Wait... I love Spyderco... and I also love older knives, especially ones designed from 1869-1929, like the Douk Douk, K55, all those, and those are like, one of my first-line EDC knives. But is this a serious question, what Spyderco is as durable or as slicy as a Douk-Douk?
A Chaparral? I got a dull Chap, and I thought it was sharp originally because of how slicy the profile was, it was working even though it was skipping off fingernail. A Manbug wharncliffe? Any thin ground blade with a good lock?
my spydy gb2 has an amazing hollow flat grind, slicy as can be, nice cpm-m4 steel, its quite a performer
