Sharpener Review: Lansky Diamond and Ceramic Sharp Sticks

I put my two Lansky SharpSticks to the test.


It has been a while since I have published a review. I am testing several knives at the moment, and am really just waiting on the fishing season to get into full swing so I can finish testing the Cold Steel Canadian Belt Knife and Wilmont Knives Wharny. I need to log some river time and a few trout with each to be able to say I fully tested them.

I purchased the Lansky Diamond SharpStick ($14.99)and Ceramic SharpStick a couple of months back and have been playing around with them some. Tonight, I decided to put them to a series of objective tests. I took 3 of the dullest mystery-metal paring knives from the box o’ knives that I mentioned in a previous post and got to work.

These things were DULL!

I started my testing by making sure the knives were well and truly dull. I cut several strips of cardboard with each, yielding some pretty horrible results. Not content to stop there, I used each as a scraper across the oak board you can see in the above photo. I confidently sawed away at my hand with each one without leaving so much as a scratch.

I started with the Diamond SharpStick. After about 4 minutes of persistent work, I tested it on the cardboard. It was not a perfect result, but the rod most certainly put a functional edge on the knife.

The diamond rods put a functional edge on the paring knife.


I was even able to slice strips of phonebook with minimal tearing.

I next tried the Ceramic SharpStick. This is a slightly finer grit than the diamond rod, and it showed. It definitely put an edge on the knife, but the results were still pretty rough.

Finally, I used just the coarse rods on my Spyderco SharpMaker. I know that this is not an apples to apples comparison. The SharpMaker is a system that is meant to put and set (with the fine rods) a razor edge on a knife. Lansky makes a sharpening system which while I have never used it, is very highly regarded and a more comparable system to the SharpMaker. That being said, many of you own a Sharpmaker, and can relate to my use of this control test.

As expected, the Spyderco put a very nice edge on the third paring knife. I didn’t even need the fine rods to know that the new edge on this knife was miles ahead of the Lansky rods.

The SharpMaker does a fantastic job and served as my control test.


As I said, not a fair comparison to the Lansky rods, but the SharpMaker really is the proper tool to actually put a good edge on an extremely dull knife. With the coarse rods alone, I was able to put an edge on a knife that was as sharp as many factory edges.

A more applicable test is what the Lansky rods will do with a moderately dull knife, such as the Wusthof’s in my knife block. I do not baby these knives, and while their edges were solid, they have seen many dishwasher cycles since the last time they were sharpened (with the fine rods on the SharpMaker).

Here, both Lansky rods showed their usefulness. First, I tried all three paring knives on cherry tomatoes. The diamond-sharpened one performed significantly better than the ceramic-sharpened knife. But neither held a candle to the Spyderco-sharpened one.

Both Lansky rods honed my Wusthofs to a very nice edge.


I then took my two Wusthof paring knives and put them to the test. I forgot to do a “before” test, on the one for ceramic-rod testing, but I can honestly say it was in the same condition as the other, and would have performed similarly.

Both Lansky rods honed the existing, sub-optimal edge to a greater efficiency, in less than 30 seconds of work on each of the Wusthof knives. The resulting tomato slices speak for themselves.


I like both of the Lansky SharpStick rods. While they are not able to put a truly great edge on a very dull knife on their own, they hone a functionally dull knife to a very good edge. Both enabled me to make much more precise slices with my Wustof blades.

Objectively, the diamond rod puts a slightly rougher edge on a knife. However, these micro-serrations aid in penetrating vegetable skins and the resulting slices were virtually indistinguishable. However, the ceramic rod honed an edge that was smoother to the touch than the diamond rod. Both were better than the “sharpening steel” that came with my set.

If I could only recommend one I would chose the diamond rod. The deciding factor was durability. This thing feels virtually indestructible. The ceramic rod is thinner and feels more fragile. If dropped, it would certainly break,.My only knock on the Diamond SharpStick is that it might be slightly thick for some knife blocks. I can put mine in the existing hole in my block, it is a snug fit. Your mileage may very.

While I have not done an endurance test, I cannot imagine the diamonds wearing out. If they end up wearing off in the future, I will publish an update. In the mean time I am giving this product the highest endorsement I can – I have swapped it into my sharpening block, and will use it whenever I want to touch up a knife before getting down to food prep.

    Those rods leave a lot to skill and technique, two attributes I lack, so I use the Lansky sharpening system to set up an edge, then their Turnblock Crock Sticks to keep it sharp. The Lansky Turnblock is similar to the Spiderco Sharpmaket, but at only $20+ it seems a good deal, and more compact

    nice real world assessment using cast off blades that are easy to relate to.
    our kitchen set is some various chine “sabatier” in a block with a steel hone that could stand to be upgraded. it keeps those and the flint stainless stuff ready for tomato skin. but it has some rough spots and a craplastic handle.
    go to for edge resto is the coarse stone on the smith triangle. the medium stone is awesome too, the hard arkansas has some vein flaws that hinder its usefulness.
    the gatco set that is designed much like the lansky style is very effective- five angles and three finishes depending.
    and my cutco v mirrors the sharpmaker somewhat. but the three sided rods have only one smooth side- are the ridged sides functional as well? i received it with no ‘structions and missing the fine rods which i would like to locate. holding a vertical angle sure is simple.
    finally there is the swap meet find old timer steel that lives in the tackle box. a flat bar that tapers at one end and stores in a leather sheath. that thing does nice touch up in the field.
    and when you mention those herter’s style canadian belt knives it makes me think of what we called murphy knives. i think they made them for herter’s, still available for fortyish with wooden handles and crafted on this continent.

    Vintage and antique sharpening “steels” (or sticks) perform quite well for my kitchen and field knives. All those steels are in good condition and were found at yard sales for 50 cents or less.

    It’s really a great and helpful piece of information. I am satisfied that you simply shared this helpful info with us. I utilize the Lansky honing framework to set up an edge, then their Turnblock Crock Sticks to keep it sharp. The earthenware pole is more slender and feels more delicate. On the off chance that dropped, it would unquestionably break.Thanks for this guide! I know a lot about pocket knives sharpener but I’m still more learning about Lansky Diamond and Ceramic Sharp Sticks. There’s so much information and varying opinions out there, thanks for presenting the facts and helping me to get a clear understanding of what I should be thinking about and considering for best knife sharpener purchase.Thanks again and keep up the good work.

    When I originally commented I appear to have clicked on the -Notify me

    There has to be a way you can remove me from that service?
