The word “Novaculite” is derived from the Latin word “novacula”, which means “razor stone” and is essentially a metamorphic, recrystallized, variety of Chert composed mostly of microcrystalline quartz that is found in the found in the Ouachita Mountains of Arkansas and Oklahoma and in the Marathon Uplift of  Deposited in the Devonian Period and the early Mississippian Subperiod some 410 to 325 million years ago and subjected to uplift and folding during the Ouachita orogeny of the Atokan Epoch (early Pennsylvanian Subperiod), Novaculite is a very tough stone that is resistant to erosion and thus, the various layers of Novaculite stand out as ridges in the Ouachita Mountains. Thus, due to both its availability and its composition, it has been mined since ancient times for use as arrowheads and spear heads as well as in more modern times for use as sharpening stones.
2. Although I’ve been sharpening knives for a while, I never could get a knife sharp using the freehand method, I’ve had to rely on various jigs to set & maintain a constant angle to the bevel. To begin with, the Lanksy knife sharpener kit was my main tool, but then I found a South African jig made by Warthog Knife Sharpeners. I still have their first model, which, if memory serves me, came out in the late 1990’s. This has since been upgraded & is supplied with a diamond stone, which is worthless unless it’s going to be used for ceramic knives. However-the Warthog & the Warthog Multi-Blade’s modus operandi has the knife moving ABOVE the stone, unlike the Lanksy / Edge Pro / Edge Pro Chinese copies & variants. ( No oil / water dripping off the stone from above the knife). Also, the Warthogs use any bench-size whetstone available to its owner, a very big plus if you want to use your grand-dad’s old Arkansas stone.No tie in having to buy the manufacturer’s specialised stones which work only with one type of sharpening jig.
I bought these knives based on the reviews on the web. As you can all see, the reviews are very positive. So, I purchased these with VERY high expectations. I was reluctant based on how expensive these knives are. After using them now for several months I am blow away by the quality of these. It has changed my whole view of how important great knives make to my meal preparation. I can say without reservation that these knives are a bargain. These are a great investment in yourself and your family. Man, are these sharp! Recommend these without reservation.

1. Diamond Stones. I’ve used two, many years ago, to sharpen steel knives & found that the diamond coating wore away. They did work well at first, but then I was sharpening on the backing material. This puzzled me, because diamond is harder than steel, but have only recently read that the diamond particles are torn off the backing material because they stick to the softer steel. Diamond stones are recommended for sharpening ceramic knives only. This info about diamond stones & steel knives I got from an Edge-Pro article.
However, due to limited natural deposits and extensive quarrying over the centuries, true, high quality, Japanese water stones are now few and far between and are very expensive. Thus, various companies are now producing synthetic Japanese Water Stones which generally have a more consistent composition and grit size than natural stones as well as often begin somewhat harder and thus, lasting a bit longer; not to mention being cheaper to purchase.

If your tool is badly worn out or have a very dull edge, then use the coarse side of the Lansky Puck first to remove the unevenness. Next, apply the fine side of it to give a smooth finish. If you only need to polish it a bit, then there is no need to use the coarse grit instead use the finer part. As it is very small in size, you can carry it with you everywhere you go.
Place the index and middle finger of your other hand on the tip of the blade. Apply pressure and swipe the blade down in a pulling motion. Release pressure, and move the knife back up to your starting point. Apply pressure only when stroking down; otherwise, you’ll risk cutting into the stone. Repeat the up-and-down swiping motion; with each swipe, inch your two fingers along the blade, in the direction of the heel. When you’ve reached the heel of the blade, use the index finger of the opposite hand (which should already be placed on the heel) for extra support. Run a finger along the opposite edge of the knife. There should be a slight ridge, or burr.

Prior to using any kind of sharpening stone, it is advised that individuals soak the sharpening stone in light machine oil or household oil for at least 12 hours before being used. Before being used, it is advisable to wipe the surface of the sharpening stone to get rid of grime, grit or dirt that may have accumulated overtime during the time of storage.
