Prybars ... Viable metals instead of stainless/tool steel & titanium?

    Like many of you, I'm a fan of keychain and pocket prybars of all the favorite designers/companies (Atwood, JDR, JRP, Lee Valley Tools, County Comm, STP over at the Knife Forums, Boker, etc.).

    I was just wondering if any of you have run across any of these archetypical prybars that are *NOT* made out of stainless steel, tool steel or titanium?

    Due to metallurgical structure and stress issues, I can see why the field of viable metal types are few and far-between. But I would tend to think there's got to be some cost-friendly alternatives. For example, can brass be processed or shaped to a decent keychain prybar? It has some advantages - it doesn't spark from impact, it has an arguably warmer visual aesthetic, and is less likely to mar delicate contact surfaces (since it is softer than steel). :knuppel2:

    Any other metal candidates for keychain/pocket prybars?

    Pedantic maybe but Talonite is not steel or titanium. (Yes I know it's pretty close to a Steel but without that Carbon...) :)

    I thought that brass was more flexible than steel which would make it less suitable for a Prybar. However I'm sure you could make a steel prybar coated with brass for the spark/marr protection...

    Talonite would be awesome! It's pretty much considered to be the pinnacle of rust-resistant metal. Expensive as hell though. A number of skilled knifesmiths over the years have experimented with talonite knives ... and now those knives are worth an ungodly amount of money. I think Peter Atwood did a small prybar-knife in talonite a year or 2 ago. You'll never see them on eBay. If you did, I'm sure they'd go for $750 or higher.

    Peter's done a couple of knives in Talonite - I understand there are a very small number of Talonite Skeeters (maybe 2!) and there are certainly some Talonite MSoPTs around, I have one...

    I'm also liking your brass/steel hybrid idea.

    Although I don't know if "coating" is either cost-effective or metallurgically reliable/robust.

    Brass would be too soft for a pry tool, would have to be combined with something harder!

    bronze would be harder than brass, but I think it would be brittle.

    Bronze actually would be pretty good if the right alloy is used. This is whats being used on some watch cases:
    UNI 5275 Bronze Alloy - Nickel Aluminum Bronze (CuAl11Fe4Ni4)

    Mechanical Properties [Typical] Continuous Cast
    Yield Strength 300 MPa
    Ultimate Tensile Strength 680 MPa
    Typical Hardness 200 HB (Brinell)



    It has pretty good corrosion resistance, and of course, it takes on a great patina.

    I'm also thinking maybe carbon fiber with embedded steel or titanium at the pry points might work.

    It's also odd that we aren't seeing some enterprising individual making a small prybar out of polymer composites. While the thick chunky part of the prybar is likely conducive to plastics .... the serious load-bearing part of the thin pry tip is likely the problem.

    Something Tungsten based ?

    Tungsten is hard but I'm not sure it's quite the right material to take that kind or torsion, I have a suspicion it could snap! Hopefully someone who knows more about materials science will chime in!

    I would imagine it would be quite expensive too, and I also wouldn't be surprised if it could spark...

    Composites sound interesting and I'm sure it's technically possible to make a sturdy composite pry-bar, but I doubt it would be a simple bar, I suspect it would require a much more complex construction!

    Rhodium would make one hell of a tool but it is many, many times the price of gold or platinum.

    Can't see the forces being that great for a key chain pry bar. They do make wedding rings out of tungsten carbide. And I think the alloys with nickel & copper make it less brittle if that is a problem.

    Closest existing thing I can think of would be bicycle tyre levers.
