I decided I want to get some diamond paste, I have 0.5 chromium oxide already and wanted to try the diamond too see how it compares, so if it's not exactly the micron size listed I'm not too worried, but I don't really want to spend the full $22 for the spray so I've been looking around the internet for different options, I narrowed it down to a few I think would warrant consideration, mostly price if it turns out I don't like the feel of a diamond stropped edge it won't be too big of a deal but at the same time if it turns out to work fine I would like to figure out which is more economical a paste, a spray, or a powder.

TEMO 0.5 Micron 1 pc 5 gram syringes diamond compound polishing paste - Amazon.com

while only 5 grams it's the only supplier who has any feedback, even if none of it is about use for razors.
Amazon.com: Diamond Powder 50000 Grit 0-0.5microns -25cts.,= 5 Grams: Arts, Crafts & Sewing

Amazon.com: Diamond Powder #1/2 Micron (60,000 Grit) - 25 Ct Vial: Industrial & Scientific

while it doesn't have any feed back or reviews the shear amount of powder diamond is interesting, being twice the amount of what's in the SRD spray. so if this one if legit I would surely be set for a long time with this.

10 Gram W0 5 10000 Grit Diamond Polishing Lapping Paste Compound Oil Based | eBay

at 10grams its twice as big as the first paste and the brand does seem to have an established product in industrial diamond grind wheels and other abrasive products so it has a little more weight than some random non brand name paste out of china (most of these are from china anyways)

Diamond Compund Polishing Paste, 0.5 Micron, 10 gram - EQ-MW05

out off all of them I think this one has the most potential to be what it says it is, another member of the forum has a thread about buying this and said it worked well and seeing how it can be traced directly to a manufacturer who also makes other "research and engineer equipment" makes it look pretty legit, but also twice the price of the other stuff

so in conclusion I'm having trouble on which one I want to pick, so I wanted to see what others think.
