You know how pesky it can be to remove some technic axles? Barman did too, so he created an axle pin removal tool. Build one, tuck it in your utility belt and be a LEGO building Batman, ready for any tricky technic situation!
Steve and John did their job every day, yet they never stopped to consider that their tools might be too small for the task. After all: everything is cool when you're part of a team.
