Our 6.5 oz. Shinzan Blacksmith Hammer is forged and shaped by hand from the best quality hammer steel. It is tempered to be soft on the inside and hard on the surface so that most of the impact is transferred to the work surface. In addition to small forging work, this hammer is great for tapping out plane irons and adjusting wooden planes as well as other tasks around the workshop.

He continues to refine his Hi-Zukuri forging techniques to produce the very best quality hammers. The handle is hand shaped Japanese White Oak. Total weight is 9 ozs and overall length is 8¬˝.
