.

    I recommend you use a polish type sharpener, that works only with ceramic knives.

    Thank you,

    Is this any different in principal than the Samurai Shark they used to sell "as seen on TV"? I have one of those and am sorta happy with it, but if this improves on it in any way I'd be interested.

  • Mike
    Mike – Grommet Team
    5/11/2016 2:38 PM

    Hi Mark, Sol.inge works well with more types of blades and takes away the manual sharpening process of Samurai Shark. In a handful of reviews I've found online, it seems Samurai Shark has caused knives to be scratched and damaged as well which Sol.inge's design helps avoid.

  • Guillaume
    Guillaume – Special Guest
    5/11/2016 4:00 PM

    @Mike @Mark

    Hello Mark!

    The 'samurai shark' is not a bad tool, but let me explain why sol.Inge is better.

    Samurai shark sharpens at a fix 20 degree angle and consequently, it will put the same angle on all your knives: Japanese type, cleavers, peeling knives...

    Sol.inge will self adjust and never damage your knives, whatever the type or shape.

    The other big difference is that Sol.Inge has a dedicated scissors ans shears side.

    You cannot sharpen those tools the wrong way,it is safe, quick, and your get the best results.

    Our 5 carbide plates are of the highest hardness, and we guarantee them 10 years against wear and rust!

    Thanks,

    I just bought one of these and am looking forward to using it. I don't think it is correct to say every knife has a different angle. More likely, most kitchen knives have either a 15 degree or 20 degree bevel and the Sol.inge will accommodate either. Splitting hairs I know but just trying to be accurate.

  • Guillaume
    Guillaume – Special Guest
    5/11/2016 4:13 PM

    @Paul

    Hello Paul,

    Thank you for your trust.

    Indeed, every knive has a different sharpening angle, based on the metal alloy used and the function of the knife.

    It is difficult to know which angle is best for your knife, as only the knife manufacturer has the answer. Sometimes on expensive Japanese knife, you will find the angle mention in the back of the box 13 to 16 usually.

    For peeling knives, cutters, your angle will be less than 10 degrees.

    For kitchen knives, Japanese knives, between 13 and 20 degrees.

    For cleavers, axes... 25 degrees up

    With Sol.Inge, no need to worry about the angle, it is self adjustable.

    Thank you,

    G

    Hello Marilyn,

    I have just had a look at your cutting tool, it is true that it looks like a pizza slicer!

    Ok, so pin down you cutter with one hand on the table, the cutting edge facing you.

    The twist here, is that you will use your thumb to block the rotation of the blade.

    Then use the knife side of Sol.Inge, and draw on the visible section of the blade.

    Take off your thumb, rotate the blade, and repeat until the whole blade is sharpened!

    I hope it was clear enough,

    Thanks,

    Guillaume
