Sharpening stones

[maaa242]

Hello.
I have sharpening system but most of my been stolen from me so I'm looking for new stones now. I don't want to spend hundreds of pounds again and I was looking for good replacement on aliexpress and eBay.
Anyone have any experience with stones on the photo ?

In most cases, your system is what defines how pleasurable the process of sharpening is. Chinese apex feels worse than real apex, but when both are given real apex stones they will produce similar results. If both will be given shitty stones, both will produce crappy results. Just my 0.02

Hi,
Ive no experience
but I see you're looking at the "oil" stones that run ~$40 currently,

I would suggest you consider the regular stones,
a 6 pack can be had for $7-$8 ( "6 Pcs Sharpening System Kitchen Knife Cutting Sharpener Stone Abrader Tools Kit")
or individually for up to $2 per stone
Or the diamond versions which on sale at $3.82 per piece ( "Kitchen knife Apex edge sharpener replacement diamond whetstone grinding stone" )


Here is a pretty good review of the stones, the pics are sometimes fuzzy, but the info is good, sharpens all kinds of steels s30v cpm153...
Edge Pro Clone-Three Step/Plateau on Guided System page 2 page 3

Either stones will work to get really sharp once you figure it out (head hair whittling),
some may need gluing back to backing
most non diamond stones need lapping eventually
all are servicable, dont need high grits to whittle hair, or every stone they sell

I was thinking about oil ones just because i thought they don't clog up so easily. I use to have cheap set of stones but to sharpen my knifes well was taking me ages.

Hi,
Thats good thinking,
but the cheaper alumox stones can use oil for lube as well,
but they both need lapping to recondition when they wear

That review i linked notes 200# Diamond cuts faster than the 180# stone. but notes the 2k/3k are more like 1.5k

Those oil stones are same price or higher price than the diamonds,
but I don't really see any advantage to them at 2000 grit and under

sure diamonds are usually coarser than same grit rating non-diamond but
and even a 2000 grit diamond finish (or 1.5k finish)
is only some
5-20 passes per side on a pasted strop (canvas/denim/leather/paper)
away from a comfortable face shave


My way of thinking, get the cheapest set of stones you like up to 3000 grit
so $6/$8/$20/$25... for 4-8 stones

If the set doesn't include one,
add an extra extra coarse stone like 80 grit diamond for ~$4 for regrinds
of a coarse like 200 grit diamond for ~$4 for faster initial low pressure sharpening

And for higher grits than 2000/3000 turn to lapping/polishing compounds , so another
$3-$7 for green or white (or both) buffing compound or diamond paste

plus some wood from your big box hardware store to use as a plate for the compounds or your leather
$1 for 10 pack of 1 gallon paint stir mixing craft sticks (plenty thick, 12inch)
or $1 for 3 pack of 5 gallon paint stir mixing craft sticks (thicker, 20+inch )

the stones from China will have to be lapped flat, so spend some additional money on a flat lapping stone. some of them are not as great as quality stones, but can get a sharp edge.

what steel types are you sharpening? any super steel or d2 you'll want SiC or diamonds

IMHO it would be good to just get Norton crystolon stones as they are affordable and work with super steel and already loaded with oil iirc.

I don't have those particular stones, but I would wager all the Chinese stones are pretty much the same. I grabbed a set of the cheapies just to see. And man are they cheap! They dish after every sharpening, and are not fantastic stock removers. They are ok for fill in work. But I wouldn't expect them to last very long. So all the money you think you are saving could quickly be spoken for when replacements are needed(which I guess to be after approx 4-6 knives). I have Shaptons for real work. I know they will last for many, many knives, AND THEN SOME MORE! I would recommend using Gritomatic stones. They sell some inexpensive aluminum oxide that I'm sure would work MUCH better than the Chinese counterfeits, err, I mean counterparts!

Hi,
You can also flatten stones against each other,
or the ultimate flattening/lapping kit
A $1-2 ceramic tile (or glass) from big box hardware store,
plus some loose grit

online there are lots of places that sell sic lapping powder

and I saw the other day harbor freight is supposed to carry locally
rock tumbling rock polishing silicone carbide powder in small amounts

dollartree has stones in stock again, they can work , and releasing grit from them is easy with a nail

Hi,
How much force are you using? How many pounds/lbs on a scale?
Is there a difference in dishing rate between the coarse and the fine?

Probably the most common comment about these its that they're crap or fragile ... and still

If you call this crap:

Then by all means send me whatever else you consider crap. This was sharpened up to 2k grit on the "crappy" chinese stones and then stropped up to 14k. I don't know why people keep saying they're bad, I've used 3 different sets of these stones and keep getting results just as good as the above edge. And that was S30V, not really considered easy to grind on. I've gotten even better results with elmax and other highly polish-able steels. And if I'm an expert, then holy crap, someone give me a better paying job.

I wanted to revive this as I have a question in regards to Venev Bonded Diamond Stone for KME. As far as flattening the stones, has anyone done this yet, has it needed to be done and what was the results? I've quoted this response in regards to tumbling silicon carbide polish for lapidary use, i've seen this one ebay. Would this be something you use? Would 50 grit be too much? I thought about using the back side of my DMT 95 flattening stone, the smooth metal side, using this polish with water to flatten these stones. And what kind of results have people had with these stones so far?

My understanding is that you can use SiC to flatten the stones but mine haven't needed it. They came pretty flat and remain flat after maybe 7 or 8 sharpenings. I have used a small Nagura stone with water to clean them but they seem to be performing well otherwise.

I’d recommend the real EP 120, 400, and 1k, then if you want higher polish, you could throw down on an SG 8k

That whole set is well under 100usd and will last through tons of knives. Personally, when I use my K02, After setting my edge, I use a 400 then strop on the SG 8k and it has given me wonderful results for relatively cheap—although the system itself was expensive af

I'm starting to think I should have created a new thread, I guess I mentioned this one in regards to the rock tumbling rock polishing silicone carbide powder for flattening these stones, Venev Bonded Diamond Stone for KME. I actually picked up the whole set of Venev stones, 60, 80, 150, 240, 400, 800, 1200 and 2000. I like the idea of using the same stone thickness, I have the stone compensatory but I like to stick with one kind. I have the whole KME gold diamond stone set also and it produces a good edge. I was kickin around the idea of a backup stone set when I saw the Venev and saw that it has the 2k stone. Biggest difference is they're bonded and can wear like a normal water stone which needs to be flattened eventually. I have a DMT 95 for my naniwa stones but I use water stones for kitchen knives, I like the even edges on my CRK's that are produced by the KME. I even thought about the chosera set from KME to get that smooth water stone finish.
