Greetings from Australia thanks for the add, first time knife sharpener with the exception of a steel oil stone and electric knife sharpener .

Ordered the KMFS system and thought I would give my first impressions .

Comes in a decent foam lined box, whether the latch survives multiple uses the jury is still out

Opening box was well packed and the sharpener system looks very very well made . I ordered the additional ceramic stones that come in 1500 2000 and 3000 grits , on top of the 240 600 and 1000 grit diamond stones. I also ordered the leather strops but forgot to order the diamond paste that comes with it.

Mounting to table is easy using a g clamp, I mounted sharpener on top of a bit of rubber so didn't scratch table.

Mounted a martinni fillet knife that has had a hard life being dragged through a pull style and electric sharpener but was recently sharpened on a tormic . Proceeded to work my way through progression of grits.

Passed the paper test but I feel like u should of maybe ground bevel flat as knife was catching through paper on all the chips from knife edge.

The stones I believe are used dry only , not sure if I am supposed to push them in One Direction or not but I was scrubbing them a fair bit trying to get a burr on edge with 240 grit stone .

I didn't use sharpee and an angle cube on its way as I am not quite sure how to use the the angle gauge supplied and how it's affected dependent on how high or low you mount it in knife clamp so just guessed.

The clamp on base stayed fixed as did the clamp that fixs knife via an Allen key .

Pretty happy so far with unit, very well constructed and great attention to detail ,and will update when angle cube arrives and I clean up bevel and resharpen , hopefully I get that hair removing edge I'm chasing
 
Thank you for report,

I must agree a lot of people is confused by operating angle guide,
I make some eng video, where I try explain function and placing.

I got from Stephen (England) operation manual updated, so I add it here
 
Instructions for use
SHARPENING KIT FOR SYMMETRIC HONING OF KNIVES
KMFS® sharpener

1. Introduction
Congratulations on your purchase of the KMFS sharpener! We wish you a lot
of fun in sharpening and great performance from your knives. This user
manual is intended primarily to familiarize you with the sharpening system
and provide recommendations that can facilitate working with it.
The sharpening system is produced exclusively in the Czech Republic from
premium materials. Each set is hand-finished and assembled with the utmost
detail for you, because we believe that only top-quality premium products
can lead to the perfect result of sharpening your knives.
All the information (including contact details) in this manual corresponds
to the state at the time of printing this user manual. In case of loss or
updating of the manual, this manual can be downloaded freely at
www.kmfs.cz.

2. General instructions
 The sharpening system is designed for honing all types of knives with straight, plain-edge blade type, not for use with serrated blades.
 The maximum thickness of knife blade that can be used with the supplied clamping screws is 6mm (approximately ¼”).
 Sharpening stones should be used dry, do not use water or any other lubricant.
• Clean the kit only with a dry cloth. The kit is designed and built as maintenance-free.
 Diamond grinding stones are capable of sharpening all knife materials - metal and knives made of advanced ceramics.

3. Important Notices
 Keep in mind that knife sharpening is inherently risky. Avoid making contact with the edge of the blade when setting up and using the sharpener.
• Never leave the knife unattended.
 The blade at the end of honing gets very sharp, keep this in mind to prevent injuries. Be careful!

4. Package contents
 Knife sharpening jig. Never leave an unattended knife in the jig.
 Two grinding stone carriers (stone holders).
 C-clamp for attachment to the table.
 Blade angle gauge.
 Allen key for blade clamp.
 Abrasive diamond stones.*
* Only included in complete packages.

