We had something similar, at the Burger King that I used to work at... It was a tomato slicer, and it really couldn't do much damage...
Despite the 1st aid's "don't use self-treatment", I fixed myself up & could work it again, but did so very carefully...
Not so, at another job, inspecting seat foam with hog wires, that I poked myself with--and there, I bled so much that I needed semi-serious medical attention, and that its where they just threw that box of band aids at me, expecting me to treat myself...
(And then I got the snide comment: "the hog wire DID it?", not: "did the hog wire DO it?", well, really, I just couldn't handle the assembly of that product & the fast inspection needed, much like the I LOVE LUCY episode where Lucy & Ethel were wrapping chocolates in the candy factory they were working at...)
