Sharpening Instructions

Always apply a few drops of Smith's premium Hone Solution to your stone before you start sharpening. The lubricant floats away metal and stone particles that develop during the sharpening process.


Mount T-Bars tightly onto the end of the knife clamp then screw a guide rod into the end of each stone bar.

Position of Blade

Attach the knife blade by loosing the front screw and red thumb screw of the knife clamp in order to accommodate the thickness of your blade. Attach clamp to back of blade at the midpoint of the blade. Seat the blade in the vise so at least 1/4-inch of the blade's cutting edge extends out beyond the end of the vise unit. Tighten front screw to hold knife in place and to lock knife into place tighten large thumb screw on knife clamp. Do not over-tighten either screw. Caution, do not attempt to sharpen your knife if it is loose in the clamp.

Angle Selection

After you have securely fastened your knife into the knife clamp, place the guide rod with stone bar attached to it through one of the slots in the T-bar. The two most commonly used sharpening angles include:

  • The lower slot sharpens at a 20 degree angle and is commonly used for quality blades and provides an excellent edge for these type of knives. This angle is ideal for kitchen knives.
  • The upper slot sharpens at a 25-degree angle and provides a durable sharp edge for most knives. This angle is excellent for hunting and all outdoor knives.
DFPK use
V-Lock vice holds your knife steady during sharpening
(view larger).
Sharpen Your Knife

Hold the knife clamp in your hand with the guide rod in the desired angle slot you wish to use. Holding on to the plastic handle of the stone bar, place the stone you intend to use on the knife blade near the handle of the knife. With smooth easy motions, push the stone across the cutting edge, working your way from the handle to the point of the blade. To sharpen the other side of your cutting edge, remove the guide rod from the slot, turn the knife and clamp over, place the guide rod in the same slot on the T-Bar you used on the other side and repeat the same sharpening process. Use the same number of strokes on each side of your cutting edge and sharpen both sides of your cutting edge before moving to the next stone.

Sharpening Serrated Edges

To sharpen serrated edges, use the blue stone bar with specially shaped triangular stone and repeat step four for each serration on the serrated side of knife only. Once you have finished the sharpening process you need to remove the small burrs that are created on the backside of our edge by removing our knife from the clamp and running the Fine Arkansas stone lightly over the backside of the cutting edge.

While the design for the Smith's sharpening kit is all it's advertised to be the manufacturing quality of the the kit I purchased in February of 2011 fell far short of the design. First the blade holder was clearly not symmetrical, so when you inserted the guide rods there was a few degrees difference between the two sides of the blade you were trying to sharpen. From a quick assessment on a sheet of graph paper it looked to be off by about 10% from one side to the other. Secondly the retaining nuts, or more accurately the spaces behind the retaining nuts in the hone were much shallower that the threads of the guide rods in my set. So when I threaded the guide rods into the hones the guide rods bottomed out and cracked/broke (quite easily) the plastic the retaining nuts were set into. On one of the hones the retaining nut wobbled so much that the guide rod was essentially useless.
I like the design, it's simple but effective but the delivered product is just crap.

I started with an old Chicago cutlery chefs knife that I'd given up on. After running it through the 3 cycles it was restored to good use. You can buy cheaper and easier to use sharpeners but none that will give you a perfect result every time. This system holds the blade at a constant angle eliminating human error. There is a setting for kitchen knives and one for outdoor/hunting knives. It even has a stone for serrated edges. Now I use it on my expensive Japanese knives and they stay razor sharp.

I have been working with the Smith kit for over a year now. To begin with the singular most important piece of having a truly sharp knife is getting the edge set at the correct angle and keeping it consistent throughout the blade. In most sets like this there are often complaints about the clamp that holds the blade and allows for the guide to set a consistent angle. The clamp in this kit is great, holding the blade tightly without damaging the knife or loosening during sharpening. That being said, the one down side is that it only offer 20* and 25* guide angles. This means that for those among us working with high quality Japanese knives we have to settle for 20* versus the more desirable 16/17*. While it is still possible to get a knife razor sharp at 20*, there is a notable difference. While working with the set on high end knifes, I was afraid that the diamond stones would not stand the test of time, especially in a set that is so reasonably priced, after a year + I can definitely say that they will hold up. They are still able to re-profile blades that get nicked and are not showing any significant signs of wear.

Overall the quality of the set is good:

+ Durable stones
+ Great clamp
+ True edge at 20* & 25*

- No 16/17* guide on clamp

I have been sharpening knives with combination of by hand and using one of the sharpeners where you swipe the knife through them. In general, the results have been pretty unsatisfying. I was not sure about this kit, but I really wanted to get some sharper knives. This kit did a great job on the knives for non-serrated blades.

The process is that you attach the clamp to the back of the blade and screw one of the hooked rods into the end of the sharpening stone. Then the hooked rod holds the angle of the sharpening stone and blade constant as you sharpen the knife. I actually found sharpening to go pretty quickly and by holding the angle constant, the knives ended up quite sharp.

The stones are about as small as they could be and sharpen the knives, but they are adequate. The kit does nothing to make sharpening safe, so you are still responsible for not getting cut.

I played around with sharpening some serrated knives, but this was going to be pretty difficult as the angles of the clamp and sharpener don't always work out so you have to play around to get the angles right. There are probably better ways to sharpen serrated blades. The system was not compatible with several serrated knives that I have.

Overall it is a very cost effective sharpening system.

This is a great product that does exactly what it says. I had some knives that I wanted to throw away because I couldn't get a sharp edge on them with any thing I had. My husband has put a completely new edge on them. It's like having brand new knives. However, it takes a good amount of time and effort to get there.

For the last two years I have been using the Lansky system to sharpen knives. It was just the oil stone version. I thought I would upgrade to a diamond stone system. The Smith's system was on sale at Lowes for half price, so I grabbed it.

The first day, when I screwed the handle into the back of the course stone the entire plastic frame cracked, rendering it useless. I glued it back together and sharpened all our knives with the Med stone. It did a good job, and at the correct angle, but the knives were not as sharp as I was used to getting them. The Triangular shaped Arkansas Stone for serrated edges was out of shape and had several chips in it, rendering it useless. You can not push on this system because the supports are also made of plastic. Until I get a better sharpener, I am going to use the old Lansky solid metal support with this Med stone sharpener. I would not buy this system again.
