In France February 2l, 1936 The present invention has for its object a tool consisting of the.a combinationof several screwdrivers in 'order that it will serve to operate screws of diiferent sies, and chieiiy adapted for use as I atoolwhich can bereadily transportedin akitor asack,orcarriedi n.thepocket. l

In the accompanying drawing, which is given by way ot example:

At the end opposite the screwdriver part, the 10 'blades have diierent lengths, atrH, I and J, in
