Hi guys I just ordered a victorinox outrider camo version model 55731 from amazon , now I don't know what I will get! I just noticed on youtube that the red version with the corkscrew has some kind of button on the back. smartknives.com and other sites don't say if this 111m has a locking main screwdriver or not. I can not find a picture of the back of this model. I thought I was getting a trekker with and extra scissors and small philips screwdriver . Maybe I should just cancel the order.Does anybody know about this knife? Update: I just found out that the regular red outrider is a sidelock and the main screwdriver does not lock like the trekker. Not good. The camo is a slightly different model wilth no corkscrew . Has any one seen the back of it?
