Talking of pricks,
I use* Multiclix:
Just a roll of its barrel
And the old ones skedaddle;
With settings for deep or the slightest of snicks.
*Where “use” doesn’t imply self-gratification, though all of Accu-Chek’s repertoire resemble hobbit-dildos. My current favourite (as far as suggestive shape goes), is Bayer’s Ascencia Microlet – it looks like something you could shave your legs with, one hair at a time
