29 Did Jesus tell his disciples to carry a staff?

Mr. Mark vs Mr. Luke

In the Gospel of Mark, Jesus commands the disciples:
To travel with a staff and sandals

Hold on there! 

In Luke, Jesus tells his disciples:
Don’t go with a staff and sandals

In Mark, Jesus sends out the Twelve with staff and sandals

Mark 6:8 These were his instructions: Take nothing for the journey except a staff-—no bread, no bag, no money in your belts. 9 Wear sandals but not an extra tunic. 

But in Luke, Jesus sends them out with neither staff nor sandals

Luke 9:3 He told them: Take nothing for the journey--no staff, no bag, no bread, no money, no extra tunic.

Luke 22:35 Then Jesus asked them, "When I sent you without purse, bag or sandals, did you lack anything?" "Nothing," they answered. 

Recap: Mark says Jesus tells his disciples to go forth with a staff and sandals. But Luke says he orders his disciples to do the opposite. It seems one of the authors made a teensy-weensy mistake.
