Back to the topic at hand.
Judging by the sword you want, you want something that is more-or-less no frills working sword.
I would hesitate to call it a sword if you plan on using it for hacking branches or otherwise misusing and disrespecting it in such a manner. But it is your perogative to do what you wish with it.
For steel...take your pic. Are you making the blade yourself? Practice and explore. Are you going to have a custom maker build it for you? Ask him what he is most familiarized with and which materials he is most pleased with his methods.
I do not deny CPM3V in capability, it's a fine and dandy steel. Good for it. If the maker isn't happy with using it and feels he could make a better blade of something else, then by George let him give it a whirl doing it his way. But it's a great steel and when worked right will result in a blade you can be proud of.
5160--Good steel! Great properties, heat treats nicely, very forgiving to errors. Heat treats nicely and will last. Again, if this is what the maker thinks will do a great job, don't worry about it!
1050, 1060, 1084, etc...simple steels are all great when treated right. Also easily accessible and so on.
Screw the bickering and arguing about which steels are superior to others. The game is a series of tradeoffs...you aren't going to make an inferior blade unless it's worked and heat treated in an inferior way.
The steel is only part of it. You can take 1045 and make a decent sword out of it if ya want.
Part of what makes blades special is the individuality imparted into each piece. If we try to force one steel or another down a person's throat, are we giving them the benefit of choices and experimentation?
When will we stop bickering about it? Honestly, I could give a damn less about this or that steel. These threads turn into a flame war that is absolutely pointless.
If you run across a maker who suggests using 3v, and you plan on having him make the blade, then let him make it out of 3v.
If you want to make the blade yourself, try stuff out, find what works for you, grow with your expanding knowlege and make the best damn things you can with whatever you can.
1075, L6, 3v, 420v, A2, D2, O1, W2, 1050, 5160, 52100, M2, S5, etc etc etc will all yield great blades when done well. Take your pic, and find a maker who will do a good job with it. I like traditional swords, so I'm biased here, but if you want a "modernized" sword, you can pick whatever simple steels or alloys you want. You can still get a hell of a blade.
Good luck,
Robert.
