I have had a Leatherman Wave for years and have loved it. The cutter got tweaked and started sticking when I would use the pliers, which was a hassle. I sent it back and was rewarded with a new Wave. The locking blades, both straight edge and serrated, are solid and sharp! I use the scissors often. It is a heavy tool, but well worth its weight. I take it on ski/snowboard tours and to camp on climbs (leaving it there when going for the top to save weight).
Bottom line: Great Mulit-Tool with enough features and a great pair of pliers and two sharp and kick ass blades! Highly recommend!
