I agree with heat treating comments, in my post I assumed all heat treatment was done correctly... I think you are missing the main point:
Let me repeat in better detail (assuming you follow the common sense logic not to cut things you are not supposed to):
A. Knife performance = blade steel heat treatment + blade steel composition (chemical)
If knife was not heat treated properly you will experience blade breaking, chippings and just feel that knife is not performing. Period. When you buy the knife, you do ASSUME that heat treating was done properly, since there is no other way of finding out, other than cutting things and EDCing the knife!
B. Now what you can choose and control is the blade steel. What kind of blade steel should you go for that I think is the most important first decision you can make. My very first knife I got had m390 blade and this was the gateway drug for me and that's how I wound up with experimenting, testing blades and collecting knives. I might not be an expert knifesmith, but I do know enough to hold a descent conversation and argue my point with any knifemaker.
Now - all these steels I mention below as DO NOT BUY - these blades can get dull edge pretty fast - just try cutting rope, carpet, cardboard boxes and see how long your blade will last, how long it will maintain its sharpness and how sharp it will be at the end of the day. You will find yourself sharpening your blade pretty much every day or every other day. You might not even be able to peel a potato afterwards.
Therefore,
I DO VERY STRONGLY BELIEVE that the following blade steels (below) are complete BULLSH*T and no descent knifemaker should ever use these again unless you want to put a knife for retail sale under $50.
PLEASE (for your first knife) DO NOT BUY any knife with the following steels: Chinese steels (9cr, 8cr,7cr and lower), any Pakistani steels, 440 steels, plain stainless crap, AUS 8, AUS 8A or below (AUS 7 etc), AUS 10, AUS10A, VG10, N690co,
Non-American D2, RWL, 154cm.
Get any knife with these steels (assuming they have been heat treated properly): CPM M4, M390, CPM 20CV, CPM S90V, S110V, 10V, 3V, Elmax, American-heat treated D2 (Greg Medford does fantastic job)....
The logic behind: FOR ME PERSONALLY (and that's where I am giving my advice from, from my own personal experience & view) Knife is a mutliuse cutting tool, you should be able to slice an apple, cut a rope, cut a cardboard, wood, cut a car door out or take down a concrete wall. That's why I carry Medford Fighter sometimes, sometimes I carry Cold Steel 4 Max, Cold Steel Espada XL.... knives that might seem insanely big for others, for me just a cool big EDC blade.
That's all. Don't get too upset with my views and opinions. I am glad to discuss and explain you my viewpoint.
