This is a marvelous sharpening system. It is inexpensive and although won't put as nice of an edge as the Norton Waterstone system Norton Waterstone Starter Kit: 1) 220/1000 grit stone and 1) 4000/8000 grit stone, 1) SiC flattening stone it is a lot cheaper. I like these and use them for a convenient portable sharpener. I have sat in coffee shops and such and sharpened with these because they fit so well in a pocket. They don't require any lubricant but it is best to rinse them off after use (I used the drinking fountain at college) although you can do several uses and just wipe them off with your finger, water rinsing only once in a while.

OH I LOVE this set. WONDERFUL!

First of all, it's a DMT product, and their diamond crystals are superior to the competition to begin with.
Normally, diamond sharpening stones have the characteristic honey-comb appearance. The purpose for this is to help remove the metal dust created by the sharpening process. The dust falls into the honey-comb pattern, keeping the cutting surface clear.

That's great, and it works very well on knife blades. But that pattern is a problem when sharpening tiny things, and pointy things. Anything small enough to partially "fall" into a honey-comb hole pattern requires a continuous sharpening surface, like these!

I have only had this set for a few weeks, and have used them a zillion times.

Most recently, last night. My wife shopping (Amazon, naturally) for yet another pair of tweezers.
I asked her to show me the "dead" ones, and she brought down her tweezer grave-yard box.

I bought this little kit in order to have a super lightweight and small size diamond sharpener I could keep in my pack or wallet and never know it was there. For that purpose they are great. The coarsest one is still really not coarse enough to put an edge on a super dull knife, but you shouldn't be venturing out with a dull knife anyway, and it's got more than enough to grit to keep a sharp knife honed up during use.
