Best purchase I every made. while my knife doesnt cut a fine layer of tomato without touching it, it became as good as it was when I purchased. I recommend users to learn how to properly sharpen the knife. It took me about 30 minutes to sharpen a single knife to what it is today. The knife gets really sharp. Also, with use, the surface gets uneven. I recommend you draw a grid in pencil and then file using the grinder stone until the grids disappear. This ensures the surface remains flat during all use.
There are no lengthy explanations needed to describe the Lansky 8” Ceramic Sharp Stick sharpener. It’s an old-fashioned device comprised of a hardwood handle and ceramic sharpening rod. That’s it. Sure it’s not going to create an absolutely picture perfect edge down to the last micron but it will keep your knives really sharp and do so for next to nothing.
Sharpening is really two processes: Grinding and honing. Grinding is simply the removal of metal. Honing is a precision abrasion process in which a relatively small amount of material is removed from the surface by the means of abrasive stones. Once you have the right shape, usually using a more aggressive grit, you then switch to a finer grit to hone the edge.
Why, then, do so many of us shy away from the task? To put it bluntly, it's because it's a rather daunting process for the beginner. Your image of knife sharpening may consist of a hyper-masculine chef slashing away violently at a steel rod (we're looking at you, Gordon). Conversely, you might have seen cooks meticulously and methodically stroking their blade up and down a Japanese waterstone with more intricate attention to detail than a Flemish landscape.
The Juuma sharpening and honing stones offer a simplified working principle while at the same time ensuring the highest possible quality in the offered grits. Juuma Cobalt Blue stones are made of an aluminium oxide and a bonding agent. Adding cobalt serves to slow stone abrasion and increase the speed of sharpening. The speed bonus is especially marked when stoning blue steel (blue paper steel that is often used for Japanese planes and chisels). The cobalt gives the stones their blue colour. Juuma is our proprietary brand. Juuma sharpening stones are produced by a renowned Japanese whetstone manufacturer.

The toughest angle to master is the angle at which you'll sharpen the edge of the knife. For a Japanese knife, that should be around 12-15 degrees. Before you reach for the protractor, a good test is to get roughly half an index finger's gap between the spine of the knife and the stone (see above). Remember to remove your finger before you start sharpening. For a Western-style knife, you want an angle of about 20°, so raise it ever-so-slightly higher.
Stropping a knife is a finishing step. This is often done with a leather strap, either clean or impregnated with abrasive compounds (e.g. chromium(III) oxide or diamond), but can be done on paper, cardstock, cloth, or even bare skin in a pinch. It removes little or no metal material, but produces a very sharp edge by either straightening or very slightly reshaping the edge. Stropping may bring a somewhat sharp blade to "like new" condition.
Grinding is generally done with some type of sharpening stone. Sharpening stones come in coarse and fine grits and can be described as hard or soft based on whether the grit comes free of the stone with use. Many sources of naturally occurring stones exist around the world; some types known to the ancient world are no longer used, due to exhaustion of former resources or the ready availability of superior alternatives. Arkansas, USA is one source for honing stones, which are traditionally used with water or honing oil. India is another traditional source for stones. Ceramic hones are also common, especially for fine grit size. Japanese water stones (both artificial and natural) come in very fine grits. Before use, they are soaked in water, then flushed with water occasionally to expose new stone material to the knife blade. The mixture of water and abraded stone and knife material is known as slurry, which can assist with the polishing of the knife edge and help sharpen the blade. Generally, these are more costly than oilstones. Coated hones, which have an abrasive, sometimes diamonds, on a base of plastic or metal, are also available.
When you want to learn how to sharpen a pocket-knife on a sharpening stone, your pocket knife isn't going to get sharp in one stroke. You have to have at least a stone bar that's the minimum of 2x6 inches in measurement. In general, it'll help make the sharpening of the blade easier. When you sharpen it on a stone, you have the three main options: ceramic stones, whetstones, and diamond stones.
Not sure why I bought this item and then I received it. It has a bit of a 'cool' factor and is well made. I took the sharp edges of the stone as they were a bit uncomfortable on my chest but have since been wearing it a lot. Used it to put an edge on some workmates knives and to tickle up my own daily use knife. I like it, it is a bit different and useful.
One of the combinations of stones that I was introduced to several years ago is a unique one, it is a 500, 2,000 and 16,000 grit combination. I was apprehensive when I first tried this, that was thousands of knives ago, it works, it is fantastic combination. It is unique because the traditional way of thinking is that we should be doubling the grit sizes as we sharpen, for example, a 500 grit stone should be followed by a 1,000 grit, then 2,000 grit. This line of thought is meant to be flexible, it is a general rule only, I have broken it countless times.
This package includes a bamboo base to hold the stone, a premium quality whetstone (#1000 / #6000), a simple instruction manual, a knife sharpening angle guide and a detailed eBook that will help the beginners to learn the basic and advanced tips about effective knife sharpening.This special stone has versatile uses. You can use it to sharp scissors, kitchen knives, hunting knives and pocket knives too.
Let’s talk about the tip of the knife, the burr needs to be formed here as well. Here is a simple trick that works, I like keeping things simple. As you get to the tip area of the knife, the front inch, raise your elbow so that it is parallel to the ground, you can also raise your sharpening angle very slightly but just raising your elbow will perform wonders and likely eliminate the tip sharpening area issue, it is an issue for some.
I recommend keeping two stones in your kit. One with a medium grit (around 800 or so) to perform major sharpening jobs, and one with a fine grit (at least 2,000) to tune the edge to a razor-sharp finish. For real pros, a stone with an ultra-fine grit (8,000 and above) will leave a mirror-like finish on your blade, but most cooks won't notice the difference in terms of cutting ability.
However, because the Belgian Blue stone generally occurs in relatively wide columns with much thinner layers of Vielsalm Coticule on either side adjacent to the slate, the Belgian Blue stone is more plentiful that Coticule and thus, it’s somewhat less expensive. But, it’s also somewhat softer than Coticule and is not divided into different grades as Coticule is. Furthermore, because it is a softer stone than Coticule, it is sold without a substrate layer.
