so, what do you think?

Takes the fun out of it. I guess for someone who doesn't enjoy sharpening, or perhaps a knifemakers who is most concerned with time & money. But I really don't see it being a hit with most knife enthusiasts. And I wonder how much $$$ it will end up in the end.
 
Water bottle and rope chopping isn't something I do. Take a $400 Japanese gyuto, take some edge photos using a microscope before/after and let an expert sushi chef see how he or she likes the edge afterwards.

Next, take an intentionally dulled Case Peanut, run it through, see if you can shave arm-hair with it when done.

Repeat the process for a 4" blade modern folder with a high vanadium steel. Paper and shaving tests before/after.

Run a typical knife through it 10 times, and do a before-after comparison of how much blade stock was removed.

Test it on everything from a 3" paring knife to a 10" chef.

Try it on a wharncliffe, as well as a skinner. Try it on a blade with recurve. What does the tip look like afterwards?

If it can deal with all of those things, then it's probably a great tool and the age of hand sharpening will end.
 
I was going to dismiss the premise till I saw the Ed Shempp endorsement.
Still sceptical, but made it a little more interesting.
 
Sharpening made harder than it needs to be...

Everyone thinks sharpening is some difficult task but in truth it's just the lack of knowledge that holds everyone back. Knowledge that is continually lost by these needless inventions.
 
Knowledge as well as patience and the right tools. Many don't even have one, much less all 3.
 
I enjoy sharpening. I do several hundred a year for people. I'm sure it will be big $$$. No robot necessary.

That's quotable just sayin ;)


Anyway yes I agree not for the everyday man but let's say in your situation if you had say ten of those that's ten knives every five minutes. If you had it running 12 hours that's 1440 knives...... of course the belt changes and all would change it but...... if it gave a great edge then I'd say for some people maybe yes for me? Hell no! I'll stick to my trusty norton!
 
My lack of patience is the main thing holding me back. I also lack the knowledge, but I know I don't have the patience to take the time to really learn.

Smaller belts means they wear out faster. When I used a 2x72 a 120 grit Norton Blaze would do about 100 knives, my 1x42 cuts that down to about 30-40 knives. So an even smaller belt would mean less knives sharpened before belt changes which would increase overall sharpening cost on the professional level.

I can also sharpen a little over 1 knife per minute on my 1x42 making this device seem rather slow for just a belt sharpening. I also see it having lots of trouble with damaged edges or rounded tips.
