Boring,
also
called parbuckling, is the hardest part for a wooden shoe
maker. The profession of making wooden shoes stands or falls
with a well fitting wooden shoe.
As
shown above, the first step is to make a well fitting hole
for the heel of the foot. For this the wooden shoe makers
uses a gouge as shown in fig. 12.

When the hole for the heel is large enough, a
large drillknife is used to finish the hole (fig. 13)
This
tool is again wielded in a totally different way than the
previous ones. An aspect that makes this profession so
fascinating.
As shown on photo 29, the wooden shoe
maker uses his complete fore-arm. This is necessary because
boring needs to be done "out of the hand". For he can't let
the shaft of the knife lean on the edge of the wooden shoe
because it will then tear off. By scooping out the wood he
creates sufficient space inside the back of the wooden shoe.
Such a drill is also called a scoop or
spoon. Several types exist: The large scoop, the chasing
drill and the large and small spoon. The described
application of these drills is simply called drilling in Limburg (a
southern province of Holland). In other areas of Holland
like in Brabant or De Achterhoek it's called parbuckling. (Dutch
words are uitheulen,
uitboren and schrooien).
