Jeeeee-sus! That video gives me nightmares and is the reason why I run a capping workshop before (and on) exped.
Please, anyone who reads this and has pesky rocks in digs which need removing, reach out to your local club where there should be at least someone who has managed to keep all fingers for a while (though toes are arguably at a higher risk).
Alternatively Badland or myself (amongst many more I'm sure), I cannot claim to go through hundreds in a day but go through a fair few.
Capping, like many activities, is inherently dangerous. There is equipment and methods you can use to minimise that risk to yourself and those around you. It's well worth doing so.
In my opinion plug and feathers are only suitable for those with a vast reserve of patience, space, and battery power.
Here is an idea why safety specs are an absolute necessity, I've lugged all my kit out of a pretty long cave before, realising I'd forgotten the safety specs on reaching the site. I'd 100% do so again.
