Treatment to attain Wrench like Surface Toughness?
(OP)
I am working with a machine shop to fabricate a specialized puller. The puller will see its fair share of hammer blows. I noticed that many of my wrenches, pullers, bearing splitters, etc. show very minor signs of wear, but have been abused for many years. I would like the puller to have the same surface toughness, one that shows very little wear. The base material is 4140 and is sufficient for the puller's function. I just need to specify the treatment of the surface. I have searched the web for such information which I thought would be common knowledge since thousands of retail hand tools have indestructible surfaces...unfortunately, I cannot find.
It would be much appreciated if someone could point me in the right direction or let me know the common practice or process. Thank you

Regarding 4320, I will research your recommnedations further...thank you
I thought someone from a tool design background would have a standard heat treat process, whether forged or not. I had a contact at Proto tools but cannot find anymore. In other words, looking for basic process to spec. a new tool...forge tool, then heat treat how? Or for example, an engineer designs a new tool for Snap-On...how would the heat treatment specification read?
