Stone knife

Japanese: 石刀 - せきとう
Stone knife

One of the polished stone tools from the late Jomon period. It is a stone tool with a shape similar to a Japanese sword, with a wedge-shaped cross section and a blade on one edge. There is a blade groove where the blade meets the handle, and the head is bumpy like a stone club or stone sword, and some are decorated with patterns. In rare cases, there are grooves or patterns on the back. It differs from a Japanese sword in that the entire tool is curved inward. It is distributed mainly from southwestern Hokkaido to the Tohoku region, and spreads west to the Kinki region. There are also examples of it being buried as grave goods in pit tombs, and it is thought that it was used as a non-practical tool rather than for practical purposes. Many are made of chlorite schist and slate.

Japanese:

縄文時代晩期の磨製石器の一つ。日本刀に似た形状を呈す石器で、断面が楔(くさび)形を呈し一側縁に刃がつけられている。刃と柄(え)の境に刀関(はまち)をつくり、頭部は石棒、石剣と同様に瘤(こぶ)状を呈し、文様が施されるものがある。まれに背に溝や文様を施したものもある。全体が内反りにつくられているところが日本刀と異なる。北海道南西部から東北地方を中心に分布し、西は近畿地方まで広がっている。土壙墓(どこうぼ)に副葬品として埋納された例などもあり、用途は実用的なものではなく非実用的な道具として使用されたと考えられる。緑泥片岩(りょくでいへんがん)、粘板岩(ねんばんがん)製のものが多い。
