Well I know most clients wouldn't 'need' a knife, but there is nothing stopping you getting your hands dirty. I've almost always been involved with some part of the gralloch, skinning or butchering and especially barbecuing! In Africa you do have to bear in mind that someone gets paid for doing those tasks and that also means someone most likely takes pride in doing their best for you. I have found that as long as you get involved in a good humoured way and show that its all part of the hunt for you, nobody minds and often you can have a laugh at the same time. Its not about trying to prove you can do it better.
