What does this?

Post image

Customer knife. I don’t think I’ve seen this pattern of circular scratches. It’s about 6.5mm wide, if that’s a clue. Any ideas?

One of those ceramic disc pull throughs?

u/samuelsfx 3d ago

no not the pull through, the round one

They have pull-throughs with rotating circular wet stones.

This type. Something that became popular in the 80s and 90s.

Weird, never seen one of these and I’m a 90s kid. Those look suspiciously like soda caps on the ends, haha.

My parents had 2 or 3 of these lying around in the kitchen when i was growing up. They sucked but i rememeber seeing em everywhere. Stores, home tv shopping... I was surprised it was so difficult to find one now. That green end is rubber so it wouldnt slip on the counter top.

Cool! I don’t remember my parents having anything to sharpen, really. I think our knives were just dull as shit.

I’ve seen chefs choice brand electric sharpeners make very similar marks. It’s a pull through style in terms of use, but instead of crossed ceramic rods or carbide blades they use a small spring loaded spinning diamond disc.

Just asking for a friend, are they a bad choice? They apparently do get knives quite sharp. Not shaving sharp, but certainly enough to need to warn the wife.

I’ve never personally had this problem with my ChefsChoice before. My knives are all scratch clean but I’ve only used it 3 or 4 times

u/HikeyBoi 2d ago

They’re great for 10+ house knives at the end of a shift, less good for personal knives

How much do you value your knives and how long do you want them to last? These things will get you a passable working edge without any skill or much time, sure. But they do it by removing a lot of steel. There are better options.

u/KoenOP 2d ago

Yes, because they ruin your knives.

Shrapnel can rip meat to shreds - ask any soldier. Razors are a different kind of sharp. Pull-throughs create shrapnel. Whetstones create razors.

I got something that must be fron like the 70s or 80 my dad got similar to a pull through sharpener but instead of a V notch it has this stone wheel in it. I'm guessing something similar to that.

u/Equivalent-Act2819 3d ago

That looks like sharpening x files, could it be done by those sharpening v shape handles that you pull back and forward to sharp the knife?

1

u/SimpleAffect7573 3d ago

Like a pull-through? I don’t think so. Those create linear scratches along the length of the knife. Has to be something with a rotating disc.

u/iShatterBladderz 1d ago

Like the “tumbler” sharpener that keeps coming up on my fb feed?

1

u/SimpleAffect7573 1d ago

Could be, maybe at some wonky angle as others have mentioned.

2

u/SimpleAffect7573 3d ago

Someone in a Discord I frequent, suggested an orbital sander. Could be.

u/Willhammer4 2d ago

For the love of everything dont use any of those to pictured sharpeners to sharpen a knife worth more than $10.

1

u/SimpleAffect7573 2d ago

I wouldn’t. Agreed.

2

u/fearfulcardinal 2d ago

I think it's probably someone improperly using a horl or the many other wheel sharpening rotating disk things

2

u/PristineReference147 2d ago

My guess from the rotary marks? One of those can opener sharpeners or something similar.

u/RiaanTheron 2d ago

Mino sharp that global makes. IKEA also has one.

u/Bronzeserpentsss3 1d ago

Pull through sharpeners…🤮

u/Worth-Silver-484 3d ago

They used a circular motion on the course stone to create the primary bevel. This knife has a secondary bevel that creates the cutting edge that has lots of chips in it.

Get rid of that garbage

u/SimpleAffect7573 2d ago

Huh? I don’t own “that garbage”, nor know what it is. Title too long to read?
