best sharpening stone for tools

A Veritas PM-V11 iron on a Soft Arkansas from Dan’s Whetstones. The steel sharpens quite well on the oilstone.

When steel and an abrasive intersect, the typical result is utter confusion.

Today we have more choices in steel than ever before. The same goes for abrasives. And so wading into the issue of what abrasive to use with what steel is a subject that should be a book – not a blog entry. (If you need a book on sharpening, get Ron Hock’s “The Perfect Edge.” It is $20 well spent.)

All I want to do with this blog entry is to dispel a myth that oilstones can be used only with high-carbon-steel tools (aka O1 or W1). Good oilstones can sharpen A2, very hard Japanese tools, Veritas’s PM-V11 and other stuff. Lame oilstones can barely sharpen tin foil.

Why? Well you can look for the answer in a forthcoming article by Larry Williams and Don McConnell in the February 2013 issue of Popular Woodworking Magazine. Williams and McConnell went out into the novaculite fields in Arkansas to learn about this amazing material.

Both Williams and McConnell are fans of oilstones and use them in their work at Old Street Tool. And the article makes a compelling case for woodworkers to give them a second look.

On Williams’ recommendation, I purchased a set of oilstones from Dan’s Whetstones about two years ago and have been gradually easing them into my daily sharpening routine. These oilstones are not the oilstones I grew up with (even though I am from Arkansas). They are, quite simply, excellent all-around sharpening stones. Here is what I bought:

• Soft Arkansas, for initial honing – erasing the old edge and cutting a new one.
• Black Hard Arkansas, for initial polishing.
• Translucent Arkansas, for final stone polishing.

Buy sizes that suit your widest plane iron and your wallet. The wide and long stones are considerably more expensive than the typical 2” x 8” stone.

Dan’s Soft Arkansas can easily sharpen O1, W1, A2 and PM-V11 with no problems. An A2 chisel takes about 10 strokes or so with firm pressure. The two polishing stones do a nice job of removing the scratch pattern from the Black Hard Arkansas and the Translucent. You can then strop if you want a mirror polish. I usually don’t strop, except for when sharpening my paring chisels and my smoothing plane iron.

However you might not get the same results with other oilstones. I have some vintage Nortons, a Queer Creek stone and my grandfather’s Craftsman Soft Arkansas. These stones do OK on O1 and W1 steels, but they don’t seem to work on the more modern steels or super-hard Japanese steels. (Yes, they had been dressed on a diamond plate.)

After demonstrating my oilstones to Executive Editor Megan Fitzpatrick, she tried using her grandfather’s oilstone to sharpen A2. No luck. (Yes, it had been dressed with a diamond plate as well.)

Conclusion: Not all oilstones are created equal. I cannot tell you what other brands of oilstones will work on modern steels. If you want to buy some other brand, my recommendation is to first try your tools on the stones before you buy them. Yes, this is tricky to do through the Internet, even with a 50mbs connection.

The point I really want to make is that you don’t have to have waterstones if you have A2 in your shop. Yeah, the waterstones might cut faster, but they also make a bigger mess and many need soaking before you can get to work. And you have to be extra careful to wipe your tools to prevent rust.

A good oilstone is something to be cherished, like that Buck Bros. chisel that holds its edge all day, the hammer that never dents your work, the saw that always cuts smoothly.

    I think it would be a safe bet that those on a waiting list for one of Larry and Don’s planes would rather them be in the shop clearing back orders rather than touring novaculite fields in the central part of the state with the almost inevitable ‘academic’ pant-wetting sure to follow.

    I have had good success with a two-sided stone (soft/hard Arkansas) I got from Hall’s Pro Edge. They’re very reasonably priced, especially compared to the diamond stones I’ve been using. I’m keeping a coarse diamond stone around for a while, but the Arkansas stones are becoming my go-to sharpening method.

  • muthrie

    Ok, I know I’m probably missing something, but I’m trying to reconcile the comments in the Dan’s Whetstone article that says:
    “To work, abrasives must be harder than the material you are abrading. With a Mohs hardness of 7, Arkansas stones are slightly softer than the carbide inclusions in some of the steels used today. Arkansas stones don’t work on steels like A2. Woodworkers who prefer A2 steel cite its abrasion
    resistance.”

    What did I miss? I know I’m going to look stupid, but I’m ok with that.

