Choose your weapons or “Putting the lead back into your pencil”

Today I want to nerd out about pencils.
For the longest time my weapon of choice has been a Uni-ball Shift Pipe Lock Drafting Pencil



The upper body shifts forward to create a body transformation as it protects the guide pipe and lead from breakage. I carry mine all the time to this helps out when I drop it.
Today i learned that Rotring has one that brings the guide pipe in on itself and doesn’t require you to reduce the lead before you protect it. For me, that TOTALLY makes it worth $82.50
