I have wanted a Wicked Edge sharpening system ever since I saw it for the first time. Problem was that I just didn't have an extra 250 dollars to invest into a sharpening system supporting a wife and two children on a single income. I decided that I was going to attempt to make my own after getting the idea I can use the Smiths clamp that came with a sharpening kit my wife got me as a gift. I also have access to aluminum at work, and a mill. This is not to be considered as a how to guide to make your own, just explaining what I did and how it works. Please be sure to read the conclusion of this post.

We had some very tight tolerance 1 inch Aluminum Square bars left over from a project and my boss said I can use it. Here is the piece I started with:

I used a drill press and drilled a single hole in the center of the Aluminum bar so I could use a screw to attach the smiths clamp.

I then drilled holes on the reverse side of the aluminum, a bigger hole in the center so I can fit the head of the allen screw, and two holes on each end so I could attach feet to keep it stable.

This is the Smith's clamp I used.

Here you can see the hole that was already in the bottom of the clamp that I used to attach the clamp to the aluminum Bar.

I had other plans for the red thumb screws that came with the clamp so I just replaced them with standard allen head screws.

Here is what the clamp looks like attached to the aluminum bar.

I then proceeded to make the feet to keep this thing stable, here is the piece of aluminum I used followed by pictures of it cut in half, holes I drilled, threaded, and feet attached.

Here it is with the feet attached. Starting to look like something now.

I then got a big chunk of aluminum, cut it in half and milled a 1" squares so they will slide on the aluminum bar. The thinner slots are for attaching the arms that the diamond plates will ride on.

I then drilled and tapped them to accept those red thumb screws. I used a universal joint socket with a 6" socket extension. They are permanently bonded together with steel putty so there is no play. They are perfectly straight and have no wiggle side to side or up and down.

I used a 3/4" aluminum bar to make the holders for the diamond plates. I used a square collet in the lathe and drilled a hole to accept the socket extensions. The diamond plates are DMT brand and are just epoxied onto the aluminum.

And here we are all done. It works good.




Conclusion:



This sharpener works very well, and was definitely cheaper than buying the Wicked Edge. I did however have to put a lot of man hours into this and it was still expensive buying all of the diamond plates from DMT. Just for two sets of diamond plates and the diamond paste it was roughly 140 dollars. If you add that into the labor I put into this, I think I would have been better off just buying the real thing. If i had to buy all of the aluminum I used for this project I probably would have ended up around 200 dollars total invested. It really opened my eyes as to why the Wicked Edge cost so much money. It takes a lot of time, and the materials that go into it are not cheap. The clamp on mine is no where near as strong as the one on the Wicked Edge, plus with the Wicked Edge you have keys to keep the spine of your blade in the same spot each time you sharpen it. I have to use a sharpy every time I sharpen and adjust where I slide the base of the arms so I am hitting the right spot on the edge. I am happy with the outcome of my Sharpening system, it gets the job done and I am able to obtain mirror finish blazing sharp edges every time. The biggest thing I took away from this project is new respect for the Wicked Edge. I used to think it was over priced for what you got, I now understand where the cost comes from, and think it is worth the investment. Thanks for taking the time to read this, please let me know what you guys think.

Very well done!

Honestly I like the way your arms attach to the base better than the original design. However, I noticed the socket extensions you used are knurled. How well do the bases for the diamond plates slide along that? Also, how big is the annular space between the hole in the sliding bases and the socket extensions (i.e. how tight is the fit)? I know with the W.E. some people slip a plastic straw over the guide rods to take up the clearance, in order to eliminate a small amount of play.

That's definetly a lot of work, and not a trivial materials cost either. Think of what you'd have to charge if you made that commercially (excluding lawyer fees from IP suits brought by Wicked Edge!). Definetly a reality check for when you start thinking these sharpening gizmos are overpriced.

Haha I will definitely NOT be selling these. One was enough. The universal socket joint is a very tight fit into the sliding base. I had to lightly tap it in. I went ahead and drilled and pinned it into position just to be safe. The diamond plate holders have a hole in them only .002 bigger than the socket extensions so there is no play there either. The hard part was making sure I have both of the sliding bases exactly the same. The knurled part of the extension is the exact same size as the rest and it does not cause any hang up issues at all. If anything it helps hold lubricant to keep things sliding like buttah.

That's pretty cool. I think I've seen one or two others that people have thrown together in their machine shops.

I'd like to see some manufacturer take one of those industrial factory robot arms and program it to sharpen a knife in a vise. It would be a big hit at a trade show.

Now that sounds like a great idea. If anyone wants to buy the robotic arm ill program it :D
 
Very nice job on the system............should work as good as the WE version.
I could never work metal good enough to duplicate what you've done.
If I were sharpening professionally I would choose a Wicked Edge type system.
I have a Edge Pro that I like a lot.
You can get very good edges on a Edge Pro.........with some practice.
Sharpening Knives is more or less a science.
There are people who have the skill to hand sharpen, that is a skill I have yet to master.
Again nice work.

Thank you for the kind words, but the machining is very basic and I'm sure anyone could do what I've done here if they tried. I agree sharpening is a science, you really have to understand what your doing in order to be successful. I've never been able to hold perfect bevels when free hand sharpening so that's why I decided to make this. I've been practicing sharpening a lot on my belt sander lately and I love how fast it is. The belt sander has been getting more use than my wicked edge clone lately just due to the time saving. I just use a 600 grit belt followed by a 9um belt and finish with a leather belt loaded with chromium oxide. Results are almost as good as spending the time using my clone.
 
That is an awesome sharpener. What is really cool to me is to see something home-brewed like that. I know if I made it and it was something I got a lot of use out of I would be pretty proud of myself every time I used it. It makes the experience that much better. Thank you for sharing.

On a side note, I did some home brewing like that today. I have an Edge Pro and made up my own balsa strops for it (4 total, I have a 5th blank I made that I am going to use with leather I think). It is no where near the handy work you did, but home brewed none-the-less!

Keep it up.
 
Thanks fellas, it was fun putting it together and works great. I always enjoy home made tinkering projects whether its my own or someone elses, its amazing to see what people come up with when they want/need something.
 
I know this is an old post but I'm interested in the pictures and the links are broken now. Any way someone can repost the pics? Or versions of their own?
 
Mike, I bought this from bpiatt a couple of years ago and is still in use. If you email or message me your contact information I will be happy to send some photos of it to you.
