CPM M4 is a first class steel but does require maintenance against rust but edge retention is higher then other steels available under the $100 mark that I am aware off. I have 3 knives in the steel and I use my knives for hard cutting chores.
The other knives worth mentioning is the Spyderco Paramilitary 2, Benchmade Bone Collector, Griptilian with D2...those are the first that come to mind.
A Spyderco Endura, Manix 2 or Benchamde Griptilian can also function well for your uses, but one will have to sharpen them a bit more compared to the other steels such as CPM-S30V, D2 and CPM-M4 when used for hard cutting chores.
