Re: make - forge? - wedge for feathers-and-wedge rock-split

I'll look into this.
"In the moment" response - this is using small charges about the size of
an "AAA" battery?

I've seen videos of in the USA.  Apparently given a specific exemption
as "not explosives" because they won't detonate "unconfined".  That
while for-purpose, are engineered to be impossible to use for nefarious
puposes...
???

If so, didn't know you could get them in the UK.  Assumed without
checking that like side-arms - what you are free to do in the US and is
normal is completely prohibited here...
Cavers use...
Can visualise that - crawling along in a tiny space, having to carry
any kit in such journey, and no space to swing a sledgehammer if you
come to an obstruction...

Apologies if "got the wrong end of the stick".
