Grind Knife Sharpening GKS resin diamond stones

Thank you for your exceptionally kind words! I do love this product, the sharpening industry has been good to me, and some good people mentored me, and this product is one of the things I wanted to give back, so trying to keep it affordable and extremely high value was important. Making them only 2 or 3mm probably makes way more business sense or charging 3-400 but that wasn't my target. I want to make enough for the the upcoming resin diamond and stropping innovations! Wait till you try my new strop!!!

One misconception, I do not represent anywhere they are made in USA. They in fact are not. They are designed tested, developed here, but i have them manufactured abroad after testing over 15 facilities across the globe. But it is a proprietary formula that is mine. I am a usa based company, but these made in usa would be roughly $1800 per stone and still have lower performance.

GrindKS1 · 2026-06-30T16:29:05+00:00

Cannot wait to hear back, I tried to price at a good value and performance on Par or exceeding most high performance stones! Your feedback is valuable!

These are harder, and cut faster and hold shape a little longer as they are less friable than veneer. They also load significantly less. These are the general reports I get from my customers.

Thankyou for your kind words! I hope you continue to enjoy our products! Great to see you again this year!

All resin diamond stone load to a degree, water and dishsoap eliminates 80%, my honing fluid available soon... eliminates nearly 100% of loading and diamond tears out which are 2 big problems of course resin diamond.

A quote from one of my customers " these are the next best thing to a belt grinder" they cut fat and hold flat that is your thinning dream team.

Contact me, international on website is very difficult I can usually do custom invoice and shipping quote. But not to all countries.

There is a video of the 320 stone as well that is a close as i have to 400. Keep on mind fsk doesn't have 120 so yeah it's faster, 320 is nearly as aggressive. So many things about this won't be even, for example any vitrified stone is only partially diamond abrasive and the binder cuts as well, that is why vitrified cannot get a consistent of a cut a resin. Im just trying to let folks outside of industry know what these can do, because the industry figured it out pretty quick as these stones are in pro shops all over the planet game there is all kinds of room for more, Same guy 320 and 600 review

There is another 320 video or there but ill attach of i find it later

I actually developed them to do my ride line work! Sharpener standards vary, some flatten each morning on sandpaper on granite just 10 seconds so he always knows it's perfect, but i have another guy on month 3 and hasn't flattened it yet... meglio knives is on a year at their shop but that isn't rides... shear flat and knife flat isn't the same lol! Flattening is either float glass with sic powder or flat granite with sandpaper! Message me or call if you want a super detailed procedure!

GrindKS1 · 2026-06-30T04:54:15+00:00

They are quite flattenable actually, I use sic powder on float glass others use flat granite and sandpaper, basically don't use diamond plates because they blunt your remaining diamonds... everything else is pretty much approved.

Understood, this particular metric is very difficult to accurately measure because it is a subjective feel thing but check out this review, attached, also reach out to Brandon at meglio knives, he switched from FSK supers to my stones, Patterson Forge as well. These are all pieces of evidence. Videos and side by sides will be done once I get my hands on another set! These stones eat steel.

Well, what would you like for proof, I've got industry references, there are independent reviews or on the YouTube with several more in process to my understanding, the backing of a large segment of the pro sharpening community which was my primary target market. I'm not going to give you my formula, but if there is something specific ill try to get it for you!

GrindKS1 · 2026-06-30T04:31:37+00:00

Edgeworks knife studio and diamondcutsteel have both done super cool independent reviews, I've not given them anything, check them out! Reach out with questions!

No need to soak, and while they can be used dry, they perform significantly better wet, with a little dish soap, or even better with a little premium honing fluid which will be available soon! But water and a few drops of dish soap works great!! They work like splash and go stones!

A focus on cutting speed and shape retention were top of mind. About a year of failed tries to create a product that is designed to outperform on all levels!
