Actually, if you used pencils...you could just erase the unwanted crud.
Niiiice

I do lots of erasing.

And my pencil writing is just as vivid. Pens just aren't as smooth, either.

@unclejr - Did you hear the Sidney Morgenbesser anecdote?

So, an Oxford linguist was giving a lecture at Columbia University, and Morgenbesser was in attendance. The speaker claimed that in many languages two negatives make a positive, but in no language do two positives make a negative. Morgenbesser was heard to have said, "Yeah, yeah."

Not that that has to do with anything...

My process for mathematics involves doing everything wrong once, then erasing it, then doing it over again. Pen just wouldn't work for me.

Tried out the Levenger. It's weighted funny. I'll stick to my Rotrings.

ordered the rotring 600 (old style) today. hopefully it gets mailed out on monday, should have it by the middle of the week.

the levenger l-tech is nice but not my cup of tea. thankfully i didnt get it engraved, and the nice people there took it back less shipping which wasnt too bad. hopefully the rotring is as nice as everyone makes it out to be.

when i do math, i keep all the stuff that is wrong. more than often i use those sheets when i get stuck on a proof. your mistakes offer more insight into subtle mathematical constructs than just a bone dry theorem does. i just strike a line through the incorrect portion and move on. works lovely.

this thread is quite interesting for me ( havnt used a pencil in over 5 years)

Well, my rotring 600 finally arrived, and boy is it impressive. Much smaller than pictures would suggest! The balance of it is superb, even though it is slightly top-heavy, writing is very easy with it, and I can apply much more pressure which much less strain on the wrist compared with my pentel.

I wonder why they stopped making it, for such a utilitarian beast the ergonomics are superb.

edit: got to try the thing out in class today, and the length of the sleeve meant that such little lead needs to be exposed it never broke! The few times I used it for its actual purpose (drawing lines) it really came into its own.

My Ohto Promate arrived as well! I'll be trying it out "on the field" tomorrow for classes, but as of right now, I really like how securely it holds the lead.

my rotring 600 finally came in. it is a wee bit top heavy and yes, much smaller than the pictures make it seem but so far, man am i impressed. been writing with it for almost 5 hours now with maybe a minute break every 45 minutes or so and usually the base of my palm starts hurting after a few hours but with this, no pain at all. the lead flows freely on recycled paper (cheap and works well with mathematics). i can now understand how monolith could write 6 lines in such a small space. i am no where near writing that small but with a 0.35mm lead, everything is extremely sharp. no bleeding occurs and all the lines are definitive. so far, my favorite pencil. i received a silver one and am planning on getting a black one as well just for those times when i fancy writing with a different color . seems wasteful but given how these pencils are no longer made, i figured having an extra one wouldnt be such a bad idea in the event of a mishap.

I once had a beautiful black Pentel mechanical pencil filled with no. 2 lead. I used it to fill in the circles on the GRE's in the fall of 1982. I've lost that pencil and have rarely picked up one since. I use fountain pen and type a lot (computer, no more mechanical typewriter). Pencil fi make me sad.

man you are OLD!!! i didnt know live even existed before 1985. must have been some weird times without the internet and what not. hehe

pentel seems to have been around for a while. it also seems though that the market is shifting severely towards disposable everything. disposable pencils just make me mad. i hope you keep using pencils for a long time to come.

one interesting thing I didnt think about is that since the grip is very sharp (not in a bad way), the grip roughs up my middle fingernail.

not really a problem at all, I just didnt think that it would do that :P

I certainly can't write that small with a pencil. I use a particularly thin tipped pen to do that.

Congratulations all on getting your 600s. I'm sure you can now all see why I recommended it so enthusiastically. Pretty much every other mechical pencil feels like a child's toy after you use that one.

damn you all! I had to buy 2 rotring 600s - one for me, and one for the one who must be obeyed.
