Using a Jig for Bench Stones

What you are looking at it is the core metal and the softer metal cladding, which is grey, which are one continuous bevel. There is no burr, but there is some lint on the knife edge. I assure you that there is no burr on the edge shown, since this edge was able to push cut paper well over an inch out from my hand.. I did not take the photo or else I would have removed the lint first. Double bevels and big metal burrs are unacceptable and neither are shown in this picture. Please look more closely at the photograph. This isn't something my device or the EP does.

What is edgepro's warranty? I have never purchased one of their units. I'm up to 14 postings and don't know what a sponsor is. If someone else could chime in on this one regarding the usual custom here, that would help.

This picture has multi bevels and burrs, no?
 
I think you have a nice machine there KssKss! It just might be alot better than the famous Edgepro. Not having a 90 day warranty is no big thing to me.

If your device works as good as you say it does nothing else is needed!!!!

Good Work,

"This picture has multi bevels and burrs, no?"

No definitely not. What you are looking at is a single bevel, encompassing the softer metal and the core metal. This blade, and many other blades have this clad construction. The purpose of this is to have a hard core which actually is the very edge of the edge and is harder but more brittle and it is surrounded by a softer less brittle metal. This gives the best of both worlds a sharp edge and a knife that is easier to sharpen and less brittle. For traditional blades a kasumi design has the hard steel as the flat back of the blade which is the actual edge and a piece of softer cladding in the front. Most raditional Japanese knives are made this way, with the exception of honyakai knives, which are usually quite expensive and often quite brittle.

What you are reading as burrs are dust particles. Note that you can see these particles not just on the edge but all over the blade. In neither case are they burrs, but are probably lint from the knife being wiped off with a kitchen towel. It's an easy mistake to make. You would actually be surprised how much of this there is out there. I would hazard a safe bet that you would see this on most of your knives if I was to pull them out of your rack or drawer and photograph them at this high a magnification.

"There is a 90 Day return Policy & a Life time Guarantee of the Edge Pro Systems"

I can't match this. My volume is small and my profit margins border on nonexistant so far, so I just don't have the deep pockets or profit margins to offer this sort of warranty. I can't open myself to a permanent level of liability. I couldn't give this kind of warranty on a 2 x 4 piece of wood or a nut or bolt. If the issue is requiring that level of product reassurance rather than the additional capabilities of this device, then it would be best to hold off on purchasing one of my devices. After I have a couple hundred of these devices out there, I might have the cash flow to do this, but for now it's just not possible. No hard feelings and I appreciate reviewing the device with you.

Here's an adjustable jig I made using an artist adjustable triangle, some small sheets of plexiglass, and epoxy. It works pretty well and is easy to set up. I can put different stones on there too. I use waterstones and I do have to rewet the stone often.

The only drawback is because the bottom of the L that the stone sits on isn't touching the ground, it rocks slightly if too much pressure is applied. That's why I slid that little plastic rod under the foot rest of that L, acting like a shim. As the angle changes for sharpening, the space between that foot rest and the base changes too—so you need different size shims to slide under there. That rod and a chopstick has worked for me since I don't veer outside the range of 7-25 degrees.


You can get an adjustable triangle at any art store that sells graphic design or drafting materials. I got it here: http://www.pearlpaint.com/shop~parentID~1987~categoryID~1986.htm . Here's a screen shot of that page and you can see the photo of the triangle fresh from the box. I cut mine down so I can have a place to put my hand to steady it as I sharpen.

Too bad on lack of warranty Ken. You will offer nothing?

Oh what is that pipe for hanging off the back of the jig?

Thanks
 
I think I like the EZE Sharp best at this point. It is cheapest and is smaller than ken's device and takes big stones too. I don't have to have a special table set up just for this sharpner like for ken's device.

I see two shiny bevels. The light refelcts differently for both bevels. I'm not talking about the dark section. Look close you can see it too. Also I've never seen shiny dust particles before. I think these are big burrs.

Here's a closeup from the picture. These are dust particles, plain and simple. When the light hits them right, they can look like shiny particles These are dust particles. Unfortunately this picture has lots of dust particles, even clumps of them. You can choose to believe that I purposely showed a picture of a knife with big honking burrs to discredit my device and all similar devices or try to figure out just how difficult it would be to even PURPOSEFULLY produce burrs like you are imagining I would have in this picture. I've inspected this edge at 200x magification. There are NO burrs here.

Regarding this multiple bevel concept. It's just this simple - you grind away at a given grit with a stone until you achieve a flat plane with all the scratches previously removed. Even if you are handed a knife with bevels all over the place sharpened by a drunken newbie, this device will level them out. If the bevel angle is measured accurately (I can measure this to less than 0.1 degrees using a more expensive angle measurer) you will get a flat bevel at that angle. In this case, the sequential stones are all of the same thickness. I'm not seeing what you're seeing and under much higher magnification the surface is a single plane. You are welcome to come visit me to see this for yourself. I'll bring out the scope and I'll clean the blade off with lint free kimwipes to get a finer picture.

I've given you examples of how much I have 'backed up the device' in terms of a warranty. This is a small garage style operation. I would suggest that you purchase one of these other devices first and if they are satisfactory to you, that's fine. If, after using them, you see what I see in my device, I'll look forward to doing business with you.

As for burrs, getting them or the lack of removing them isn't the fault of any system no matter what the system is. It is the fault of the person doing the sharpening. It is just silly to try and blame or defend a system for a burr.

This is true. You may wish to intentionally create a burr to determine when the two sides meet into an edge. If you continue past the point where the two sides of the edge meet, you generate burr. My personal style of sharpening is to minimize burr formation, but you are free to produce excessive burr either with any of these devices or freehand or minimize it.

Has anybody had anything to do with this system?

Appears you can use any benchstone and is capable of sharpening any size knives

I have one. The clamp that holds the knife does not give the same angle when it is turned around to do the other side. This means that the angle has to be adjusted evry time the knife is turned around which is a PITA. Another problem is of seting the stones in the holder which is another huge PITA. I made a stone holder for mine that uses Edge Pro stones. Much beter.

In the end a very good sistem but not as you buy it.

Why so hostile? I just asked some questions about your device and pictures and you got all upset. This doesn't show good customer service. I can only imagine what it would be like to have a problem with your device when you get so upset from just simple questions. Looks like my questions were a good idea because I found out you are not easy to talk to. Sorry for getting you so hot. Maybe you need to cool down Ken.
 
Did you join BF just so you could troll, Knifedude? That's what it's starting to look like. Yeah, you were just honestly interested in the PSD.:jerkit:
 
Bob, I joined for the reason I said. I was happy to see the maker of a device posting here. I asked questions because I want to buy one of these things because I can't sharpen good with my hands. I'm sorry you feel like I'm a troll. I'm just a simple southern man who wants sharper knives. I'm just glad I found out that Ken the maker is a mad man before I buy from him. I don't need to buy a device with no warranty to have the maker get upset with me for no reason. I will stay here to talk about these devices even if you think I'm a troll.

Thank you
 
I still have more questions to ask.

Does the ken's device scratch the blade from metal and water under the knife? I hear that EdgePro does this so maybe Ken's does too?

Sorry again if this looks like I'm a troll. I just want to buy the best device for my money.
