GYOKUCHO Razorsaw Kariwaku 330 EVA - 13 in Heavy Duty Japanese Pull Saw (No. 507)

A heavy-duty Japanese pull saw built for construction and rough carpentry. The GYOKUCHO Razorsaw Kariwaku 330 has coarse, aggressive teeth that tear through plywood, dimensional lumber, posts, and logs quickly—originally designed for concrete formwork (kariwaku) on Japanese jobsites. The slim, tough blade and long EVA grip allow two-handed cutting for power and control on heavy stock.
