Technique > Gear.

A coarse stone (<300), a fine stone (>600), and a leather strop with polishing compound are all you need. The rest is all about keeping a consistent edge angle. Don't be ashamed to use a jig if your freehand skills suck.

Unless you are doing a literal shaving razor, then more is justified.

I use 120, 320 , 600 then I have a strop on a glass strip with taped 1500 sandpaper(i rarely change it so it's very worn off) on one side and paper with polishing compound on the other side. If I want it a bit finer after the 600 I pass it on makita 1500 and then to the strop.
And if it's a kitchen knife after 300 I directly go to the strop.

>> No.1495000

Start with a Norton IB8 and get fucking good with it. Once you can shave arm hair without scraping, get a finer stone.

It is a waste of money to buy stones before you develop technique. When sharpening you receive a constant stream of feedback from the stone, and all stones give different feedback.
You will know what you need once you can make use of it.

>> No.1495004

The key is using a strop. You can even just use a basic sharpening stone like the puck ones on Amazon. More important is getting your angles right which depends on the blade. To get good at this use a sharpie on each side of the edge of the blade and slowly change the angle until the sharpie starts to get rubbed off and get used to keeping your hand at that angle. Then use a strop and use it after every use of your blade to keep it as sharp as possible and decrease the need to use the stone.

Grits are not standard across stone "types."

Water stones have an inflated grit number. Or Oil stones have a deflated grit number, whichever you prefer. This means a 15k waterstone is roughly equivalent to a 3k ruby ceramic oil stone. A black arkansas is in this range as well. Sandpaper also has inconsistent grit rating but where it lies depends on which country standard the manufacturer follows.

Stropping creates a micro serration. This is for knives/razors ONLY. For chisels/handplanes/etc you want either a very fine stone or lapping film on a hard surface. Do not use polishing compound. It's not for sharpening. Stropping compound is only good if the manufacturer has it at a specified micron. Don't "strop" on a buffing wheel either. All that bad shit will only improve an edge if you sharpened wrong in the first place.

That said, the minimum I would recommend for a homeowner is actually simple and gives you a decently sharp blade without autism:
A powered grinder with coarse wheel. Whatever you can get for cheap, if that means the first you find is an old cranked grinder at a flea market then get that. You don't need to bust out the CC for a tormek if you pay attention. Make sure it has a usable tool rest. Protip: Don't quench hot tools in water unless you can dunk them tang-first. You can cause micro cracking which will make the thing dull quicker as you use it. Just swap to a different tool while that one air cools.

A coarse norton crystolon stone.
A medium norton india stone.
And a reasonably flat brick the same width/length. Flatten one with the brick then flatten them against each other. You need 3 stones for it to work.

If you have no self-contained work area, like living in an apartment, get a B&D Workmate so you can do it outside on a relatively stable surface. Extension cord and small enough grinder if you're close to ground level, cranked grinder if you're SOL on that regard.

Please hold small items to the grinder using locking pliers and wear PPE

>> No.1495275

as other anons said dont go full autistic get a coarse one and a fine-ish one or if you dont plan on restoring much get a double sided one medium-fine and low grit sandpaper when you are establishing bevels and repairing tools

Thread reminded me I needed to flatten my stones.

Dont buy a flattening stone. They are all shit, they wear out too fast, and then you have to flatten your flattening stone. Just pick up a piece of granite and some 220grit. Mark your stone with a pencil and rub it back and forth until all pencil Mark's are gone. You can bevel the edges if you want. But these are for my straight razors, what are you sharpening? If it's just kitchen knives I just use my belt sander with 1000grit belt. Super fast and easy.

You need 3 surfaces. A, B, and C. A is your stone, B and C are flattening stones, which can just be big enough bricks, flattish rocks, or one being a different stone. Don't buy a flattening stone for oil stones, they're for waterstones. Rub B and C together until reasonably flat. Rub A and B together until reasonably flat. Rub A and C together until completely flat. You need to have a common plane between 3 surfaces, using only two will make one concave and the other convex. Even sandpaper on glass will wear unevenly and cause issues.

This is how a surface plate is made, by the way. They just do it with granite or cast iron.

