Is it necessary to clean the flattening stone after used? I've used once and leave some color of the grit water stone on it, will it affect to the quality of flattening?
Well one thing the video doesn't tell you is that you're supposed to use the whole stone when sharpening a blade. If you're constantly using the middle and it causes the stone to be shaped like that, it won't last very long. Especially with the lower grits that are essential for removing chips and rust. Using the whole stone will give you longer strokes too, which helps sharpen more efficiently. Base your need to flatten on those aspects; hope that helps.
Agreed. And the is some mystique in the need for a 100% flst stone in the first place. I made knife sharpening into a hobby for family and friends and Im getting my practice and production runs. My stones do get used and indeed the coarse / lower stones get a serious beating, since most kitchen knives arrive pretty banged up. I have an old broken stone that I simply do not flatten. The only fkattening it gets is a) using the whole stone, b) using the sides when working tips and bolstets and c) that what rinsing brings. Which shouldn t be excegerated either. Works like a charm. Fkattening onky works in favour of the ones selling stones ...
Well. Use your knives during sharpening as flattening. Use the sides well and work sides and top/bottom when working tips and bolsters. You don t need 100% flat stones. They are so only once in their sharpening lives, eg only the days before use ... Flattening is sort of nonsense, only catering for selling new stones. I tried once. Ive lost maybe 1 mm during 10s of sharpenings. Ive lost neirly 2 to 3 mm from one flattening session. As shown in this vid. Don t flatten. Your flattening stone is a product for use. Not an object for 100% Japanese style purrfection ...
Hello, i have tried this with a coarse diamond stone and it really just makes a flat useless stone. There is no bite of any kind on the sharpening stone. It is a smooth 100 grit stone lol. How “brand new sandpaper” does the stone feel after using that particular flattening stone? Cheap stainless ruins diamond stones and the coarse ones are expensive compared to the readily available alox coarse stones. Id rather have a norton or something disposable but i want to be able to re flatten it. Thanks
Are you saying you rubbed the lapping plate against a diamond sharpening stone, as in one made of metal, because that sounds dumb to be honest, you just sanded off all of the abrasive parts.
Huh? Diamond stones have an ultra thin diamond sharpening layer and do not need flattening. They only need a rinse every now and then. You probably have very successfully removed the sharpening diamond particle layer of your shaprneing stone, leaving - eeuuuhhhh - indeed just a flat layer that someday held your precious diamond sharpener ... This flattening only works on sharpening stones. But even then: sharpening stones take away very much material and you are actually destroying your own stone using them. You are actually rubbing two sanding layers against each other. You are achieving not much with regards to sharpening, but you are greatly helping the economy!
I had noticed that, while flattening my 400 and 1000 grit stones was easy peasy, my 3000 and 8000 grit stones took several times longer to flatten, despite having much less dishing. Is that normal, and is there a reason for it?
Yeah. The stone is flat. And it's almost gone now ... The selling trick here is that flattening a stone removes sharpening and flattening material: you are greatly helping the economy and the shops turnover. When you carefully use the entire sharpening stone each sharpening, you are practically discarding the need for flattening. Cleaning your stone of gunk: yes. Flattening? Naaaahhh .
@@AGH331 Agreed. Flattening is usually done a) using the whole stone and the sides as much as possible, b) working the edges and top/bottom when working tips and bolsters and c) during cleansing. Which shouldn t be excegerated either. I do not flstten stones anyway. 100% flatness needed is nonesense anyway.
Nice job. That did not take as long as I thought it would. Thanks.
What do you do when your flattening stone becomes convex?
Instructions unclear
Flattening stone became an parabolic mirror
Flatten it with another flattening stone lol 🤷♂️ 😂
Excellent demonstration 👏😁
That intro made me think I was watching an old dreagast video
The lapping stone will get convex with time, what do you do then?
Flatten it with a diamond plate or sandpaper i guess
my Norton stone said to use water proof sand paper!
Well every four to five whetstone's it's recommended that you flatten it with another lapping Stone.

Clean tools are safe tools
Nice! Thanks
If you were to flatten every 3-4 knives as suggested, how long would you say these stones could last?
Yeah I was wondering the same thing

Thank you for your video! I got the same kind of stones from Amazon, but a different brand. And, then the damn thing didn't have any instructions.
I noticed using your stones in the cold or cold water wears them out quicker
use how many grit stone to flattering #400 whetstone ?
Flattening stones are typically 180 grit. I use mine even on my 220 grit.
Well.

You need 3 stones, all 3 become perfectly flat in a pinch; 2 stones *won't* do!!! look it up
Jose Peixoto what??!!??? Three stones .. what in the hell are you talking about ?

Maui Randall no i dont think thats what i was saying. It was a year ago i dont really remember.

Because the 400/1000 stone is super soft.
tcp3059 higher grit = more dense
You take off more grit with lower grit stones because the particles are bigger.

Try using 'the entire sharpening stone' when you sharpen chisels and plane blades ;)
