Pyracantha. Common name: Firethorn
This shrub is Senticous (pronounced Senty Cus) meaning prickly or thorny.
This shrub most certainly is and can be lethal if pruning beyond the new growth.
I think I would think twice before pruning something with thorns like that! One would definitely need to wear heavy duty gloves. You picked a terrific word and this is a great shot for it
We had one of these in front of the house growing up. It must have been in a perfect place because it grew and grew. How my dad hated trimming it back. Thorns! Wicked thorns.
