Where do you get titanium arrow heads? That sounds great. Are they broadheads? Currently in Canada we can only use razor blades (although I plan on following none of the laws in an emergency).

I also believe that there is available a Titanium Axe head as well as your Titanium crow bar. But for a cutting tool rather than a prying tool the Gransfor axe models are probably better in the long term as long as they are looked after and kept clean.
