Yamakichi's pull/push saw is a lightweight, compact saw that can be used for a variety of tasks. Hikimawari is the usual pull-and-cut type, and oshi-mawashi is the push-and-cut type. Each can be selected depending on the work site. I think a drag saw is easy to use for general households. The awl at the cutting edge makes a hole in the plate material for the blade to be inserted into, allowing you to process it freely like a scroll saw. *It is not a replaceable blade type. If it stops cutting, replace it with a new one.
