Been wanting a prybar to go with my copper EDC stuff for a while but I was worried copper wouldn't be strong enough. Found this old wrench on ebay for $10 and modified it for my needs. Left one of the wrench jaws on there so there's two ways to use it as a prybar. The spike end is rounded enough to probably not tear through a pocket but tapered enough to splice rope or tighten knots. Ended up being 5 1/2" which is a nice size.

https://en.wikipedia.org/wiki/Beryllium_copper

Inhalation of dust, mist, or fumes containing beryllium can cause chronic beryllium disease, which restricts the exchange of oxygen between the lungs and the bloodstream. The International Agency for Research on Cancer (IARC) lists beryllium as a Group 1 human carcinogen. The National Toxicology Program (NTP) also lists beryllium as a carcinogen. Copper beryllium alloy containing less than 2.5% beryllium (in copper) is not designated as a carcinogen.
