Another design created as a reference for a freelance project. I thought I'd share in case it's useful to anyone!
Here's the specific model: STAEDTLER 511 63BK
Modeled in Onshape, the blade aspect is only approximate, as the overall shape/form is what I was after with this design. I think it comes close, though I'm not quite sure.
Cheers! Feel free to use as you'd like for any projects commercial or personal.