5. Workflow
Remove individual parts of the system from the briefcase, the abrasive
stones can be placed under the bottom foam.
Place the sharpening jig on the edge of the work table so that the clamping
hole (in the blue cube on the underside of the blade clamp) is pointing
toward you.
Put the c-clamp into the clamping hole and use the plastic wheel to tighten
the c-clamp so that the jig is firmly fixed to the table and does not move.
Using the Allen key, loosen the upper screw on the blade clamp so that the
gap in the clamp is larger than the blade thickness you are about to grind.
Insert the knife into the blade clamp so that the blade is pointing upward
and the knife tip is away from you. Do not put the knife too deeply in to
the clamp. Keep shorter blades clamped as close as possible to the handle.
The clamp should be placed towards the middle of longer blades. Lightly
tighten the upper bolt clockwise.
Now tighten the lower blade clamp screw counterclockwise so that the blade
is held firmly and cannot move relative to the clamp. The lower blade clamp
screw is accessible through the hole on the right hand side, under the
upper clamp screw.
Now insert the two abrasive stones with the lowest number (the coarsest
stones) into the stone carriers. You should use two stones with the same
grit value.
Press the flap on the stone carrier and insert the grinding stone and
release the flap. The stone will now be firmly fixed.
Set the desired sharpening angle: by turning the blue knobs, you can either
increase or decrease the angle. The horizontal shaft is contra-threaded, so
adjusting either knob changes the sharpening angle on both sides by the
same amount. With every single revolution of the adjustment knobs, a sprung
detente latch automatically secures the angle setting. You can keep the
preset sharpening angle from the manufacturer or adjust it as needed. The
angle gauge is attached to the right movement screw as shown: the left side
is at the beginning of the thread, the right side of the gauge on the left
side of the brass bearing. The approximate angle is etched beside the
vertical surface in contact with the bearing. The actual angle will vary
depending on the depth of the blade being sharpened.
Place the base of one stone in contact with the heel of the blade. Now draw
the stone down, while at the same time moving the stone towards the tip of
the blade. Then, repeat this motion on the other side of the blade with the
second stone. Alternatively – or when sharpening a long blade – you may
prefer to move the stone up and down while gradually moving towards the
tip. In either case, you now continue to sharpen the knife by alternately
stroking each side of the blade with the stones, in order to keep the bevel
equal on both sides.
Be very careful to hold the stone carriers in such a way that your fingers
are kept clear of the knife edge.
Do not finish with the coarsest stone until the scratch pattern from the
abrasives reaches the apex of the cutting edge. For better visibility, we
recommend colouring the blade with a black marker. As you sharpen, the ink
will be removed from the blade. Once you have an even scratch pattern, and
all the ink has been removed right up to the edge of the blade on both
sides, you can finish with the coarse stones.
Fit the next finest stones (higher grit number). Using the same grinding
method, alternate between the sides of the blade as before. The aim is to
remove the rough marks from the coarse stones, replacing them with finer
scratches. Again, this can be clearly seen by marking the edge with ink.
Once all the ink has been removed, this indicates that the high points on
the edge have been worn away, so the scratches are no longer deep.
Now insert the stone with the highest grit number: the finest stone. Continue to grind the blade, alternating between the sides as usual. Again, you want to entirely remove the scratch pattern from the previous stone, and replace it with finer pattern from the current stone. As before, we also want the new scratch pattern to run right to the very edge of the blade.
Now you should achieve a fine edge with great sharpness.
Carefully release the knife from the blade clamp by turning the lower clamp bolt clockwise and put the knife in a safe place.

6. Maintenance and features
Cleaning and care
The sharpening system is designed and manufactured as maintenance-free, only dry cloth or brush cleaning is recommended after each use.
Details
Precise angle adjustment by 1.5mm on guide screw.
Contra-threaded adjustment system ensures that the sharpening angle remains equal on both sides.
The universal joint at the base of the guide rods has been designed to minimise the change of bevel angle that can occur at the tip of the blade when using other guided sharpening jigs.
Packaging:
Plastic case with foam lining
Material:
-Dural alloy ENAW 7075 T651 hard colored anodized
-Steel guide screw, guide bars and screws, stainless steel angle gauge
-Bronze guide bushings, guide bolt sleeves and hinged nuts.
 
Hi , what are the replacement stone options? I've done about 11 knives and the 240 grit stones are pretty much as coarse as the 3000 grit ceramics
 
Any recommendations for replacements, got a couple of cheapies off eBay but I don't see them lasting long
 
Depends on hardness and amount of materrial you grind away.
The biggest wear is on 240 because it is used to make new geometry.
Normal is about 50 unique knives on 240 stone (first sharpening).
For resharpening the stones last more.
Normal is about 200-500 sharpenings
(got this from most users)

This issue is normal on diamond stones, no way to avoid this..
 
Are the stones Edge Pro format with 45 degree bevels on the ends?
 
Not sure about dimension of Edge Pro format, yes there are 45° bewels on both ends

More likely 20mm wide Chinese edgepro format instead of 25mm standard edgepro format.
 
I went to your site. It said no sharpening products available. Is this the case at this time?

Looks like you have a new version with an interesting clamp. Is this available yet?
 
Hello,

Thank you for noticing,
Yes, the whole new system KMFS Rival MOA21 - user friendly sharpening system, patented clamping system,
available here ,
the price is terrible, but it is realy a lot of solid pieces of Ergal duralumin and bronze and a lot, lot of machinig.

Best regards: Vaclav

I like your paddle design, too bad you didn't use the EdgePro format. Your close but 1.2mm too long, EPs are 158.75mm long. A few years ago I tried to interest EP in me making a similar paddle for the Wicked Edge with EdgePro engraved on the sides in big letters but they weren't interested.

If my conversion is right your price is $658 + $20 international shipping. If this is correct then I think your price is in line. Is your anodizing Type III? If so how thick is it?
 
Thank you, -I decided to hold one line of sharpening stones (same thickness), then you have no need of readjusting angle, you just clamp and sharpen.

At this time we have blank stones for taping lapping films, or your own abrassive if you need.
Yes, we use only hard coat anodising. We use only Ergal 7075 T651 and hardcoat- normaly we are between 20-80 µm. We got the best results in our testing at this material and coating.

Yes, the price is correct, our basic sharpener is on 1/3 of this price.

Very nice.

It would be very beneficial if it could accommodate any stone between about 3.5" and 6.5".

If you guys could look into that, it would be quite popular.
