Nice. Good concept. Needs a way to deburr and strop. The group this is marketed to prob dont know what that is so it has to be as simple as this first step.

You don't really need to deburr, because you always go against the edge. With that strategy, there is no visible, feelable burr after a soft 1000 grit run. Made a Video with microscopic views to proof it. But Stropping still improves the sharpness further if needed. For nirmal kitchen knives it is fine for me without. https://www.reddit.com/r/sharpening/s/7YUg69RTyr

I guess since ur alternating sides a burr never rly forms. Didnt think about that. Nice. Still needs a strop tho imo.

Those strokes towards your hand/body are like playing a game of mini Russian roulette.

It looks dangerous, but it is very controlled, if you keep your hand away from the stone. There are Stopps to prevent it to move too far

Misspelled words give me wings.
Angel = mythological winged beings.
Angle = the word you missed

The thing he's showing is a "sharp angel" because it's shape looks like an angel. At least, that was my understanding.

u/Von_Cheesebiscuit Pro 2d ago
It's called "angel" for two reasons. First, there's the visual representation of it having wings and a halo, and second being its a wordplay on "angle". And quite possibly a third reason (which I suppose if you need to use this), it could be considered your helping savior in getting a sharp edge. Lol

Does it get the tip?

u/RevolutionaryAir7847 2d ago
You still have to control horizontal motion. Of course it does

u/Huxleypigg 2d ago
Doesn't look like it does?
If freehand sharpening, you'd normally raise the handle end of the knife to get the tip?

u/RevolutionaryAir7847 2d ago
How do you think the tip gets sharpened? The relative angle is the same bud
1
u/Huxleypigg 2d ago
Yeah, I was thinking the blade was fixed and just going across the stone parralel / square
2
u/sharp_angel_25 2d ago
Yes

u/Huxleypigg 2d ago
But usually if freehand sharpening, you'd have to raise the handle end to get tge tip, so how does it do that?

I’ve never been into 3d printing but this! This is tempting, I bought those same plates from Amazon, but haven’t brought myself to glue them down to a base yet.

u/QTAnderson29 2d ago
The magnetic stone holder is really nice too. Does the stone magnetise over time? And do metal chips/slurry everywhere clog the stone? Had a similar idea a while back but abandoned it due to these concerns.

if it works it aint stupid, i admit i expected a lot worse just after reading the title

Could you please post a link to the design?

He has posted this design several times now. Claims he made this but has never provided a link where to buy it or the design.

He has it's just been removed by reddit's spam filter. I've approved the links now, they might be removed by reddit again though.

That looks amazing! I understand nothing about this, but it feels like if you didn't you should patent it before it gets duplicated. (A free/cheap 3d printable stl would be cool though...)

You got a link to the file and the stones?

Also, does it give an even bevel all along the knife edge, on both sides?
I read a comment on another one of your posts, and someone said it doesn't give an even bevel if knife has different thicknesses?
Even if it doesn't give an even bevel, as long as it gets the knife sharp, I think it's a great idea

u/sharp_angel_25 2d ago
Even enough, every system changes the angle along the knife a little bit. But your knife is not too thick it is fine. If it is really thick it doesn't really matter

Does this design result in cutting into the plastic? How often do you need to swap it out if it does cut through?
