THE REAL DEAL DIAMOND PASTE!
After months of trying to find a true working diamond paste, I finally decided to try TechDiamondTools. The pricing was great and quite frankly the cheap diamond paste was just not working for me (yeah...i tried to go cheap). I've been trying to find a reliable way to get scratches out of mineral glass and most internet searches claimed it was very difficult. Not only could I not find a guide to do this, but couldn't find a grit guide to use for mineral glass. The first thing I did was message the TechDiamondTools and asked for guidance. They replied to me several times and have been very courteous and helpful. They recommended several grits to try, so I went ahead and ordered.Here is what I used, and it works GREAT! Just be patient (this is the key to perfection).Rotary Tool (Cheap) I also used an adjustable speed control rotary tool with 3/32 pro bits compatible that is used for nail manicures. It's electric. I did a search on Amazon and the no longer sell it, but Pinkiou looks similar and it's cheap. I don't recommend using a high speed Dremel. I have one and it goes way to fast.I started with 600, then 1,500, 3,000, and finally 5,000 grit. The results were amazing!Now to keep things in perspective, I did mess up and used sandpaper on one of my other watches. Used 100 grit and that was a mistake. The pictures I posted, I didn't use sandpaper. On the other watch, it did get all the scratches the sandpaper made, however it took a bit more of time. Next time I'm using 2,000/1,500 grit sandpaper. I've read that's what should be used before using diamond paste. I currently have a 14,000 grit that I can't decide whether to use for polishing since the 5,000 did a superb job. I may just return that 14,000 and use the 8,000 for final polishing.Okay, back to the watch. the pictures are the result so the diamond paste. I "wish" that I had a picture of the watch before I even started, but I totally forgot to take some. The pictures are after I had already gone through using the 600 grit and the 1500 grit. As you can see the scratches I circled. Trust me before I started, these scratches were pretty bad. You could actually catch you fingernail on it. Not just a hairline scratch either. The final picture is the finished product, although it looks superb and flawless, I wonder what a final polish with 8,000 or 14,000 would do. I haven't tried that yet. Anyway, I am very pleased with DiamondTechTools, they actually worked with me to replace the 400 grit because it seemed watered down, but they made it right. As a hobby I work on Casio's digital watches and refurbish them, and the biggest problem with refurbishing is the scratches on the glass.Well to end this, I'd like to say I did order the 400 grit paste and will start with that to see if it cuts back on my time. The pictures of the watch I posted took me about 3 hours to get the scratches out, I'm hoping with 400 grit, I'm able to cut that time in half. I don't like to used sand paper, but I will if there are a lot of bad scratches, then I will. Just don't use 100 grit like I did. Use 2,000 or 1,500. I'd also like to say, if you use this process, your result may vary. I want to say that because I'm a very meticulous person and I take my time. I'm only putting this out because this actually worked for me after all failed attempts with other diamond paste, and no I didn't get any free products from TechDiamondTools. If Amazon lets me, since I ordered like 6 syringes of different grits, I want to post more pictures of scratched up watches and the results. Hope this helps folks out there that have not found any documents on getting scratches out of mineral glass, because there really isn't any clear document that outline this.Hope this help those watch enthusiast out there!! And thank you DiamondTechTools, ya'll are awesome and keep making those American Products GREAT!!!

Use this on a leather strop for honing carving knives
This is an excellent diamond honing paste which i use for finishing knife edges on a strop. Works VERY well and gives a very nice polish (and smooth cutting feel) on my carving knives. The paste also seems to last quite long on the strop, highly recommend this product.

This stuff is highly effective for creating a scary sharp edge to finish out your knives on a strop. Quality item. Will buy again for sure!

good compound for knife sharpening leather strop
This stuff seems to work quite well on my leather strop. It takes a very small amount so I suppose this very small tube should last a reasonable period for my use. I am not an expert sharpener but trying to up my game with a decent diamond plate "stone" and a good strop to hone fully remove the burr. Not trying to get too precious with lots of fine step gradations, doing just two stones and one stropping step. Was hesitant not knowing which grit of compound to get. I settled on this "2,000 grit, 4-8 micron" tube. I'm pleased with the results, though I have not tried other grits so have little to compare it to. It is much finer than the final step of the diamond sharpening stone I'm using, the Sharpal 162N. So the progression is 325 to 1200 (stones) to 2000 strop which makes sense to me anyway.

No results
The media could not be loaded. Trying to polish glass. Diamond should cut glass no problem. But I am not receiving any good results. Trying more and more and I will let you know if I get any better results. I cannot tell you how much diamond there is in this paste. I even softened it in the microwave as instructed. See my video

It works for most surfaces, but beware with glass
This definitely works as advertised to take out deep and excessive scrapes and cuts on glass, but will still leave a very subtle scratch pattern like you see on some older cars that have been through car washes a lot if that makes visual sense. I would recommend it for most situations, but beware that if you want it to look like brand new glass, you may need to either replace the glass or find a different type of product. I decided to keep it because it is definitely useful and can get the worst scratches buffed out pretty nicely.

I used to shine metal knive, put the finishing touch on the sharpening knive.

This 50% diamond grit polishing paste is excellent…
The fact that this is 50% diamond grit, means that you use less, and get the job done quicker, which means that this is a brilliant product, which is likely to work out cheaper in the long run, especially if you are comparing it to the products that are only 5% to 10% diamond grit. And, I would’ve shown you how much it works with an opal that I spent just twenty minutes polishing, but I was unable to upload the pictures and video, because I refused to allow amazon access to my whole collection of pictures and videos.

Excellent paste, very fine
This paste (14,000 grit) does wonder to my straight edge razor after the 10,000 grit stone (using flat leather strop).I might still get the 50,000 grit to get a perfect edge, but it's already close to being "as new".

Outstanding
