Looking for coarse waterstone

[jnbrown]

Hi,

I currently have 600, 2000, 5000 grit stones.
I use them for my kitchen knives and woodworking tools like chisels and plane irons.
There are times where I need a coarser stone to restore badly mangled edges.
For example just bought a vintage Stanley hand plane and the blade has some bad chips and it is cambered and I want to make it straight.
I have been working it on my 600 grit Chosera and made some good progress but it is going slow.
I am thinking something like a 220 grit to get the primary edge established.
I found Naniwa standard and lobster and Shapton.
Any others I should consider?

Thanks

I am very happy with my Shapton Pro 320.

A 140 grit diamond plate is not just for maintaining your stones. I also use the 400 grit Atoma pretty regularly to reset bevels fast. You never have to worry about a diamond plate being dished.

I have the CNTG 140 grit diamond plate that I use to lap my stones.
Would sharpening steel on it wear it out or damage it?
Is the Atoma 400 grit better than a 220 grit water stone for this?

Thanks

Have the same 140 plate from here. Wear it down, yes over some time. Mine is very slow wearing. Damage it, no. Mine hasn't taken damage from repair/thinning sessions and I've probably put about six hours into thinning. There doesn't seem to be anything like diamond loss or dislodging at all. Mark got those built pretty high quality IMO, especially compared to others I have used.

Sharpening on 140 is pretty aggressive though, and would really be used for something like chip/edge repair. For just establishing the bevel edge, I also prefer something in the 320-400 range. Latte 400 is my go to right now.

Given what you've got & what you want to achieve, I would suggest either a Shapton Glass 220 or a Shapton Glass 320.

If I had to go one way or the other, and you could wait, I'd suggest the 220, but unfortunately it's OOS ATM.

Also found this one recommended:

SIGMA POWER SELECT II WATER STONE - 240 GRIT

It is a bit more expensive but willing to stretch if it is worthwhile

Edit - forget that one sold out

Amazon has the Shapton 220

I think if you are going Shapton Glass a lot of people prefer the 320 to the 220. The 220 dishes really fast. I have both and never use the 220 unless I have to. I would rather use the 140 to 400 diamond plates actually but that's me. At this grit I just want to get the work done. Save the fun for a little higher up.

I like the Glass Stone 320, but recently went to mostly diamonds for sharpening. Less dishing issues!
