TechStudio K01 Profile Sharpening System

Got an email from Paul last week, my grinderman stones are on the way!

Overall great system and I'm happy with my purchase.
 
A question to those who have received either K-01 or K-02 and tried. I saw several videos posted on YouTube. And it all looked the clamp wobbled up and down slightly whenever touched by grinding stones. Is that what is happening when you are sharpening yours?

Good question. I noticed the same thing. This system has me quite intrigued. That roller-bearing detent thingy is a thing of beauty.

Yes. For the same reason the clamp arms can adjust between full flat grind and saber grind causes the arms to buckle very slightly when using pressure. If not using much pressure, there won't be much movement. But yes, it does need to be accounted for and can be a little frustrating at higher grits. Still beats having an edge pro for full flat grinds and a wicked edge for saber.
 
Thanks for the reply, bodog. It seemed quite odd that there was some wiggle because everything looked like built around beefy steel with minimal tolerance. And the video posters didn't seem to bearing down on it with force. So, I can't quite figure out where can be the weak link. I'm thinking ordering the reinforced spring and swap it with the once came with. Would that fix the issure?

Don't know which spring would need to be reinforced. The only thing I could see needing to be reinforced are the clamp arms, but doing that would keep the system from being so effective on FFG and sabre ground blades. And whether they actually need reinforcement is debatable. It would just cut down on the time spent trying to hit the apex at higher grits.
 
It appears that the configurator on tsporf now has an option for upgraded springs that appear to address this problem.
 
I'm ordering the system with the upgraded spring hoping that it fixes any possible slack. Paul of Tech Studio has been great. It seems that he gave a lot of thoughts to designing and building the sharpener and knows every small details about his product. I'll post a review once I get my hands on it. Now, waiting game begins.

It has been selling in Russia for 5 years or so now I think. There is at least 1 mega thread on the Russian forums (linked in this post) where he listens and posts. Upgrades have continued as people make suggestions.
 
The clamp wobbling mentioned affects sharpening angle insignificantly. But still, the newest generations of the clamps has shorter springs (the design is changed, the shorter springs is not an option) and now the reinforced springs are available (as an option).
The reinforced springs is for thicker blades and for more stability on hard grits. It's less suitable for Full Flat Grind as the thicker springs bends worse and the jaws worse shape to a blade profile. The improved springs not replaces regular ones, it comes additionally.

As for lost parcels, very sorry for improper work of shipping companies. It's rare incidents but it happens unfortunately, in this cases we both, seller and customer, contact our local post representatives requesting to find the parcel. If the post cant find the lost parcel and all searching terms are passed we send an order repeatedly at our expense. All who ordered the sharpener receive it anyway, we highly appreciate every customer.

Currently we have diamond stones and silicon carbide stones made in Russia, silicon carbide stones made in the US. All the stones doing great as for feedback we have. If you feel something wrong with the stones please let me know your advice on which stones is better. Now we are getting Arkansas stones to extend an assortment.

The newest batch is coming to shipment, we are going to finish before 15 of December, please be a little patient.
 
The problem with clamping systems, (and not exclusive to tsprof's sharpener) is it's difficult to accommodate the wide variety of knife: shapes, styles, size, thickness, etc. so either more accessories are made, or just to learn to adapt some knives to the sharpener... which, for some people, this is a tough thing to do... but in reality, often is not that big a deal, and seldom affects the knife in actual use. So, for example, you may have to go up a degree or two to clear the clamp on a small knife.

Consistency is also more important that accuracy. So, if the clamp "wobbles", (which I assume means that it gives a bit when the stone touches the knife), it's not necessarily a big deal, if it, for example, drops a bit and then stays in place.

It's also good, (and one I would consider if I were buying this sharpener), that a "blade table" is offered... this is probably the best accessory to accommodate a variety of knives, or a knife that doesn't meet the "clamp" parameters.

The tsprof has a table you can use instead of clamps.
 
The new and "improved" K02 table attachment. Clamps things over 7mm thick. I personally preferred the previous models clamps that appeared to lock into place so you could use it like an Edge Pro. These ones don't even clamp flat down, the screws are too long.



With the screws tightened all the way


Apprentice marks galore
 
That seems strange that it wouldn't tighten all the way from 0-7+mm for versatility.

I wonder if you added some flat washers if that would close the gap for thinner blades. Seems like it could be a cheap and easy mod.

You could but then the screw would stick way out the top and you would only be able to sharpen at higher angles. To keep things lower it would be better to just buy some shorter screws.
