have the sandvic 13c26 (the tanto. it wouldn't be my first choice but they had it at wal-mart so I thought "why not") blur and I love it!
it takes a great edge easily, has a nice thin grind (mac said the grind on mine was different/thinner then his friends though, so idk, maybe the tanto is different) I like the grippy stuff on the handles, although it can be rough on your pocket sometimes, AND it opens pretty fast (not as fast as my little scallion though) and even after I batoned some wood it opens nice. (and some people really don't like it, but i do)
it is a liner lock though (but it's not too bad) and the edge rolls/deforms VERY easily.
idk why.
it kind of acts like a carbon steel???
so you may have to like align the edge after use.
other than that I really like mine.

I don't know anything about spydies, never really handled one.
