The correct hone for Nikasil.

Only to be used to deglaze the cylinder.  so keep in mind when you use it, also clean up jug with WD 40 & a clean cotton towel till it comes out clean. ( use a white one, )  you don't want anything left behind !

Great addition for the 3M 39045 Headlight Renewal Kit, use it in the refining process before polishing lens for a great, crystal-clear result.
(Tamper it with water exactly as with the original P3000 Trizact disc incluided in the kit)

Worth the money.  The sharpener does remove small nicks on the blade.  It also restores the edge to near factory sharpness.  I'm not certain how much sharper factory sharpness really is, but within a week or two of use, my newly sharpened Kyocera ceramic knives are equivalent to a new knife used the same way.  I like the product mostly because the alternative is spending $10 plus postage and insurance every time I want to refresh my knife edges.  Since I use my ceramic knives every day, they probably need to be sharpened 3 or 4 times a year.  Clearly the sharpener pays for itself and I don't have to wait for my knives to be returned from the factory.  I also like that the diamond wheels can be easily replaced at a reasonable price.

This is an excellent product and in opinion beats the hard plastic model.  I now have one for each of my Nikon lenses.

I have at least $1K invested in other so called "sharpeners" and have been unable to put anything close to a factory edge on my knives. I had been relegated to handing them off to a "professional" who would hit them with a belt sharpener to produce a serviceable if not inconsistent edge.  I have the coordination of a blind donkey, but within 1 hour was putting factory edges to shame. Check out the videos online like the ones by Nut Fancy. That is exactly how it works. Start with a few stones and then add as you need more. I've added a 1,000 grit (almost mirror polish) and also a 125 grit to re-profile. It's very well made from high quality materials and the stones are very good as well. When I bought it, I had hesitations about spending so much, but all things considered it's actually a bargain.

First, I didn't buy this product from Amazon (sorry 'bout that).  Second, I wrote this review originally as a comment on somebody else's one-star review, then realized few people would read it there, so I decided to repeat it as a review, not just a comment.
--------------------------------------
I've used several of these small plastic Gerber (now Fiskar) knife "sharpeners" for about ten years, with good results -- both the diamond-dust (dark grey rods) and ceramic (white rods) varieties, although I prefer the ceramic ones -- they are a bit finer, and easier to clean when they get full of steel dust. The main reason they are graded as poor by so many reviewers is that, to be honest, they are NOT much good for sharpening a truly dull blade -- for that you need a series of good stones (and a guide-tool, or a lot of technique), or a good sharpening system like those made by Edge Pro (either the Professional or the Apex) or the knife and tool sharpener made by Work Sharp. Those are really fine systems, but they require you to pony up some serious money. However, these little Gerber/Fiskars tools are very good for touching up a blade that is already fairly sharp, but which has lost its fine edge. They will not give you the extreme edge provided by a super-fine stone, or by any good sharpening steel, but they're good for QUICKLY touching up an edge during a tough chore like field-dressing an elk, without having to carry a fine stone or a steel around. When I'm hunting, I usually do carry a small Gerber steel, but whatever, it's nice to know that I ALWAYS have one of these little gadgets in my pocket to keep my knife (almost) razor-sharp.

...And by the way, the complaint about the 40-degree V between the rods?  That **IS** the correct angle. Usually, with a good steel knife, I sharpen at 18 degrees ON EACH SIDE OF THE BLADE, for a total edge angle of 36 degrees. The 40-degree angle on these little tools ensures that I am only honing the edge, not the entire blade.

A good value, but keep in mind that a medium grade sharpener is quite aggressive...if you need to put a nice edge on a blade that is already in fairly good shape, use a fine grade diamond hone.

Having owned a variety of knife sharpeners, I finally bought this one which doesn't require a degree from Caltech to use. If you use it the way you should   which is without pressing the knife down on the cutting wheel it will produce a very sharp blade without having to resort to the voodoo tactics required by other sharpeners like cutting stones and cheap products that use industrial diamond that operate manually. There's probably no doubt that this approach, which is typical of sharpeners that have been sold for many years, no doubt reduces the life of the blade somewhat, but that import depends on how you sharpen the knife. It's a good product, it works well, and it's well priced.

Good product for sharpening larger knives and garden tools.  Coarse/Fine double side works well for knocking down dings and finish whetting.  Fits the hand perfectly and with the proper technique it's impossible to cut oneself.

I only wish they made it in a finer grit

As reference, I have been sharpening knives for 30 years and have a box full of sharpeners.

Quick note: If you are only going with ONE double sided sharpener, I'd suggest going with the Red/Green version (Fine/Extra Fine), as it will quickly sharpen a duller knife with the Red Side, and then refine the edge to a good useable field edge with the Green Side.

If however, you already have the equivalent of the "Red Side" (a medium grit), then I'd say go with this model here, as it not only provides a good field edge with the Green Side, but then provides a final, well honed edge with the Tan Side.

I already have the Course (Blue) and Fine (Red) single sided DMT Diafolds, which do a great job for rough and dull sharpening needs. The EF and EEF grits on this model let me spend plenty of quality time with my knives in hand, sharpening to perfection!

Unlike a few reviewers here, I find the EEF side to be quite useful for taking the final wire-edge off the bevel, which is more difficult with the lower grit (higher coarseness) of the EF.

Stay sharp out there! ;-)

Just received this kit to use with a Nikkor 18-140 DX mm lens and a Vivitar 500 mm manual lens. Very few problems using either adapter and I really needed the filter kit. You will experience a slight loss in quality using these lens kits due to the fact you're shooting through additional layers of glass. That's another thing. The lens kits are glass and not plastic as found in many of the less expensive kits..

Blades I ordered with this arrived sharp so I did not need to use it but the dual grit will be great for honing when required. I alsol like the feel of it in the hand. It seems like it will be easier to use than my flat stones

this honing tool works great when rebuilding engines and does the job well. i would recommend this for the people who can use it and know their going to get their money's worth out of it.

Just what you need to finish off the blade of any thing you are sharpening.  Lansky is a product you can trust.

I've used a lot of sharpeners in my life from manual to electric and this is the first that really excels.  Sharpens Japanese-style knives with 15-16 degree bevels perfectly with only a few strokes and is also very successful in converting American kitchen knife bevels to the Japanese angle and putting a razor sharp edge on those too.

SpyderLensCal is wonderful!! What a simple, elegant solution to testing focus. I can't tell you how often I shoot with my 70-200 f/2.8 lens wide open for tight portraits. I can't say I always get the focus correct, but now I know the problem is me and not the camera/lens because of testing with SpyderLensCal. Fortunately, my equipment is all working properly, and knowing that adds a lot to my confidence level when shooting at wide apertures.

Setting up SpyderLensCal took only moments and I was able to check all of my lenses in a few minutes. I'll confess that in the past I have been what a friend of mine calls a "newspaper photographer" - taping a newspaper to the wall and shooting it wide open! SpyderLensCal is far more accurate because I can see exactly how much front-focus or back-focus I'm getting. This is particularly useful with today's high-end cameras which allow you to adjust for any error in how the lens and body are working together.

Bottom line: Another great product from Datacolor!

BUY THIS, or the clamping one if you are planning on using a Lansky sharpener
