Check out this wack robotic knife sharpener!

since paper wheels DO overheat blades, I wonder if there's a way to tell if a blade lost its temper after a trip thru the ReSharp?

The blade wasn't hot when it came out, or discolored.
 
What will be next: buying pizzas from a vending machine?
Oh... that's right...
 
I had NO IDEA that was possible!!😳
the breadth and depth of knowledge on BF continues to amaze me . . .
*Here is an in-use example of thermo-paint activation related to a paper-wheel sharpener application:
Three different temp-paints applied (325°f / 450°F / 700°F), paper sharpening wheel applied to opposite side bevel.
1) Paint as applied.
2) Post paperwheel 450°F paint fully activated.
3) Post paperwheel no paint activated.

*Alternate Blade: (325°F Lacquer just activated)

I have a tub full of flea market knives most of which cost $1 or less. They are candidates for the ReSharp. Can someone do a BESS test on a ReSharp victim?
 
I would only stick a cheap Walmart special in there (kitchen). Think I would be better off using a bastard file to it. Works good on my Broadhead's.

is this machine designed and engineered in the US or CN
I do not have those answers, but below is a little bit-o history info.
Note:
1) The CA-xxx patent number is Canadian, but I believe it refers back to U.S. & The Hillman Group, Sharp Systems, Inc.
2) The AU-xxx patent number is Austrailian, refers back to U.S. & The Hillman Group (name change as of 4/30/2020) previously Sharp Systems, Inc.
3) The EP-xxx patenet Number(s) are European,
It appears the company has changes names a couple times.

Personally would not use this type of a machine based on the results I have seen. It appears they have saturated a number of U.S. market areas.

Current company name/location:

Two additional documents to the above table I was not able to see/review.
 
In the absence of hard data regarding the ReSharp service at Ace Hardware, I dragged my BESS Tester and a couple of knives over to my local Ace. The computerized sharpening machine is kept behind the service counter. The first knife, a 10” Forschner, started at 386 BESS. After 1 trip through the machine, it measured 149. See the Bess table below. The second knife, a smaller Japanese? Titanium model, started at 874 BESS. After 1 trip through the gizmo, it measured 367. The secret ingredient, Titanium Carbide, is harder than Vanadium Carbide. After a second trip, it measured 264. The technician was happy to get the feed back. 264 is new knife territory. 149 is razor blade territory.
The cost is $6.99/knife at my Ace. The blade can be between 2 1/2” and 12” long and between 1/2” and 3 1/2” tall. They can’t do serrated or scalloped edges. No recurved or single bevel blades and no ceramic knives. The computer examines the knife during the process and utilizes 3 different gritty belts and 1 stropping belt.

How do you you think a Cuda Maxx would do in one of these machines with the integrated handguard on the blade?? I have a Bowie that I bought recently and it came with some small chipping towards the tip

They don’t give you close access to the machine. If you bring the knife in, they should be able to advise you on possible guard interference and/or chip removal. The CUDA guard is way behind the base of the edge.

I think you got that backwards. Otherwise great information

The various sources on Carbide hardnesses don’t always agree with each other. I probably could have said that TiC and VC are both very hard. Most of my Titanium bladed knives get their wear resistance from the inclusion of Titanium Carbides. I am not aware of any Ti blades with VC inclusions.View attachment 2039168
