I got this knife sharpener from George at S.T.A.T.E.S who is the American dealer for TechStudio who makes the K01 K02 and K03 knife sharpening system's,I'm also going to say that dealing with George was great and you tell he is a very honest and trustworthy person and some I consider a friend,George started bringing in the TechStudio line of stuff because he could see from post's on the bladeforum that people were not wanting to have to import them from Russia directly and decided to become a dealer to help people out,also George lives in the states and has all of his life he has spent a lot of time in Canada at the Michelin Tire Plant in Nova Scotia as a Scientist. The first thing I must say about the K02 is that everything is very well and precisely made and you can tell it was made by people who are machinist's first and foremost,the fit and finish and how everything moves was just perfect and that's what you'll see other people saying about it on the bladeforum and youtube. That's a basic overview of the system and I'll go more into detail,that is the bag and stone's you get with the system you get a 120 220 400 600 and a 1000 grit stone they are also FEPA grit rated stones witch mean's the 1000 grit included with this system is a finer grit then a 1000 grit Shapton stone. Also the bag that the stones come in are also great and I liked the bag so much I ordered 4 more and they cost 10 bucks each I think,also George does not stock to many extra bag's yet as he is still feeling out what the market want's but he can order them for you if he is out of stock on them. Now I will go over a few thing's about setting up the K02,there were a few spot's in the manual that were not cover the best but over all the manual is very clear and easy to understand. The Crossbar is very easy to setup and the manual covers that pretty well so I'm not going to say anything about it but as you can see I have mine setup so that if I put it on either side the Angle Cube reads zero. Next is how to setup part of the K02 I don't has a name so we will call it the zeroing out block. If you notice how the Angle Cube is placed in the same direction on the back end of the K02 as it is when place on the zeroing out block,what you do is zero out the Angle Cube on the back end of the K02 like I have it sitting on it and make sure it's reading zero then move it to the front of the K02 and set it on the zeroing out block,next thing you need to do is adjust the left to right or Horizontal direction of the block they say in the manual if it is out by .3 degree's that's fine but I made sure to get everything on mine reading zero. The easiest way to adjust the horizontal on the zeroing out block is to remove the top center screw Blue locktite it then put it back in and tighten it just so you can move the zeroing out block side to side but not so loose it wants to move around to much this will make thing's easier,now zero out the Angle Cube at the back end of the K02 keeping in mind the direction you need to put it on and put it on the zeroing out block and hold the block by the side's and adjust it until it's reading zero then remove the Angle Cube and while still holding the block and tighten the center screw and re-check the block to make sure it's still reading reading zero. Adjusting the zeroing out blocks vertical this was the part they did not cover to much in the manual they don't show putting the Angle Cube on the K02 like I do in the pictures below and zeroing out the Angle Cube witch has lead a few to set theirs up by zeroing out the Angle Cube in the pictures above and not like the pictures below.Also when adjusting the vertical there are 2 screws on the bottom side and of the block and that is how you raise the front and back end of the block up and down,I also removed those screws as well and Blue Locktited them before tightening them down for good. The reason for going threw all that was mentioned above is so that when you sharpen and want to set your angle you'll grab the Angle Cube not included with the kit and zero it out on the zeroing out block in the same direction as I have it in the 3 pictures above,then once the Angle Cube has been zeroed out you place it on the guide rod where I have it placed in the picture above. Next we will look at the flipper mechanism and how to adjust it this part was really well thought out and works flawlessly,also it should be noted that the central shaft ride's on ball bearing's and so does the cross shaft part of the flipper those aren't wheel's those are ball bearing's that act as wheels also. See the wheel or knob whatever you want to call it that my finger is pointing to that's how you adjust the holding power so the crossbar does not flip around on you all the time. The ball bearing's that act as wheel's on the cross shaft are now left to right in the picture above. Now they are up and down and you can see the de-tent's they drop into when the crossbar at the front of the K02 is turned to rotate the knife. Now well look at how to adjust the angle at witch you want to sharpen at. See where my finger is pointing at the knob that's where you will make your big adjustment's and slide the mast up and down to do so.
