The
integral bolster knife is something really connected
to the Brazilian knife culture, specialy to those of
southern origin, where we grew up alog with the Gaucho
culture.
The design of this kind
of knife is very apealing and it can only be made by
forging, and it is a true skill test for any bladesmith.
With the recent internecionalization of Brazilian custom
cutlery the integral bolster Gaucho knives have become
extremely popular in the US and Europe and this is one
of the reasons this tutorial was made.
This tutorial was made
with pictures taken during the second SBC forging demo
in 2003. The blade was forged by Rodrigo Sfreddo and
Ricardo Vilar, and the tutorial was put toguether by
Francisco Ferrari as educational pomoting of the Brazilian
Bladesmiths Society.
All I have done was to
translate the information and added some pictures I
had previously taken to help illustrate the article,
as well as to develop a little further some of the explanation.
I hope you all enjoy this article as much as we did
putting it together.

First
of all you need your tools and stock. We use 1" round
stock for our knives, usualy 52100. Hammers, tongs
and a spring
fuller, and latter on some sort of grinder. This is
a hidden tang handled knife. You can slightly modify
the instructions here for a full tang handled knife.
We will get into that latter on.
We start by heating the
steel and marking the beggining of the blade with a
spring fuller tool. Be sure you leave enough material
in front of the marking in order to forge the blade.

The tools you will need

Using the spring fuller tool, mark the
beggining of the blade.

The marking is done.
Now we start to bring
material down to forge the blade. Just be sure yu leave
plenty of stuff to work with. If you forge it too thin
you might get short on steel when finishing the blade
shape.
