For sure without a thought it has to be the spyderco PM2. where do i start this knife is ALL wrong. I mean cmon... Just kidding i love all my blades and you get what you paid for not included a few hidden gems here and there. If there was a single knife that didnt feel right with me it would be the xl manix 2. I know sooo many people love this knife and i heard so many great things but really held off buying one for the longest time. When i did i was pretty dissapointed, FOR ME it left a lot to be desired and just didn't seem to mesh well with me. I still have it because i hoard blades but poor thing hasnt seen much sun in a long time. I should really find it a good home but its the only manix 2 i have so whatever
