Japanese saw
The Japanese saw (also: Japanese Saw, Japanese锯, nokogiri ) is a handsaw and the Japanese counterpart to the widespread in Europe jigsaw or a handsaw. In contrast to these saws a Nokogiri works exclusively on train.
While on pressure acting saws require a relatively broad and rigid sheet and can bend anyway, this principle of traction Japanese saws allows a thinner blade ( 0.3-0.6 mm, in Zimmermann saws and up to about 1 mm), which is very fine sections allowed with little effort. Due to this property, the popularity takes this Sägetyps to outside Japan. Japanese saws are used in many areas of woodworking and processing application, such as carpentry or tree care:
Saws types
- The Dozuki (胴 付き(锯) Dozuki ( noko ), " saw with body " ) is a single -toothed saw back. It is mainly used for precise cuts, similar to the European Feinsäge.
Dozuki decomposed into handle, back & saw blade
Dozuki saw blade Cutting width 0,3 mm
- The Kataba (片 歯, "one-sided teeth ' ) is a single -toothed saw without back. This is used for large and deep cuts, even in carpentry.
Kataba: Saw blade cutting width 0.6 mm
Kataba: the saw teeth are ground in three areas and slightly restricted.
- The Kobiki (木 挽, " wood saw " ) is used for separation of boards or unset version with the narrow carved back for tree care and pruning trees.
- The Kugihiki ( (木)钉 挽, (Ki) kugihiki, ' (wooden) Nagelsäge " ) is for flush sawing eg dowels. The gearing is not restricted, so that the saw can be placed flat on the material from which protrudes the anchor.
Kugihiki ( unset, ground teeth )
- The Ryoba (両 歯, " Double teeth " ) is a double -toothed saw. A page with triangular teeth used exclusively longitudinal sections, the other with trapezoidal teeth transverse or oblique cuts in the wood.
The blade is forged with the traditional fishing in one piece, more modern saws often have replaceable blades, which are fixed in the handle with a screw. The rod-shaped wooden handle is about 20-30 cm long with an oval cross-section. It is wrapped around the length with To ( rattan cane ).
Disadvantages are really just for inexperienced or inattentive users and have an increased risk of injury due to the extremely sharp teeth, and the slight bending of very thin blades with poor saw guide. Since these saws extremely removing too much metal and produce a very narrow slit, its cutting direction can be (usually by the tilting of the saw) no longer correct. You must start the cut at the beginning correctly. It is advisable to practice the handling before editing valuable objects.
The high-quality saws described here are difficult to distinguish externally from the often vorzufindenden, cheap imitations with similar appearance but of inferior materials and poor workmanship. The difference to the higher value, both saws in principle be observed in the smoothness of the cut, as well as of a significantly extended life of the specially hardened teeth.