    I am confused as Chris says “The two polishing stones do a nice job of removing the scratch pattern from the Black Hard Arkansas and the Translucent.” Does he mean that the polishing stones remove the scratch pattern from the soft?

    I confirm that Dans are great to deal with. It is just the carriage charges to England that kills the deal so I am hoping Classic Hand Tools will stock them.

    Thanks Chris. Bernard

    I am glad you are talking about oil stones. I have always used them and dont have any plans to switch to water stones. I have a bunch of vintage stones, some man made, some natural arkansas. I am getting ready to upgrade now because I broke my best stone beyond repair. How do you like using the Norton India Stones. They have some new ones that are 3″ wide. They are much more affordable than new Arkansas stones.

    I know literally nothing about oil stones, but I’m curious. I would gladly trade a few more strokes on the stone for no flattening and no water mess. Plus due to a move, my shop space doesn’t have running water any more.

    Do they require flattening like a water stone, but less frequently? If so, on what? Diamond stone?

  • Rick_S

    Chris,
    I am curious why you think Arkansas stones are better for sharpening that diamond stones?
    Thanks in advance for your advice – I always look forward to your next blog.

    I’m curious to Chris, about which stones you picked. Pissed off too that you keep telling us about all these good, expensive tools. Well, not really, but my list of good tools to buy never seems to get any shorter!

    Dan lists the hard black and the translucent both as “extra fine”. Is there much difference, b/c there sure is in price…

  • Brett

    So, how can I tell if my existing Arkansas stones are any good?

  • GoodellPratt

    I have several stones from Dan’s Whetstones (a great guy to deal with BTW) and can tell little practical difference between the surgical black and translucent white. I usually just go from black to strop. Being a natural product, there can be variation between various deposits of the stone. I think the difference between these two grades is really one of preference rather than performance.

    I’ve been using Norton and other Arkansas stones for years with no problems at all on A2 or otherwise. My go-to stone is an old Pike Lilly White Washita. I can come off it and go back to work. Somtimes I will refine the edge further with a black hard and a few strokes on a hard strop.

    I’ve never liked the idea of waterstones; too expensive and have to be frequently flattened. And then there’s the whole moisture and metal thing…

    You may be too young to remember this, but back in the ’70s Buck Knives sold a sharpening stone set advertised as having an “Arkansas” stone. The set included a small white stone, about 1 inch by 2 or 3 inches, and a dark stone that was larger. The kit also included some honing oil. I wonder what kind of stones those were?

  • therealbird

    Damn you Schwarz! You just cost me too much money with all your reasonable arguments about why stuff is good. Now I need to buy these fancy oilstones (not that I wasn’t conviced by my Grandpa’s small translucent one from the get go. At some point I will need to send you a picture of my wife so you can avoid a painful run-in with her when in Germany…
    Anyway: Thanks (as always) for the good tip.

    I typically go from my India stones straight to the translucent.

    My current stones are a set of Norton India Coarse, Medium and Fine stones and a wonderful Translucent Arkansas that I got from TFWW that changed my sharpening forever.

    Before I got these stones, I had probably half a dozen stones I’d picked up from various flea markets and tool shows that really didn’t cut any kind of metal. I experienced pretty much the same feel you did, not all stones are created equal and when you find one that does work it’s like a light bulb going off. I actually enjoy sharpening now.

    My typical sharpening regime is as follows:

    For a touch up, just the hard translucent and maybe stropping on leather with green paste.

    For restoring an edge, 10-15 passes on the Medium India, then straight to the Translucent. If it’s pretty bad, I’ll run through each of the India stones in succession.

    My carving chisels get frequent touch ups on the translucent, and regular honing on the strop.

    I like Oilstones, but I can see the appeal of Waterstones and their quick cutting. I like them more because I’m more of a historical kind of guy and the 16th – 17th century joiners used Oilstones. Plus, we have enough issues with water here in Seattle, oil seems like a much better idea.

    How much benefit do you see from the translucent after the black? I’ve been going straight from the hard black to the green crayon on leather and have been generally pleased with the resulting edge, but have noticed it may not be quite as keen as what I get coming off a Chosera 10k.

  • ebushee

    Do you feel you need for the black in between the soft and translucent? Or is it like putting a 4000 grit waterstone in between a 1000 and an 8000?
