I believe it is a Japanese Flush-Cutting Saw with about a 6" blade.

It can be used for trimming through tenons, dressing dovetails and trimming plugs flush with a surface.

It is tapered from tang to tip to give flexibility and from tooth to back to eliminate binding since it doesn't have any set in the teeth.

(The above description borrowed from Lee Valley catalog).
