As a lefty, the Wengers are not easy to open one-handed. I prefer the OHT/Soldier for that reason. As to the saw, I occasionally use one at the store to cut wood for stain samples. I haven't used the 111mm one yet at work, but I have used the one on my Farmer. The 93mm worked great, no reason to think that the 111mm won't be just as good if not a bit better. I took it outside and sawed a couple of branches just a little while ago, and didn't fint the OHO hump to be uncomfortable.
