The 4.2 seems to fit my hand just perfectly and has been my most carried edc fixed blade lately. The 4.5 is really nice as well. The 11 and 12 are close in size, but it is amazing how much ‘wallop’ I can generate with the 12 while doing trail maintenance at my cabin. I love all their knives!I do like the 3 but yes a larger version would be better for me I will see if I can find the 4.2 or 4.5
