We all have favorite knives (EDC or otherwise). But rarely do we come across a knife that is "perfect". IMO there is no such knife (for me). My tastes change over time so I buy more knives. It's an endless cycle and one that I enjoy.
Anyway , if you could change just ONE thing about some of your favorite knives what would it be ?
For me : BM 710 = I'd like an upgrade in blade steel from D2 on the standard model.
Manix2 = I wish the blade was more hidden when closed. It's a wide carry as is.
Buck 124 = Great knife. But the 420 HC dulls rather quickly. Steel upgrade please.
Nirvana = I love this knife. Just wish the blade didn't have a bead blasted finish. It looks awesome but I hear the small pits in such a finish can trap moisture and cause corrosion.
All of the pros far outweigh the cons concerning my favorite knives. Or else they wouldn't be my favorites. Just nitpicking.
