Title: Japanese chisel hammers?
Post by: Mac53 on August 10, 2012, 06:28:09 PM

Normally would think to post something about hammers like these in the metal section, but they specifically say they are to be used for chisels? What would make a chisel hammer any different? Could something like this ever be used in forging, or is that a big no-no? .... I'm assuming they mean wood chisels, but I suppose they could mean stone or metal? Anyone know anything?

If I am reading the (somewhat humerous) translation correctly, they are being made in a single heat , within a very narrow temperature range, to produce a fine grained steel. This will make them very tough, fairly hard, and very uniform.

The only thing I suppose would be a no-no is hitting another hardened steel object (like your anvil) with them...

I am thinking 'chisel hammer' is more of a poor translation than a specific use (ie a hammer for striking another tool)
The hammers you don't want to use for striking another tool are the ones that are soft inside and hardened only on the outside.
