Hell yeah 2.5 inches is plenty of useable blade-and nowadays Federal buildings won't let you take a Swiss Army Knife Classic in there, the VA hospital and office downtown won't let you in with any knives period. The Buck Paklite Skinner is one of my favorite small knives and it comes in at 2 7/8, there are plenty of cool bird and trout knives out there, the AG Russel Woodsman, the Bark River Bumble Bee... for a slicing blade, 2.5 inches is PLENTY big.
