Wire bending at sharp angles


I am trying to bend wire (for boom vangs and rigging screws) at a sharp angle. I want to achieve a "V"shape bend, but all my efforts result in a small "U" shape at the bend. I ordered a wire bending jig from Amazon, but it is not meant for the small gauge wire. Any ideas? What do some of you do to get that sharp angle?

So, it is not possible to bend in "V" shape, but I assume you need a very small "U", right?
Most tools I've seen allow for up to 90 degrees bend, that is when they hit the limit of their geometry. Like this one: https://www.youtube.com/watch?v=OIOXfqDXuV0?t=1

I'll say you need to start with the 90 tool, and then continue with handtools. Watch this (1:20 mark):

Micro-Mark still sells the set of metal forming pliers that I've been using for, I don't know, 30 years or so. Perfect for all kinds of hooks, etc.:

The other thing to get is a hand vise. With those two you should be able to form just about any wire shape.

The micromark pliers are awesome, highly recommended. Also check out the Dubro quick twist tool. The Youtube video on it is great. Ryan

It looks like "minimum bend radius" is also called formability.

It looks the that number (where cracking is not observed) is VERY dependent on the material and tooling. It looks like brass wire has a minimum radius of "one" so you could make a 90*!of a 30 thousands wire on the shank of a 30 thousand drill bit.

If you need a sharp corner you can use a file to remove material or silver solder to add. Just made sure you have the mechanical strength you need.
