Ive been looking at sharpeners.
I like the tech studio because by spinning knife around the other side of blade can be sharpened.
Whether by spinning the knife around causes the blade or angle to change to effect sharpness outcome I haven’t heard or read about it.
There’s other fixed angle sharpeners that may be plenty for what I’m needing,but so far the tech studio looks more high quality than the others.
Anyone using one,if so does it do everything you want?

I did another search and it turns out there’s a section here on the forum,
https://www.bladeforums.com/threads/techstudio-k01-profile-sharpening-system.1401879/.
I’ll take a look at section but if you’ve used one or know someone that has,please post.
 
Edit: personal rating - 9/10, extremely competitive product

I have one and I love it, but it has a huge caveat for me.

First of all, the arm moves ever so slightly, burly built as that machine may be. This changes the angle as you use more pressure making apexing difficult sometimes. I manufactured an infinitely adjustable jamb that prevents any movement in the arm, so it is possible to fix that issue.

My machine will place a 15 degree angle on one side and a 15.2 degree angle on the other, so it is precise, but not absolutely perfect.

The necessity for constant angle cube use makes apexing at extreme grits a bit of a pain—my cube is accurate to +/- 0.05 degrees, but that still failed to be accurate enough to apex the bevel whilst also avoiding multiple-bevel-syndrome, if you will. So you will not find the K02 to be the optimal rig for creating utterly perfect mirrored bevels; bump uo your budget a few hundred and get a Wicked Edge if that is a high priority for you.

Here is what the system is incredible at: I set bevels on it at 14 degrees per side and take them up to the 400 grit EP stones, or 1000 on the Shapton Glass stones, then I’ll bump up the angle to 15 degrees and slap an 8k micro bevel on. Then you can maintain the microbevel super easily.

So in short:
Strengths: set your bevel, then use microbevels in order to circumnavigate a few issues that make the system a little cumbersome.

Weaknesses: making extremely high grit edges with perfectly crisp bevels—there is a minute amount of slop in the system that robs you of this.

Overall: In my opinion, it dominates the Edge Pro which I happily gave to my friend after receiving this system. It will effortlessly put perfect bevels on your blades up to 5k in my experience, which is plenty high enough for me. You can take it higher, but the amount of fidgeting you’ll have to do increases massively at a certain point. Therefore, I suggest microbevels. This system makes sharpening virtually effortless and enjoyable and highly varied, thanks to Gritomatic, and also allows the easy sharpening of a MASSIVE range of knives.

I really like my K02 and I wouldn't trade for anything,buy a K02 not a K01 if that's what your planning on I think you will like better.

Seconded. Get the K02–well, I think it’s actually the K03 now, but yeah, K02 or bust. That rolling detent flipping mechanism is amazing.

Also, OP, get a coarse diamond stone for reprofiling. Venev produces a good cheap one. The SiC stones aren’t bad, but the Atoma 140 I use brings the absolute HEAT.

Wade, what stone setup do you use? How high to you take your edges?
 
If you want really good stones that are going to last a very long time look into the Metallic Bonded CBN sold at Gritomatic they cut faster then any Diamond plate and even the Venev stones they also cut threw S110v like it's nothing,they are under the Poltava section on Gritomatic's site and you do not get the same tear out problem you do with diamond plates,I'm going to try and do a video this weekend of me using the Metallic Bonded CBN's.

I have not had anything but joy and exceptional results from my k02. I have not had the problem of bevel changes like mentioned above. I did calibrate my unit and all of its clamps. I also make sure to adjust for different stone thicknesses. I have zero regrets other than I did not get the K03 unit, but that is a very small difference in the end. I have gotten nearly every accessory available for the k02, plus a pile of different types of stones. It is very well made and does a superb job. The wicked edge is nice for sure, but I do not think it is as adaptable as the k02 with all of its accessories available. It is very versatile.
I just got a set of the metalic cbn stones from gritomatic and I am very impressed so far. I still need to get more time in with them before I say for sure if they are worth the price, but so far they are showing to have a lot of potential.
 
So far it sounds very good even with its margin of error.
With 15.00 degrees on one side,15.2 on the other that’s not bad at all.
I think that’s just an error of 0.5% on each angle which will be fine for my EDC knives.
I’ll watch a few more videos and I didn’t know there was a KO3 so I’ll look at website again.

And that margin of error only exists if you don’t use your angle cube when you flip the knife. You can recorrect it to 15 every time you flip the knife. I found that to take too much time so I just lived with the angle being slightly off and It was completely imperceptible to the naked eye anyway, yeah, it’s not a big deal. And if you get stones of equivalent thickness, you could actually just measure once to start and take your edge up to at least 2000 JIS with out any fidgeting at all. Just measure once and go hard. I imagine some of the Venev and Poltava stones will be fast/abrasive enough to take the edge considerably higher without the need for more measuring, as they may have the capability to sharpen right through the system’s miniscule margin of error
