ら限定されていた。2. Description of the Related Art In conventional saws for both horizontal and vertical sawing, the inner and inner blades are relatively good at scraping the fiber portion when cutting wood, but as shown in FIG. Since all of the inner blades, the middle blades and the outer blades are at the same level, the amount of scraping per sawing was limited from the beginning.

った。Conventionally, there is also a large-sized saw called an improved blade saw (also referred to as a window saw) as shown in FIG. 4, which has a vertical blade for every several horizontal blades and a lower blade portion thereof. Is cut into a U-shape to scrape off the shavings. However, this saw was manufactured by punching out all the blade parts with a press machine, but after that, it was a laborious method of finishing the cutting edge by hand.

提供することを目的とするものである。SUMMARY OF THE INVENTION Accordingly, the present invention provides
It is an object of the present invention to provide a highly practical and epoch-making saw in which the drawbacks of the saw are eliminated in a saw that can smoothly perform both horizontal and vertical sawing with a book saw.

かつ深く構成するものである。DISCLOSURE OF THE INVENTION The present invention relates to a saw composed of an inner blade, a middle blade and an outer blade which are used for both horizontal and vertical grinding, and the pitch of the inner blade and the middle blade is wider than the pitch of the outer blade. And it is deeply structured.

る。BEST MODE FOR CARRYING OUT THE INVENTION When the saw of the present invention is used to start cutting wood, the inner blade and the middle blade are wider and deeper than the outer blade. Since the middle blade is closely attached to the wood and the fiber material of the wood is scraped off so as to be held in the valley portion of each blade, the lateral and vertical cutting work of the wood can be quickly performed.
【０００８】なお、本発明にかかる鋸の目立をするとき

を製作するようにすれば、量産することができる。When sharpening the saw according to the present invention, a numerical control type sharpening machine is used, and the cutting blades having different pitches are manufactured by the same grindstone without replacing the grindstone on the way. Therefore, mass production can be achieved.

である。The arrangement intervals of these three types of cutting blades are as follows.
-Outer blades 4, 4, 4, 4-Medium blades 3, 3-Outer blades 4, 4, 4,
The 4-inner blade 2, 2-outer blade 4, 4, 4, 4-medium blade 3, 3 are repeated. In addition, the pitch of the inner cutter and the middle cutter is wider and deeper than the outer cutter.

の切削効果は多大である。EFFECTS OF THE INVENTION Since the present invention is a saw having the above-mentioned structure, all the fiber portions of the cut wood are held in the deep valleys of the inner blade and the middle blade so that they can be surely scraped out. The continuous cutting work can be performed smoothly and quickly at all times, and its cutting effect as an epoch-making saw that can completely eliminate the drawbacks of the conventional double-sided vertical saw Is a great deal.
