Chinese Bonded diamond sharpening stones

[electro-static]

So I’ve been seeing a bunch of Chinese made whetstones hit the market that claim to be either some type of bonded diamond, diamond in a SiC matrix, or vitrified diamond (usually around $80-100). I’ve bought a couple from a brand called “kintif” (400 and 1000 grit) and managed to get hair whittling edges on mamaxet. Has anyone else tried these?

Oooh, I was on a hunt for bonded diamond stones some months ago and back then there wasn't really any alternative to the Venevs, PDTs and Naniwas, especially when it came to cost.

I did get a Venev Centaur double sided 2"x8" stone which is pretty nice but quite soft and I didn't have a choice of grit, there was only 5/7+10/14 at an affordable enough price.

I'll give those a look. I also found cheefarcuut (god, who makes up those names? xD). Yet another rabbit hole to go down into :D

The cheefarcuut stones cut steel very aggressively, more so than veneve resin bonded, or the Kintif. The edge finish is rougher on the 1000, and the stone binding isn’t as good as the previous ones so it will scar and dish more often.

How can we be sure these materials are not adulterated with lead or other toxins?

Oh, yeah, I see the cheefars are only 400 and 1000. The kintifs are only single side though (the double sided cheefar looked interesting, apart from the grits).

Weird about the binding. Weren't they supposed to be vitrified diamond? I always thought that was basically everlasting

If the temp control during vitrification isn’t dialed in, binding of the diamond grains will be weaker. Think I saw a reddit thread where someone was trying to make their own, they were having issues with the binding as well said it was the heat control during the vitrification step.

This is interesting for a secondary reason.

According to a cryptozoologist and archaeologist I know, the ancients abandoned metallic tools as too weak after they reached the technology capacity to create industrial Vitrified Diamond and Elastic Stone materials.

He said they knew of all of our super metals like MagnaCut and VG10 and Inconel and Tool Steel but decided those are short lived and weak.
Grown Atomic controlled stone and Vitrified Mineral materials like Gems are stronger and longer lasting.

Some of his proofs are the ancient Vitrified Forts of Scotland and other places which were melted by plasma energy, the Radioactive Libyan Desert Glass, Stone Henge, Easter Island, pyramids etc.

Allegedly George Lucas and Steven Spielberg were asked by a materials engineer why do star faring cultures use super metal alloys when metal is weaker than diamond composites and ceramics?

Both men allegedly said

1 Warp Field and Hyperspace Fields require conductive metals to operate.

2 Space is full of metal asteroids.

3 Once you can control Subatomic forces like gravity you can compress metal to be stronger and harder than diamond ceramic and stone.

I see value in both views.

I plan to get a SharpMaker. I need to use my Diamond Plate TriFold sharpener.

Now I hope to see Vitrified Diamond Boron Nitride knives.
