This 4oz Grace Brass Hammer is made for the firearms industry, but it is very useful around my woodworking shop. Its compact, well built, and perfect for assembling and disassembling furniture, adjusting plane blades, and anytime you want to tap some metal without marring the metal or creating a spark. I mostly use my brass hammers for adjusting the blades on planes that do not have adjustment mechanisms such as a scrub plane or chisel plane, but there are lots of other uses. High quality 360 brass heads Available in 4 oz and 8 oz heads. Seasoned hickory handles We sand the top of the head smooth then wrap the handle with hockey stick tape for a better grip. Made in the USA
