I don't own your particular model, but I do own a crosslock. I have sung the praises of this knife for years now to anyone who would listen, and many who wouldn't, I love my Crosslock.
I have abused the heck out of this knife and never had it fail. some will say the steel is not the greatest, and they'll be right, but it has always performed.
I change carry blades a lot but for some reason My Crosslock shows up in my pocket on a very regular basis.
I'm not sure how well I'd like the ones with more than one blade because of the thickness aspect, but I'd sure give it a chance.
Buck has incredible customer service as well.
