Japanese Carving Tools for Woodblock Relief Printing

You won’t need many tools to start carving woodblock panels for relief printing. You probably could get by with an Xacto knife and the gouges that you use for sign carving. But if you want to do some intricate work in the tradition of Ukiyo-e woodblock printmaking, a few Japanese carving tools are a worthwhile investment. An assortment of some of the traditional tools is pictured in photo A.

Video about Japanese woodblock printing

There are many different types of Japanese carving tools used for woodblock carving. Most of the individual tools are comprised of three parts: a hard wood handle; a brass ferrule; and the cutting blade.

Some of handles used in making professional grade carving tools are comprised of two parts, as shown in photo B.  The handle comes apart by removing the brass ferrule, exposing the blade. This feature allows the blade to be easily adjusted or removed for replacement.

Hangi To Carving Knife

In woodblock printing, the first steps are to transfer the pattern to the wood panel and then to cut along the outline with a carving knife. This knife has an angled blade and looks like a woodcarver’s skew chisel.

The traditional Japanese Hangi To carving knife utilizes a single bevel blade. One side is flat. In cutting the wood, this side should be against the wood that will be retained. The beveled edge is positioned toward the waste side of the wood.  Both right hand and left hand carving knives are available.

For more detailed information read my story about  Japanese Hangi To Carving Knives.

 
U-Gouge

After a design is outlined using a traditional Japanese carving knife, the next step in carving a woodblock panel is to remove much of the waste wood using a Komasuki U-Gouge. These gouges are very similar to the large woodcarving gouges used in sign carving. While these Japanese gouges are available in several sweeps, a 8# sweep gouge is frequently used. The #8 sweep allows for deeper cuts, than shallower #3 or #5 gouges. In removing waste wood, you will want deeper cuts as the distance between the outlines increases. The deeper cuts allow for the paper sagging in large open voids in the woodblock and prevent the paper from being contaminated with ink in these areas.

Bull Nose Chisel

After removing most of the waste wood between the outlines, use the bull nose chisel to carefully remove the remaining waste wood adjoining the cutlines. Aisuki bull nose chisels with a flat blade are available in a variety of widths, including 1.5mm, 3mm and 6mm.  The narrower chisels are a good addition to your tool collection, because they allow for removal of waste wood in tight spaces.

V-Parting Gouge

For cutting very fine lines, you may consider buying a couple of  Sankaku To V-Parting gouges. These are especially useful when carving the fine lines of hair or the streaking lines of rain.

Several other types of Japanese tools are available. An excellent source of tools and materials for relief carving is:

Caveat emptor!

As with most purchases, you get what you pay for. Japanese carving tools are made of different grades of steel. The better grades are comprised of two types of steel which are laminated together. One layer, which forms the cutting edge, is made of very hard, high carbon steel. The other layer, which serves as the backbone of the blade, consists of softer and lower carbon steel.

In making the best professional grade tools, the two layers of steel are hand forged. In hand forging, the two layers are heated and physically beaten with a hammer to fuse the steel. It is believed that this process makes a very hard cutting edge even harder.

The two layers of steel can also be fused together through automated factory processing. This manufacturing process produces very high quality steel used in manufacturing more affordable knives, chisels and gouges. The lowest grade of carving tool is made of a single type of extruded steel.


In terms of performance, the higher grades of steel are harder and will hold a sharp cutting edge longer. In my opinion, you should buy the best grade of carving tool that you can afford, if you intend to seriously pursue woodblock printing.
