Knife design best utilize 4V

[PMQ]

CPM 4V is an in-between steel, good toughness, good wear resistance, good corrosion resistance (for non stainless), a jack of all trades, master of none.

I know that 4V is very popular for competition chopper because of it's edge stability, so that obivously design that will do 4V justice.

What design do you think will bring forth the best characteristics of CPM 4V?

Puukko and leuku.

Probably something shaped like a knife, ground down to a thickness of a knife, and hardened appropriately for the task it’s made for. Make something you’re interested in and report back.

4V supports thinner geometry than other steels. It's stong but tends to fail catastrophically. Use it for an application that benefits from thin geometry that will be subjected rough use that doesn't necessarily need to be indestructible. We use it in competition choppers. I wouldn't use it in a lawnmower blade or a folder but it's fantastic in many applications.

Yes, I know that we're suppose the first look at the intended use of that knife, then choose the appropriate design, geometry, steel, hardness,...

But right now I'm just fiddling around/try out 4V, I don't have any specific use case yet.

rough use that doesn't necessarily need to be indestructible

I'm thinking of a "cardboard shredder".

Competition cutter. Like CPM M4.

I like the higher toughness steels around the 4v range for field/hunting knives. They can do the task well, hold an edge for a decent amount of time and most importantly can be run with nice thin geometry
