Toohr #3 knife sharpener

scottc3 said:
I am trying the Toohr 3 because of the slide, which I think adds functionality to clamped, tool free clamps, or magnetic tables with guides. From Bdtry's break out I see solid materials chosen, so I'm less concerned about all the added subsystems as additional points of failure and maintenance problems.

Cool, that's why I would try it too. But not for any more than it sells for currently. I already have a multi hundred dollar sharpening system that should sharpen nearly anything I need it to and doesn't need to be re worked out of the box (as it shouldn't at it's price point). The draw to this Toohr for me is the possibility of use for sword length blades, which it is not marketed as or gaurenteed able to do and that is the only thing I would need it for. If it doesn't work for swords, it can go in the trash and I will not spend a penny more than what they currently sell at to find out it was a waste of time and money.

I doubt even a fraction of their sales would have been possible if not for the dirt cheap pricing, and I think their sales will suffer terribly if they push the limits (which it is already at for a chinese clone of questionable quality). Additionally, raising prices because of popularity is bull squash; the more units made and sold means lower cost/unit to manufacture, not the other way around. So to make and sell more while increasing pricing and maintaining low quality is an insult and a pure money grab.
 
Can we stay updated on using these sharpeners.....
I'd love to see a variety of knives tested.
I'm in the market for Something, I think?
 
Well, a few people asked and I thought a few people might be interested in first thoughts and what not so scottc3 scottc3 Crag the Brewer Crag the Brewer cudgee cudgee 777 Edge 777 Edge L Lovetolearnabouteverythin

First off, when you reassemble the unit and put the top cap on the upright unit make sure the brass thumb screw is on the OUTSIDE 😅 For some odd reason the gimbal doesn't like to spin with something in the way 😂

And then I used one of the included stones to put a bevel on the abrasive rod to make putting it in the bearing and the stop collar on a tiny bit easier. You never know if the sharp corner might catch a bearing ball and damage something. Probably not necessary buuuut better safe than sorry.

I know the included stones are bad, but I was surprised at just how soft they are. They were always intended for utility use instead of sharpening anyways. Putting the bevel on the rod left a large channel in the stone.

First knife was an 8" Zwilling twin master chef knife. Set to 20° the gimbal is not quite half way to the top. It sharpened perfectly fine. Clamps worked well.

I noticed that the LM8UU bearing for the abrasive holder rod was incredibly smooth when running it while holding it up, but when you put any pressure down on the knife you would sometimes feel a bumpiness from the bearing. Not sure if there is just a couple spaces in the bearings that I hit at those points or what but I figured I would mention it. There were no hangups but you could feel the bumps.

Next up was a much smaller steak knife. And here is where I ran into some problems with the clamps. The angle was set to 20° and the stone actually hit the side of the clamp on the narrower end of the blade. it seems that at least at 20° you need 9mm or so at the bare minimum of blade sticking out from the clamp or you will start grinding them. This amount will increase if you want a shallower angle and decrease for a steeper angle. The second picture was after I repositioned the blade and made sure it cleared.

After that I sharpened a couple more of those steak knives and that was it for the day. I had some smaller utility knives that were too small to be sharpened. I will have to see how they perform with the Haptsone clamps I ordered. If not I will have to stick with my Tsprof Blitz Pro to sharpen my smaller knives.

roller bearings?

I'm confident that you'll have success at a lower angle with the R2 Lite clamps you ordered. :)
 
Here are some pics I just took to see if we push the limits...

This is a small Victorinox blade with the sharpening angle set to 16 degrees (or 15.99 degrees on the Axicube-One :)

You can see that the stone still clears the Hapstone R2 Lite clamps at this angle. And that is with a tiny blade.

Wow, I am assuming I can’t get a 8 degree angle with my petty 150mm knife with a blade height of 29.64mm?

I just checked a similar knife profile for you on the R2 Lite clamps with a kitchen knife that I forged a couple years ago. With a blade height of 28mm, clamped 5.5mm deep into the Hapstone R2 Lite clamps and 22.5mm protruding beyond the clamp I can get down to 10.7 degrees with the rear section of the clamp being the limit. The blade spine is 3mm thick and its ful flat ground.

As a matter of interest, using the TooHR clamps with the same knife, I can get down as low as 11.4 degrees before the front section of the TooHR becomes the limit. The knife was not as secure as with the R2 clamps though. The only reason why it is close to the same limit as the R2 clamps, is because it is not a blade with a very low height. For a smaller knife, the TooHR clamps are much more limiting.

Using my Leading Edge magnetic platform on the TooHR, I can get the sharpening angle down as low as the knife grind geometry can handle, in this case about 6 degrees. :cool:

To be fair, 8 degrees is incredibly low and you will be hard pressed to find a clamp sharpener that can do it simply due to the geometry of the clamp bar and clamps. You would need a table type setup as 777 Edge 777 Edge mentioned. What steel is your knife made from that it would support such an angle?
 
Lovetolearnabouteverythin said:
Cool! Where can I buy that?

As a matter of interest, you can also use any other TSProf K03 or TSProf Kadet clamps on the TooHR system. You can also use any Hapstone R2 series clamp in your TooHR, but for a Hapstone clamp you'll need the adapter mentioned above in post #31 of this thread.

With some of the longer TSProf clamps / fillet clamps or longer Hapstone clamps, you can get very low angles.

It’s a R2 Japanese knife, the maker is known for putting 8 to 9 degree micro bevel on chef knife.

You are buying an item made in China that costs $70-$100 USD. Imperfections are to be expected, if parts are damaged you will have to message the seller. If you had the sliding base unit made in the USA it alone will cost more than this entire sharpener, likely by several times but it will be clean and without blemishes. If you want a version of this sharpener that will come perfect out of the box that you won't have to mess with, blemish free, with a warranty and support then this is what you want, with the price to match https://schleifjunkies.de/en/product/grindjunkies-grinder/

Yes, and the current pricing is the only thing making this system somewhat acceptable given those factors. Any more, and that is unacceptable, regardless of "popularity". Again, the more units they make, the less the per unit manufacturing cost becomes; in other words, making more to meet the demand of "popularity" while upping pricing is a greed fueled juicing of the customer, plain and simple and is insulting. I do believe these are cast parts that have been machined only where mated with other parts, rather then being fully machined from stock. They could increase quality (machined parts v.s. cast, certified quality and specified aluminum alloy, proper fitting parts, perfect functionality out of the box etc.), offer warranty and excellent support, and then up the price justifiably..but at that point why not just buy the real thing (SJ that this was cloned from)? Also, the clamps even without adapters cost as much if not more than the system itself.

I think this system looks good for the current cost but..bottom line is that this is a Chinese, mass produced, bootleg clone with corners cut. There is no way this system can command anywhere near the pricing of the SJ, and trying to do so would be suicide in regards to sales. This is a competition for money..price yourself out of the competition and consumers will spend their money elsewhere. Do you want some money, or no money??
