Good Afternoon Bladeforum,

I hope you all are having better weather then New Bedford is, its raining and I still have yet to go for my daily walk, its going to suck!

My question for the group is...
I have a Japanese water stone that has writing on it. The writing is raised enough so that I can feel it when I slide my handover it. I can only assume that this will affect the sharpening abilities of the stone. So how do I correctly remove said writing?

Also, how long should (and also can) the stone be left in water before sharpening? I have been told to leave it in until the bubbles stop. Am I ok to leave it in for longer? Say if I had to run an errand and wanted to sharpen when I got back. Would it be ok to leave the stone in water for an hour or so or would I damage the stone?

The attached picture is the stone in question although its Amazon's picture.

Thanks folks!

Brad

If it's not mounted to something... sharpen on the other side. If it is, then you may need to lap the stone to remove the writing.

You can "oversoak" a stone... depends on the type of stone it is. (Not sure what that one is).

First off, thanks for the reply.
Secondly the stone is actualy a 1,000/6,000 stone so the opposite side is not the same.
Thirdly, what does "lap the stone" mean?

Here is alink to the exact product.

(Mods if this is inappropriate, I will apologize in advance and remove it if needed.)

Thanks again,
Brad
 
Get it wet and use it a few times, the writing will come right off.


- Fully immerse whetstone in water and soak until bubbles no longer appear (+/- 5 minutes).
- Using the #1000-grit side, slide the blade edge along the stone at a 10-20 degree angle applying consistent light pressure. Maintain steady angle on both sides for best results.
- Alternate sides each stroke or every 2-3 strokes.
- Sprinkle more water on the top of the stone to ensure the top surface remains wet.
- Repeat using the #6000-grit side until your knife is as sharp as you want!
- Wash the knife with hot soapy water to remove debris and rinse the whetstone to remove grinding residue. Allow to dry 48 hours before storing.

Seriously? Why?

Hi,
hot water has no benefit , its just wasted heat,
Hot rocks/bricks expand,
hot rocks are easier to break,
waterstones already have a weak bond ,
whether its resin bond or clay/ceramic bond or other
heat makes it weaker...
and if you rapidly cool a hot stone you'll get cracking for sure (thermal shock)

I was washing a few dishes before and I never even thought about expansion or contraction as an issue with a sharpening stone. Thanks for the info.