If one is seriously dished like the old one in picrelated you will need to grind it down on the sidewalk or something til the points of contact are not so narrow, then you can go as before.

You don't want to do this with belt grinders/sanders btw, since it will kick up a shitload of dust and load the belts real quick.

>>1495643
Flattening stones are for water stones and you need to flatten them for the reason I said before. They're grooved because water stones wear very quickly and the grooves allow the slurry to escape. I am not a fan of water stones because of how quickly they wear down. They do cut pretty fast but that's a minor issue compared to spending so much time flattening them in between.

>> No.1495669

Pretty much what >>1495658 said. I'd get the cheap sharpening stone from HF and just go to town rubbing them together, if your Arkansas stone is really fucked up untill it is pretty flat, then finish it with the granite and sand paper method. You can wet sand it in the tub or sink. Just make sure the sandpaper is wet sandable. Lots of elbow grease.

Funny you mention that. The HF/dollar tree/discount oil stones are actually serviceable in and of themselves. The catch is they require you to soak them in at least an entire bottle of mineral oil for days so there's a hidden cost behind them, and the size is kinda shitty. If you don't do that they clog real easy. Not worth compared to a proper stone.

Lapping plates work great. I won't name mine unless asked because I have had several and they all seem to work well with mildly varying degrees of durability (corrosion and surface efficiency). Some take slightly different techniques to be most efficient with, but it's pretty simple in all I've used. I will say that I've never used a sub $50 one, aside for the fact that they were much cheaper than that when I first started sharpening as a kid, so I can't vouch for those. I avoid them because I have used honing rods with similar surfaces to the cheaper lapping plates, and those like to wear out stupidly fast.

Diamond plates?

>> No.1496466

>>1496374
Only DMT or Dia-flat are worth it. The exception is if you're just sharpening utility/camping/standard kitchen knives which don't need 100% flat exactness. They wear out faster than oilstones but you will never see some people talk about it because the durability difference is on the magnitude of decades. Oilstones cost less up front and while you do have to buy mineral oil you should have it anyway for cutting boards, lubricating food-contact machines, and as a general purpose "safe" oil.

Dia-flat will last up to 5 years or so depending on use.
DMT will last up to 15.
Cheapos maybe 3 years.
Oilstones, depending on thickness can outlive you as long as you keep them flat and don't drop them.

Diamond plates will gradually cut slower and finer as the diamonds wear down. DMT uses monocrystaline which means they break down at a slower rate than dia-flat or the cheapos. I don't know about how good norton's diamond plates are.

Paul Sellers is a great guy but he's not correct on everything. He's wrong on sharpening, what a (modern at least) cap iron/chip breaker does, and he claims cast iron planes will flex when you try to flatten them if they're not done assembled.*

Here is a sharpening autist that goes into WAY too much work for a perfect woodworking edge: http://www3.telus.net/BrentBeach/Sharpen/sharpen.html

He also compares different steels.
I don't follow all his shit because going through loads of lapping paper isn't in my interest, but I will never strop my tools again.

It depends.
First off grits are NOT standardized among countries, so you can't say a 1000 grit is the same for an arkansas stone, a japanese wetstone or a piece of abrasive paper. It varies a lot even among brands, and for high grits it's wild west.

This said, do you want a set to mantain already sharp knives sharp, or to restore dull or damaged blades?
In the first case a single combo wetstone like an 800/1600 or 1000/3000 (and everything in between) and a strop is all you need. Of you don't have leather a piece of denim make a very good strop.
In the second hypothesis you need to add something like 150 or lower to restore geometry and something around 400 to prepare the blade for the sharpening. In this range you might consider getting diamond stones: they stay flat, cut fast and last long if well built. A good and not very expensive brand is Eze-Lap.

Depends. Grit sizes mean different things for different kinds of stone.

Diamond: DMT (anyone try ultrasharp?) See pic.

Arkansas: see Dan's Whetstone's, the site has an explanation. Basically all novaculite Has the same grit size, and the difference is the density of how the grains are packed.

Waterstone: start with Norton. That's what people usually mean when they say grit. Shapton if you have tons of cash.

