I have been using Staedtler pencils (and erasers, lots of them) since art school, and I have never looked back. They have always made a high quality, reliable product. I especially like the HB (although I would never turn down a 2H either). Staedtler pencils provide the foundation of all of the Land of Le Beef sketches.
The pens that I use, Uni Pin by Uni-Ball, are a relatively new find for me. When I started the Beef a couple of years ago, I didn't put too much consideration into which pen I used. Eventually I had bought a bunch of pens just to try them out, and I would just randomly grab one whenever my sketches were ready for ink. Some pens would frustrate me by how fast the ink flowed, or their lack of precision, but I always felt great when I had a Uni Pin in my hand. Now I can't imagine using anything else. They come in different thickness; I typically use 0.2 for the main lines, and 0.1 for small details and shading. If I happen to be doing a larger illustration I might use a 0.3 or even the 0.5.
Anyway, to sum it all up, thanks Staedtler and Uni Pin. You're awesome.
