Tips On Buying Woodcarving Gouges


In this article, Jim Hingst describes a common sense way to buy gouges and other wood carving tools, and explains the terminology used by the manufacturers.  

By Jim Hingst

Before you order a complete set of wood carving tools, please read this article. In the first place, there is no such thing as a complete set.  A typical set of wood carving tools includes from 6 to 18 different gouges. A tool manufacturer, such as Pfeil, has a product range of a couple of hundred different wood carving tools.  Now that’s what I call a complete set! 



The distributors and manufacturers of gouges will promote buying sets of tools as the most economical way to buy an assortment of gouges at a fantastic price. In a way they are right.  At an average cost per tool, the price can’t be beat. The problem is that the so-called complete set of tools will probably include some gouges that you will never use. And on top of that, I can guarantee that the set will not have everything you need.  


A more sensible way to buy wood carving tools is to only buy the basic tools required for the particular type of carving that you will do. Then add to your collection, just buying the tools that you need. The tools that you will need to do relief carving will be quite different from the tools that you will use for carving letters. If you want to know what you will need to carve a sign, my advice is to ask an experienced sign carver for advice. If you want to be a sculptor, ask a wood sculptor what he uses.


Buy the Best Woodcarving Gouges and Tools You Can Afford. 


At the time you ask an experience carver what type of gouges he uses, also ask what brands he recommends.  Some of the best brands include Henry Taylor, Ashley Isles, Dastra, Pfeil, Stubai and Two Cherries. I own tools from each one of these companies.  None of the tools from these manufacturers is cheap. Prices typically range between $30 and $50 per gouge.  

Wood carving tools from any of the premier manufacturers are worth the investment. If you care for these tools, they will probably last your lifetime. And you can pass these tools on to your children (who will most likely sell them at a garage sale for pennies on the dollar).  Whatever you do, do not buy on price. And do not buy used tools on e-bay sight unseen. In both cases, you will probably end up with junk.

The overall size of professional woodcarving gouges is generally 9” to 12”.  Gouges made for hobbyists are much shorter. I suggest buying the best quality professional grade tools that you can afford. In shopping for woodcarving chisels and gouges, many of the terms used to describe the tools can be confusing to the novice. To help you shop for the right tools, I have defined some of the basic terms that you will encounter.

The Sweep of the Gouge.  


The sweep or cut of the blade refers to its curved profile of the cutting edge and is expressed as a numerical value.  The straight cutting edge of a chisel has a sweep of #1.   Blades with either a #2 sweep or a #3 sweep have only a very slight curve to their cutting edges.   As the number of the sweep increases, the curve of the cutting edge becomes more pronounced. A narrow width #11 gouge, which has a “U” shaped cutting edge, is often referred to as a veiner, while wide width #11 gouges are called fluters.




The sweep describes the curvature of the cutting edge, expressed as a numerical value. The cutting edge of the #3 gouge on the left has a very slight curve.  The #10 gouge in the middle has a very pronounced cutting edge.  The V-Parting tool on the right combines two chisel blades in one tool joined at a 60 V-shaped angle.  



The Sheffield or English and Continental Numbering Systems


Please be aware that numbering systems can vary from one brand of wood carving tool to another.  In particular, the nomenclature used to identify gouges by manufacturers in England differs from that used by manufacturers on the continent. To illustrate the difference, please refer to the chart below comparing the numbering systems used to identify the cutting edges of straight gouges.

Shank. Gouges are also available with shanks that are either straight or bent in different shapes.  The most commonly used chisels and gouges have a straight shaft with a uniform width along its entire length. 

Some gouges feature straight narrow shafts, which are flared at the cutting edge. These are called fishtail gouges.  Used to make deep cuts, long bent gouges feature a shank which is bent along its entire length.   Gouges, which are only bent for the first third of the shank, are called “spoons”.  Spoon gouges are useful for scooping out wood in tightly confined concave spaces.   Back bent gouges, which have a shaft curved with a reverse bend, are designed for cutting convex shapes.


The shank of long bent gouges, pictured on top, is bent along its entire length, spoon gouges are only bent for the first third of the shank, pictured on the bottom.

Tool Handles. Wood carving tool handles vary in length, circumference and shape from one manufacturer to another. Handles of gouges and chisels for tools manufacturer on the European continent are typically octagonal.  Wood carving tools manufactured in England are generally round. Pictured in the photograph below are gouges from six manufacturers showing the differences in handle design.  Some carvers prefer the octagonal shape because it prevents the tool from easily rolling off of a table. They also believe that the octagonal shape gives them a better grip. Personally I like tools with longer and thicker handles, because I have very large hands and the bigger handles are easier for me to grip. 
Note the difference in handle design among the gouges in the above photograph.  Beginning at the lower left, the brands of gouges pictured are Stubai, Dastra, Two Cherries (Kirschen), Pfeil, Henry Taylor and Ashley Isles.  The Two Cherries gouge has a steel ring or collar at the top of the handle, which helps prevent the wood from splitting when used with a mallet.

Rockwell Hardness. Manufacturers will sometimes specify the hardness of the steel used in the manufacturing of their tools. Measurements of hardness are expressed as a numerical value on the Rockwell scale. The cutting edge of the gouge must be hard enough for carving harder woods, but not so hard that the steel becomes brittle, which makes it prone to chipping. The ideal hardness rating for woodcarving tools is between 58 and 61. 


Wood Carving Tools for Sign Makers



For basic sign making projects, you do not need many wood carving tools, when you get started. Having a V-Parting tool is indispensable for most jobs.  If you are carving incised letters, I recommend having an assortment of #2 straight gouges. These are some of my favorite tools. For carving designs in relief, #5 and #7 gouges will allow you to make deep cuts to quickly and efficiently remove excess wood. Below is a list of some basic tools for sign makers.  As you continue carving, you will gradually add to your collection.


V-Parting tool 8mm


#2 6mm gouge


#2 12mm gouge


#2 18mm gouge


V-Parting tool 8mm


# 5 6mm gouge


# 5 12mm gouge


# 7 6mm gouge


# 7 12mm gouge

  1. Thanks for your insight. I'm still in the early stages of woodcarving and still busy on buying gouges. I started to make some spoons with a single gouge and a knife after some time I found that I was missing the right tool for a specific job so I bought a second. This process is still up to date, I buy a gouge when I have a need for it. Never walked out of a store with two gouges.

    Best regards,

  2. Great article. I'm new to wood carving. I'm interested in carving faces into wood (example: https://img1.etsystatic.com/011/0/5922276/il_570xN.428825285_reli.jpg). I don't have a large budget. Maybe $100. To create faces like this, are there maybe 3 tools that you would consider to be essential? Thanks for your help.