Scarysharp: wet/dry sandpaper in various grits, plus a piece of plate glass and some spray glue. You need to go to higher grits w sandpaper than a waterstone.

Get a sharpening jig. I'd start with scary sharp and master that. Once you're used to it, you'll know what to go with. They'll all work, it's just a balance of speed/convenience/money. For oil and especially waterstones, you'll need to flatten the stone to fight dishing, usually via a diamond lapping plate.

I prefer diamond stones. They last forever (in my case, 12+ years so far), don't need to be trued, and only require water (Sellers suggests Windex). 325 to create or recreate the bevel if necessary, then 600 and 1200. Then strop. Usually start with just the 600. There's a medium extra fine 4000 plate that I want to try. The plates are all good to within a thou; I don't see the point of the lapping plate that's good to half that when it's so much more $$$.

Don't worry about stropping yet. Just get the basics down.

I mainly use a cheap 400/1000 diamond plate and a DMT 8000 grit.
something to consider is that the high hardness of diamonds make them to cut deeper than regular stones so the 8000 diamond actually produces a less smooth finish than a 3000 grit oilstone.

They cut wood. He does it consistently so he gets a good edge. Most people are fucking awful at sharpening, hence the seeing of gains from stropping.

The advantage of using a super high grit stone or lapping film to hone your edge is that you barely, if at all, have to sand the piece after, and the methods in the link above make it take very little time. It also provides you with an assurance that your blade is evenly sharp all across and will reduce tearout in complex grain.

It will also slash through the wood with greater ease.

Just to chime in before anyone ruins a nice razor on a coffee cup or brick- don't do it. I don't know how the Chinese water stones are, but 20 years ago an 8K Jap stone was considered ultra.

Dear Sharp bois, I need your aid.

I recently got into straight razor shaving, and instead of buying a new one, I asked my dad and he pulled an old one of his out and game it to me along with a strop and this old looking water hone. However, no matter how much I try to sharpen it on the stone, it just doesnt seem to get sharp enough. Could the blade be too old, or something wrong regarding the stone? (Ive tried to follow guides online on how to sharpen it, so I dont believe its from wrong technique.)

How are you using the hone? You want to lay the blade down so the spine is in contact as well as the edge, and stroke edge-first. Flip over (keep the spine in contact and flip over the spine), stroke, flip stroke. If the edge was abused this could take some time. It should be able to slice a hair held in the air before going to the strop.

Yes. Get a 240/1000 grit whetstone. Then strop on an old pair of jeans. You can get and keep your knives razor sharp for $15 total.

Ive been doing that. But due to tue age of the blade and lack of use for so long iam guessing it might just need a lot more sharpening. I also dont have any harder grit stones to start with before this one. So for now ill keep hacking away with just this stone.

From this post it becomes clear that you don't know basic stuff about sharpening (this is not an insult ) and sharpening straight razors is even a bit more complicated than sharpening knives. Also you are asking for advice when there are so many good videos , where you can see how exactly it's done.

Maybe you need to apex the edge on a bit lower grit and then hone it and strop it.

Dude I sharpen and make knives for living. Believe me , this is not a viable way to sharpen a knife. The surface is so small that at the second pass with the blade, it will be clogged with metal and it will stop removing material. Don't believe to everything you see on the retarded '' life hack'' videos on the internet

belt sander. not a joke, $300 motorized knife sharpeners are literally purpose-built belt sanders with a guide to hold the knife at roughly the correct angle.
get a cheap belt sander, use a ceramic belt 150-250 grit, mount it to a bench, hold the blade angle right and that'll be enough to cut your vegetables.
people use belt sanders to sharpen chisels too.

I agree , its one of the fastest and easiest ways. You only have to be careful with the overheating or over grinding.

Harbor Fright sells a 1x30 sander for $30

You can get a lot of different grits, but personally I find two passes on 180 will bring back a dull but well maintained knife. Then I use a fine India or a Hard Arkansas to finish it off.

How are you supposed to develop a technique without using a stone.

That's a really basic, high quality, and affordable stone. He's saying get one, get good with it, then go nuts buying all sorts of fancy shit.

I like my 4k/8k water stone.
$20 off amazon and it gives my hobo stabbers a hell of a polish.
