It is not always the case that bigger knives are the key but for sure size matters in the outdoors. Basically as I see it is correct because a large saw can cut thicker branches. A large blade can cut more material. Basically a large knife is faster and more comfortable. It saves time and it is for sure a better outdoors tool!
It depends on the personal philosophy and use. SAKs are outdoors products for sure. It is a knife designed in the Swiss Army Knife tradition. It is all good.
Size also
matters sometimes in the ability to take more force. One should always remember that wrong use and too much force will damage any knife.
