HARIMAKO™ is a profile gauge used for investigating relic in archeology and investigating buried cultural properties. However, since various profiles are possible, how to use depends on your idea. Although the conventional profile gauge is made of bamboo in many cases, HARIMAKO™ uses tool steel and aluminum with special processing. It is possible to draw a precise line because a very thin needle is used. Also, since the tip is finished in a gentle shape, there is no worry of hurting the object.
