Because the hammers we are using don't respond to needling in the same way. NY Steinway hammers, which I use on NY Steinways (a large percentage of my hammer replacement jobs) need some hardening. Likewise, Isaac and certain Ronsen hammers also need the application of hardeners. When I encounter Renner, Abel, Yamaha, Kawai or other hammers that call for needle techniques, that's what I use. Hopefully, people aren't using hardeners on these types of hammers.
