Washita oilstones are used by woodworkers around the world and they all come from a small area east of Hot Springs in Arkansas, USA.
Origins
Washita, and the closely related Arkansas stone, are both forms of a rock geologists call Novaculite. As this research shows, Novaculite was used by Indians to make tools long before...

If you pick up a wooden bench plane from the the last century (there are lots of them about still!) the chances are it will have a ‘laminated’ cutting iron (we are going to touch on some basic metallurgy with many mentions of iron in this post, so I will refer to them as ‘blades’...

Makers of edge tools, including plane blades, need to be concerned about several different properties of steel.
Steel Properties
Toughness: This is the ability of the steel to deform without breaking, cracking or chipping. Materials that lack toughness are said to be brittle. Note that sharpening angles have an effect here – the narrower the angle...

From the time Leonard Bailey introduced metal plane in the 1860s until quite recently they were supplied with thin irons. On paper this is a good thing: thin irons are an improvement on thick ones in as far as they are cheaper to make – since they use less material – and are easier to sharpen because...

Although this article is about blades used in wooden planes there is an interesting parallel between the blade choices available to wooden plane users at the start of the 20th century and the choices facing metal plane users at the start of the 21st who must choose between thick vs thin irons.

Once you’ve ground the blade to to about the right angle then you need to hone it in order to create a keen edge. The experience of generations of craftsman has shown that grinding the blade at 25° and honing a few degrees steeper – around 30° – is a good practical approach for many woodworking...

Once you have established the rough shape of the bevel the next step, referred to as honing or whetting, involves rubbing the iron against progressively finer abrasives until you are satisfied with the sharpness of the edge.
There are a couple of basic principles involved in how bench planes cut:
* The steeper the pitch of...

Traditional Methods
The traditional method for grinding a bevel on edge tools uses a mechanical grinder. This is the method typically described in historical woodworking books that explain the the methods of craftsman making furniture and joinery for a living.
Here are some extracts from the literature published in the 18th, 19th and 20th century...

Sharpening! A quick trawl of the internet reveals a bewildering array of opinions on this topic, and if you look a bit further afield you will find entire books covering the same. But don't be deterred: the basics can be understood and learned with a relatively modest investment in time and do not...

If you buy a new plane from Lie Neilsen, Veritas or some other high-end maker then you can rest assured it has been manufactured to very high tolerances and therefore won’t need any work (and if it isn’t you can always return it and ask for a replacement). However, in the event you...
